# WebView

`public class WebView`
`` `` `` `extends AbsoluteLayout` `implements ViewTreeObserver.OnGlobalFocusChangeListener, ViewGroup.OnHierarchyChangeListener`

java.lang.Object
↳ | android.view.View
| ↳ | android.view.ViewGroup
|  | ↳ | android.widget.AbsoluteLayout
|  |  | ↳ | android.webkit.WebView

A View that displays web pages.

### Basic usage

In most cases, we recommend using a standard web browser, like Chrome, to deliver content to the user. To learn more about web browsers, read the guide on invoking a browser with an intent.

WebView objects allow you to display web content as part of your activity layout, but lack some of the features of fully-developed browsers. A WebView is useful when you need increased control over the UI and advanced configuration options that will allow you to embed web pages in a specially-designed environment for your app.

To learn more about WebView and alternatives for serving web content, read the documentation on Web-based content.

`int` | `FOCUS_AFTER_DESCENDANTS` This view will get focus only if none of its descendants want it.
`int` | `FOCUS_BEFORE_DESCENDANTS` This view will get focus before any of its descendants.
`int` | `FOCUS_BLOCK_DESCENDANTS` This view will block any of its descendants from getting focus, even if they are focusable.
`int` | `LAYOUT_MODE_CLIP_BOUNDS` This constant is a `layoutMode`.
`int` | `LAYOUT_MODE_OPTICAL_BOUNDS` This constant is a `layoutMode`.
`int` | `PERSISTENT_ALL_CACHES` This constant is deprecated. The view drawing cache was largely made obsolete with the introduction of hardware-accelerated rendering in API 11. With hardware-acceleration, intermediate cache layers are largely unnecessary and can easily result in a net loss in performance due to the cost of creating and updating the layer. In the rare cases where caching layers are useful, such as for alpha animations, `View.setLayerType(int, android.graphics.Paint)` handles this with hardware rendering. For software-rendered snapshots of a small part of the View hierarchy or individual Views it is recommended to create a `Canvas` from either a `Bitmap` or `Picture` and call `View.draw(android.graphics.Canvas)` on the View. However these software-rendered usages are discouraged and have compatibility issues with hardware-only rendering features such as `Config.HARDWARE` bitmaps, real-time shadows, and outline clipping. For screenshots of the UI for feedback reports or unit testing the `PixelCopy` API is recommended.

`void` | `setWillNotCacheDrawing(boolean willNotCacheDrawing)` This method is deprecated. The view drawing cache was largely made obsolete with the introduction of hardware-accelerated rendering in API 11.

In the rare cases where caching layers are useful, such as for alpha animations, `setLayerType(int, android.graphics.Paint)` handles this with hardware rendering. For software-rendered snapshots of a small part of the View hierarchy or individual Views it is recommended to create a `Canvas` from either a `Bitmap` or `Picture` and call `draw(android.graphics.Canvas)` on the View. However these software-rendered usages are discouraged and have compatibility issues with hardware-only rendering features such as `Config.HARDWARE` bitmaps, real-time shadows, and outline clipping.

## Public methods

### addJavascriptInterface

    public void addJavascriptInterface (Object object,
                    String name)

Injects the supplied Java object into this WebView. The object is injected into all frames of the web page, including all the iframes, using the supplied name. This allows the Java object's methods to be accessed from JavaScript. For applications targeted to API level `Build.VERSION_CODES.JELLY_BEAN_MR1` and above, only public methods that are annotated with `JavascriptInterface` can be accessed from JavaScript. For applications targeted to API level `Build.VERSION_CODES.JELLY_BEAN` or below, all public methods (including the inherited ones) can be accessed, see the important security note below for implications.

Note that injected objects will not appear in JavaScript until the page is next (re)loaded. JavaScript should be enabled before injecting the object. For example:

     class JsObject {
        @JavascriptInterface
        public String toString() { return "injectedObject"; }
     }
     webview.getSettings().setJavaScriptEnabled(true);
     webView.addJavascriptInterface(new JsObject(), "injectedObject");
     webView.loadData("", "text/html", null);
     webView.loadUrl("javascript:alert(injectedObject.toString())");

IMPORTANT:

- This method can be used to allow JavaScript to control the host application. This is a powerful feature, but also presents a security risk for apps targeting `Build.VERSION_CODES.JELLY_BEAN` or earlier. Apps that target a version later than `Build.VERSION_CODES.JELLY_BEAN` are still vulnerable if the app runs on a device running Android earlier than 4.2. The most secure way to use this method is to target `Build.VERSION_CODES.JELLY_BEAN_MR1` and to ensure the method is called only when running on Android 4.2 or later. With these older versions, JavaScript could use reflection to access an injected object's public fields. Use of this method in a WebView containing untrusted content could allow an attacker to manipulate the host application in unintended ways, executing Java code with the permissions of the host application. Use extreme care when using this method in a WebView which could contain untrusted content.
- JavaScript interacts with Java object on a private, background thread of this WebView. Care is therefore required to maintain thread safety.
- Because the object is exposed to all the frames, any frame could obtain the object name and call methods on it. There is no way to tell the calling frame's origin from the app side, so the app must not assume that the caller is trustworthy unless the app can guarantee that no third party content is ever loaded into the WebView even inside an iframe.
- The Java object's fields are not accessible.
- For applications targeted to API level `Build.VERSION_CODES.LOLLIPOP` and above, methods of injected Java objects are enumerable from JavaScript.

Parameters
`object` | `Object`: the Java object to inject into this WebView's JavaScript context. `null` values are ignored. This value cannot be `null`.
`name` | `String`: the name used to expose the object in JavaScript This value cannot be `null`.

### autofill

    public void autofill (SparseArray<AutofillValue> values)

Automatically fills the content of the virtual children within this view.

Views with virtual children support the Autofill Framework mainly by:

- Providing the metadata defining what the virtual children mean and how they can be autofilled.
- Implementing the methods that autofill the virtual children.

`onProvideAutofillVirtualStructure(android.view.ViewStructure, int)` is responsible for the former, this method is responsible for the latter - see `autofill(android.view.autofill.AutofillValue)` and `onProvideAutofillVirtualStructure(android.view.ViewStructure, int)` for more info about autofill.

If a child value is updated asynchronously, the next call to `AutofillManager#notifyValueChanged(View, int, AutofillValue)` must happen after the value was changed to the autofilled value. If not, the child will not be considered autofilled.

Note: To indicate that a virtual view was autofilled, `?android:attr/autofilledHighlight` should be drawn over it until the data changes.

Parameters
`values` | `SparseArray`: map of values to be autofilled, keyed by virtual child id. This value cannot be `null`.

### canGoBack

    public boolean canGoBack ()

Gets whether this WebView has a back history item.

Returns
`boolean` | `true` if this WebView has a back history item

### canGoBackOrForward

    public boolean canGoBackOrForward (int steps)

Gets whether the page can go back or forward the given number of steps.

Parameters
`steps` | `int`: the negative or positive number of steps to move the history

Returns
`boolean` |

### canGoForward

    public boolean canGoForward ()

Gets whether this WebView has a forward history item.

Returns
`boolean` | `true` if this WebView has a forward history item

### canZoomIn

    public boolean canZoomIn ()

This method is deprecated.
This method is prone to inaccuracy due to race conditions between the web rendering and UI threads; prefer `WebViewClient#onScaleChanged`.

Gets whether this WebView can be zoomed in.

Returns
`boolean` | `true` if this WebView can be zoomed in

### canZoomOut

    public boolean canZoomOut ()

This method is deprecated.
This method is prone to inaccuracy due to race conditions between the web rendering and UI threads; prefer `WebViewClient#onScaleChanged`.

Gets whether this WebView can be zoomed out.

Returns
`boolean` | `true` if this WebView can be zoomed out

### capturePicture

    public Picture capturePicture ()

This method is deprecated.
Use `onDraw(Canvas)` to obtain a bitmap snapshot of the WebView, or `saveWebArchive(String)` to save the content to a file.

Gets a new picture that captures the current contents of this WebView. The picture is of the entire document being displayed, and is not limited to the area currently displayed by this WebView. Also, the picture is a static copy and is unaffected by later changes to the content being displayed.

Note that due to internal changes, for API levels between `Build.VERSION_CODES.HONEYCOMB` and `Build.VERSION_CODES.ICE_CREAM_SANDWICH` inclusive, the picture does not include fixed position elements or scrollable divs.

Note that from `Build.VERSION_CODES.JELLY_BEAN_MR1` the returned picture should only be drawn into bitmap-backed Canvas - using any other type of Canvas will involve additional conversion at a cost in memory and performance.

Returns
`Picture` | a picture that captures the current contents of this WebView

### clearCache

    public void clearCache (boolean includeDiskFiles)

Clears the resource cache. Note that the cache is per-application, so this will clear the cache for all WebViews used.

Parameters
`includeDiskFiles` | `boolean`: if `false`, only the RAM cache is cleared

### clearClientCertPreferences

    public static void clearClientCertPreferences (Runnable onCleared)

Clears the client certificate preferences stored in response to proceeding/cancelling client cert requests. Note that WebView automatically clears these preferences when the system keychain is updated. The preferences are shared by all the WebViews that are created by the embedder application.

Parameters
`onCleared` | `Runnable`: A runnable to be invoked when client certs are cleared. The runnable will be called in UI thread. This value may be `null`.

### clearFormData

    public void clearFormData ()

Removes the autocomplete popup from the currently focused form field, if present. Note this only affects the display of the autocomplete popup, it does not remove any saved form data from this WebView's store. To do that, use `WebViewDatabase#clearFormData`.

### clearHistory

    public void clearHistory ()

Tells this WebView to clear its internal back/forward list.

### clearMatches

    public void clearMatches ()

Clears the highlighting surrounding text matches created by `findAllAsync(String)`.

### clearSslPreferences

    public void clearSslPreferences ()

Clears the SSL preferences table stored in response to proceeding with SSL certificate errors.

### clearView

    public void clearView ()

This method is deprecated.
Use WebView.loadUrl("about:blank") to reliably reset the view state and release page resources (including any running JavaScript).

Clears this WebView so that onDraw() will draw nothing but white background, and onMeasure() will return 0 if MeasureSpec is not MeasureSpec.EXACTLY.

### computeScroll

    public void computeScroll ()

Called by a parent to request that a child update its values for mScrollX and mScrollY if necessary. This will typically be done if the child is animating a scroll using a `Scroller` object.

### copyBackForwardList

    public WebBackForwardList copyBackForwardList ()

Gets the WebBackForwardList for this WebView. This contains the back/forward list for use in querying each item in the history stack. This is a copy of the private WebBackForwardList so it contains only a snapshot of the current state. Multiple calls to this method may return different objects. The object returned from this method will not be updated to reflect any new state.

Returns
`WebBackForwardList` | This value cannot be `null`.

### createPrintDocumentAdapter

    public PrintDocumentAdapter createPrintDocumentAdapter (String documentName)

Creates a PrintDocumentAdapter that provides the content of this WebView for printing. The adapter works by converting the WebView contents to a PDF stream. The WebView cannot be drawn during the conversion process - any such draws are undefined. It is recommended to use a dedicated off screen WebView for the printing. If necessary, an application may temporarily hide a visible WebView by using a custom PrintDocumentAdapter instance wrapped around the object returned and observing the onStart and onFinish methods. See `PrintDocumentAdapter` for more information.

Parameters
`documentName` | `String`: The user-facing name of the printed document. See `PrintDocumentInfo` This value cannot be `null`.

Returns
`PrintDocumentAdapter` | This value cannot be `null`.

### createPrintDocumentAdapter

    public PrintDocumentAdapter createPrintDocumentAdapter ()

This method is deprecated.
Use `createPrintDocumentAdapter(java.lang.String)` which requires user to provide a print document name.

Returns
`PrintDocumentAdapter` |

### createWebMessageChannel

    public WebMessagePort[] createWebMessageChannel ()

Creates a message channel to communicate with JS and returns the message ports that represent the endpoints of this message channel. The HTML5 message channel functionality is described here

The returned message channels are entangled and already in started state.

Returns
`WebMessagePort[]` | the two message ports that form the message channel. This value cannot be `null`.

### destroy

    public void destroy ()

Destroys the internal state of this WebView. This method should be called after this WebView has been removed from the view system. No other methods may be called on this WebView after destroy.

### disableWebView

    public static void disableWebView ()

Indicate that the current process does not intend to use WebView, and that an exception should be thrown if a WebView is created or any other methods in the android.webkit package are used.

Applications with multiple processes may wish to call this in processes that are not intended to use WebView to avoid accidentally incurring the memory usage of initializing WebView in long-lived processes that have no need for it, and to prevent potential data directory conflicts (see `setDataDirectorySuffix(String)`).

For example, an audio player application with one process for its activities and another process for its playback service may wish to call this method in the playback service's `Service.onCreate()`.

Throws
`IllegalStateException` | if WebView has already been initialized in the current process.

### dispatchKeyEvent

    public boolean dispatchKeyEvent (KeyEvent event)

Dispatch a key event to the next view on the focus path. This path runs from the top of the view tree down to the currently focused view. If this view has focus, it will dispatch to itself. Otherwise it will dispatch the next node down the focus path. This method also fires any key listeners.

Parameters
`event` | `KeyEvent`: The key event to be dispatched.

Returns
`boolean` | True if the event was handled, false otherwise.

### documentHasImages

    public void documentHasImages (Message response)

Queries the document to see if it contains any image references. The message object will be dispatched with arg1 being set to 1 if images were found and 0 if the document does not reference any images.

Parameters
`response` | `Message`: the message that will be dispatched with the result This value cannot be `null`.

### enableSlowWholeDocumentDraw

    public static void enableSlowWholeDocumentDraw ()

For apps targeting the L release, WebView has a new default behavior that reduces memory footprint and increases performance by intelligently choosing the portion of the HTML document that needs to be drawn. These optimizations are transparent to the developers. However, under certain circumstances, an App developer may want to disable them:

1. When an app uses `onDraw(Canvas)` to do own drawing and accesses portions of the page that is way outside the visible portion of the page.
2. When an app uses `capturePicture()` to capture a very large HTML document. Note that capturePicture is a deprecated API.

Enabling drawing the entire HTML document has a significant performance cost. This method should be called before any WebViews are created.

### evaluateJavascript

    public void evaluateJavascript (String script,
                    ValueCallback<String> resultCallback)

Asynchronously evaluates JavaScript in the context of the currently displayed page. If non-null, `resultCallback` will be invoked with any result returned from that execution. This method must be called on the UI thread and the callback will be made on the UI thread.

Compatibility note. Applications targeting `Build.VERSION_CODES.N` or later, JavaScript state from an empty WebView is no longer persisted across navigations like `loadUrl(java.lang.String)`. For example, global variables and functions defined before calling `loadUrl(java.lang.String)` will not exist in the loaded page. Applications should use `addJavascriptInterface(Object, String)` instead to persist JavaScript objects across navigations.

Parameters
`script` | `String`: the JavaScript to execute. This value cannot be `null`.
`resultCallback` | `ValueCallback`: A callback to be invoked when the script execution completes with the result of the execution (if any). May be `null` if no notification of the result is required. This value may be `null`.

### findAddress

    public static String findAddress (String addr)

This method is deprecated.
This method is superseded by `TextClassifier#generateLinks( android.view.textclassifier.TextLinks.Request)`. Avoid using this method even when targeting API levels where no alternative is available.

Gets the first substring which appears to be the address of a physical location. Only addresses in the United States can be detected, which must consist of:

- a house number
- a street name
- a street type (Road, Circle, etc), either spelled out or abbreviated
- a city name
- a state or territory, either spelled out or two-letter abbr
- an optional 5 digit or 9 digit zip code

All names must be correctly capitalized, and the zip code, if present, must be valid for the state. The street type must be a standard USPS spelling or abbreviation. The state or territory must also be spelled or abbreviated using USPS standards. The house number may not exceed five digits.

Note: This function is deprecated and should be avoided on all API levels, as it cannot detect addresses outside of the United States and has a high rate of false positives. On API level `Build.VERSION_CODES.O_MR1` and earlier, it also causes the entire WebView implementation to be loaded and initialized, which can throw `AndroidRuntimeException` or other exceptions if the WebView implementation is currently being updated.

Parameters
`addr` | `String`: the string to search for addresses

Returns
`String` | the address, or if no address is found, `null`

### findAll

    public int findAll (String find)

Parameters
`find` | `String`: the string to find

Returns
`int` | the number of occurrences of the String "find" that were found

See also:

- `setFindListener(WebView.FindListener)`

### findAllAsync

    public void findAllAsync (String find)

Finds all instances of find on the page and highlights them, asynchronously. Notifies any registered `FindListener`. Successive calls to this will cancel any pending searches.

Parameters
`find` | `String`: the string to find. This value cannot be `null`.

See also:

- `setFindListener(WebView.FindListener)`

### findFocus

    public View findFocus ()

Find the view in the hierarchy rooted at this view that currently has focus.

Returns
`View` | The view that currently has focus, or null if no focused view can be found.

### findNext

    public void findNext (boolean forward)

Highlights and scrolls to the next match found by `findAllAsync(String)`, wrapping around page boundaries as necessary. Notifies any registered `FindListener`. If `findAllAsync(java.lang.String)` has not been called yet, or if `clearMatches()` has been called since the last find operation, this function does nothing.

Parameters
`forward` | `boolean`: the direction to search

See also:

- `setFindListener(WebView.FindListener)`

### flingScroll

    public void flingScroll (int vx,
                    int vy)

Parameters
`vx` | `int`
`vy` | `int`

### freeMemory

    public void freeMemory ()

This method is deprecated.
Memory caches are automatically dropped when no longer needed, and in response to system memory pressure.

Informs this WebView that memory is low so that it can free any available memory.

### getAccessibilityClassName

    public CharSequence getAccessibilityClassName ()

Return the class name of this object to be used for accessibility purposes. Subclasses should only override this if they are implementing something that should be seen as a completely new class of view when used by accessibility, unrelated to the class it is deriving from. This is used to fill in `AccessibilityNodeInfo#setClassName`.

Returns
`CharSequence` |

### getAccessibilityNodeProvider

    public AccessibilityNodeProvider getAccessibilityNodeProvider ()

Gets the provider for managing a virtual view hierarchy rooted at this View and reported to `AccessibilityService`s that explore the window content.

If this method returns an instance, this instance is responsible for managing `AccessibilityNodeInfo`s describing the virtual sub-tree rooted at this View including the one representing the View itself. Similarly the returned instance is responsible for performing accessibility actions on any virtual view or the root view itself.

If an `AccessibilityDelegate` has been specified via calling `setAccessibilityDelegate(android.view.View.AccessibilityDelegate)` its `AccessibilityDelegate#getAccessibilityNodeProvider(View)` is responsible for handling this call.

Returns
`AccessibilityNodeProvider` | The provider.

### getCertificate

    public SslCertificate getCertificate ()

Gets the SSL certificate for the main top-level page or `null` if there is no certificate (the site is not secure).

Returns
`SslCertificate` | the SSL certificate for the main top-level page

### getContentHeight

    public int getContentHeight ()

Gets the height of the HTML content.

Returns
`int` | the height of the HTML content

### getCurrentWebViewPackage

    public static PackageInfo getCurrentWebViewPackage ()

If WebView has already been loaded into the current process this method will return the package that was used to load it. Otherwise, the package that would be used if the WebView was loaded right now will be returned; this does not cause WebView to be loaded, so this information may become outdated at any time. The WebView package changes either when the current WebView package is updated, disabled, or uninstalled. It can also be changed through a Developer Setting. If the WebView package changes, any app process that has loaded WebView will be killed. The next time the app starts and loads WebView it will use the new WebView package instead.

Returns
`PackageInfo` | the current WebView package, or `null` if there is none.

### getFavicon

    public Bitmap getFavicon ()

Gets the favicon for the current page. This is the favicon of the current page until WebViewClient.onReceivedIcon is called.

Returns
`Handler` | A handler associated with the thread running the View. This handler can be used to pump events in the UI events queue.

### getHitTestResult

    public WebView.HitTestResult getHitTestResult ()

Gets a HitTestResult based on the current cursor node. If a HTML::a tag is found and the anchor has a non-JavaScript URL, the HitTestResult type is set to SRC_ANCHOR_TYPE and the URL is set in the "extra" field. If the anchor does not have a URL or if it is a JavaScript URL, the type will be UNKNOWN_TYPE and the URL has to be retrieved through `requestFocusNodeHref(Message)` asynchronously. If a HTML::img tag is found, the HitTestResult type is set to IMAGE_TYPE and the URL is set in the "extra" field. A type of SRC_IMAGE_ANCHOR_TYPE indicates an anchor with a URL that has an image as a child node. If a phone number is found, the HitTestResult type is set to PHONE_TYPE and the phone number is set in the "extra" field of HitTestResult. If a map address is found, the HitTestResult type is set to GEO_TYPE and the address is set in the "extra" field of HitTestResult. If an email address is found, the HitTestResult type is set to EMAIL_TYPE and the email is set in the "extra" field of HitTestResult. Otherwise, HitTestResult type is set to UNKNOWN_TYPE.

Returns
`WebView.HitTestResult` | This value cannot be `null`.

### getHttpAuthUsernamePassword

    public String[] getHttpAuthUsernamePassword (String host,
                    String realm)

This method is deprecated.
Use `WebViewDatabase#getHttpAuthUsernamePassword` instead

`String[]` | the credentials as a String array, if found. The first element is the username and the second element is the password. `null` if no credentials are found.

### getOriginalUrl

    public String getOriginalUrl ()

Gets the original URL for the current page. This is not always the same as the URL passed to WebViewClient.onPageStarted because although the load for that URL has begun, the current page may not have changed. Also, there may have been redirects resulting in a different URL to that originally requested.

Returns
`String` | the URL that was originally requested for the current page or `null` if no page has been loaded

Returns
`String` | the title for the current page or `null` if no page has been loaded

### getUrl

    public String getUrl ()

Gets the URL for the current page. This is not always the same as the URL passed to WebViewClient.onPageStarted because although the load for that URL has begun, the current page may not have changed.

### getWebViewRenderProcess

    public WebViewRenderProcess getWebViewRenderProcess ()

Gets a handle to the WebView renderer process associated with this WebView.

In `Build.VERSION_CODES.O` and above, WebView may run in "multiprocess" mode. In multiprocess mode, rendering of web content is performed by a sandboxed renderer process separate to the application process. This renderer process may be shared with other WebViews in the application, but is not shared with other application processes.

If WebView is running in multiprocess mode, this method returns a handle to the renderer process associated with the WebView, which can be used to control the renderer process.

Returns
`WebViewRenderProcess` | the `WebViewRenderProcess` renderer handle associated with this `WebView`, or `null` if WebView is not runing in multiprocess mode.

Note: By default it returns `true`, but views providing a virtual hierarchy view must override it.

Parameters
`virtualId` | `int`

Returns
`boolean` | Whether the view is visible on the screen.

### loadData

    public void loadData (String data,
                    String mimeType,
                    String encoding)

Loads the given data into this WebView using a 'data' scheme URL.

Note that JavaScript's same origin policy means that script running in a page loaded using this method will be unable to access content loaded using any scheme other than 'data', including 'http(s)'. To avoid this restriction, use `loadDataWithBaseURL()` with an appropriate base URL.

The `encoding` parameter specifies whether the data is base64 or URL encoded. If the data is base64 encoded, the value of the encoding parameter must be `"base64"`. HTML can be encoded with `Base64.encodeToString(byte[], int)` like so:

     String unencodedHtml =
         "<html><body>'%28' is the code for '('</body></html>";
     String encodedHtml = Base64.encodeToString(unencodedHtml.getBytes(), Base64.NO_PADDING);
     webView.loadData(encodedHtml, "text/html", "base64");

For all other values of `encoding` (including `null`) it is assumed that the data uses ASCII encoding for octets inside the range of safe URL characters and use the standard %xx hex encoding of URLs for octets outside that range. See RFC 3986 for more information. Applications targeting `Build.VERSION_CODES.Q` or later must either use base64 or encode any `#` characters in the content as `%23`, otherwise they will be treated as the end of the content and the remaining text used as a document fragment identifier.

The `mimeType` parameter specifies the format of the data. If WebView can't handle the specified MIME type, it will download the data. If `null`, defaults to 'text/html'.

The 'data' scheme URL formed by this method uses the default US-ASCII charset. If you need to set a different charset, you should form a 'data' scheme URL which explicitly specifies a charset parameter in the mediatype portion of the URL and call `loadUrl(java.lang.String)` instead. Note that the charset obtained from the mediatype portion of a data URL always overrides that specified in the HTML or XML document itself.

Content loaded using this method will have a `window.origin` value of `"null"`. This must not be considered to be a trusted origin by the application or by any JavaScript code running inside the WebView (for example, event sources in DOM event handlers or web messages), because malicious content can also create frames with a null origin. If you need to identify the main frame's origin in a trustworthy way, you should use `loadDataWithBaseURL()` with a valid HTTP or HTTPS base URL to set the origin.

Parameters
`data` | `String`: a String of data in the given encoding This value cannot be `null`.
`mimeType` | `String`: the MIME type of the data, e.g. 'text/html'. This value may be `null`.
`encoding` | `String`: the encoding of the data This value may be `null`.

### loadDataWithBaseURL

    public void loadDataWithBaseURL (String baseUrl,
                    String data,
                    String mimeType,
                    String encoding,
                    String historyUrl)

Loads the given data into this WebView, using baseUrl as the base URL for the content. The base URL is used both to resolve relative URLs and when applying JavaScript's same origin policy. The historyUrl is used for the history entry.

The `mimeType` parameter specifies the format of the data. If WebView can't handle the specified MIME type, it will download the data. If `null`, defaults to 'text/html'.

Note that content specified in this way can access local device files (via 'file' scheme URLs) only if baseUrl specifies a scheme other than 'http', 'https', 'ftp', 'ftps', 'about' or 'javascript'.

If the base URL uses the data scheme, this method is equivalent to calling `loadData()` and the historyUrl is ignored, and the data will be treated as part of a data: URL, including the requirement that the content be URL-encoded or base64 encoded. If the base URL uses any other scheme, then the data will be loaded into the WebView as a plain string (i.e. not part of a data URL) and any URL-encoded entities in the string will not be decoded.

Note that the baseUrl is sent in the 'Referer' HTTP header when requesting subresources (images, etc.) of the page loaded using this method.

If a valid HTTP or HTTPS base URL is not specified in `baseUrl`, then content loaded using this method will have a `window.origin` value of `"null"`. This must not be considered to be a trusted origin by the application or by any JavaScript code running inside the WebView (for example, event sources in DOM event handlers or web messages), because malicious content can also create frames with a null origin. If you need to identify the main frame's origin in a trustworthy way, you should use a valid HTTP or HTTPS base URL to set the origin.

Parameters
`baseUrl` | `String`: the URL to use as the page's base URL. If `null` defaults to 'about:blank'. This value may be `null`.
`data` | `String`: a String of data in the given encoding This value cannot be `null`.
`mimeType` | `String`: the MIME type of the data, e.g. 'text/html'. This value may be `null`.
`encoding` | `String`: the encoding of the data This value may be `null`.
`historyUrl` | `String`: the URL to use as the history entry. If `null` defaults to 'about:blank'. If non-null, this must be a valid URL. This value may be `null`.

### loadUrl

    public void loadUrl (String url)

Loads the given URL.

Also see compatibility note on `evaluateJavascript(String, ValueCallback)`.

Parameters
`url` | `String`: the URL of the resource to load This value cannot be `null`.

### loadUrl

    public void loadUrl (String url,
                    Map<String, String> additionalHttpHeaders)

Loads the given URL with the specified additional HTTP headers.

Also see compatibility note on `evaluateJavascript(String, ValueCallback)`.

Parameters
`url` | `String`: the URL of the resource to load This value cannot be `null`.
`additionalHttpHeaders` | `Map`: the additional headers to be used in the HTTP request for this URL, specified as a map from name to value. Note that if this map contains any of the headers that are set by default by this WebView, such as those controlling caching, accept types or the User-Agent, their values may be overridden by this WebView's defaults. This value cannot be `null`.

### onCheckIsTextEditor

    public boolean onCheckIsTextEditor ()

Check whether the called view is a text editor, in which case it would make sense to automatically display a soft input window for it. Subclasses should override this if they implement `onCreateInputConnection(android.view.inputmethod.EditorInfo)` to return true if a call on that method would return a non-null InputConnection, and they are really a first-class editor that the user would normally start typing on when the go into a window containing your view.

The default implementation always returns false. This does not mean that its `onCreateInputConnection(android.view.inputmethod.EditorInfo)` will not be called or the user can not otherwise perform edits on your view; it is just a hint to the system that this is not the primary purpose of this view.

Returns
`boolean` | Returns true if this view is a text editor, else false.

### onChildViewAdded

    public void onChildViewAdded (View parent,
                    View child)

This method is deprecated.
WebView no longer needs to implement ViewGroup.OnHierarchyChangeListener. This method does nothing now.

Called when a new child is added to a parent view.

Parameters
`parent` | `View`: the view in which a child was added
`child` | `View`: the new child view added in the hierarchy

### onChildViewRemoved

    public void onChildViewRemoved (View p,
                    View child)

This method is deprecated.
WebView no longer needs to implement ViewGroup.OnHierarchyChangeListener. This method does nothing now.

Called when a child is removed from a parent view.

Parameters
`p` | `View`: the view from which the child was removed
`child` | `View`: the child removed from the hierarchy

### onCreateInputConnection

    public InputConnection onCreateInputConnection (EditorInfo outAttrs)

Creates a new InputConnection for an InputMethod to interact with the WebView. This is similar to `View#onCreateInputConnection` but note that WebView calls InputConnection methods on a thread other than the UI thread. If these methods are overridden, then the overriding methods should respect thread restrictions when calling View methods or accessing data.

Parameters
`outAttrs` | `EditorInfo`: Fill in with attribute information about the connection.

Returns
`InputConnection` |

### onDragEvent

    public boolean onDragEvent (DragEvent event)

Handles drag events sent by the system following a call to `startDragAndDrop()`.

When the system calls this method, it passes a `DragEvent` object. A call to `DragEvent.getAction()` returns one of the action type constants defined in DragEvent. The method uses these to determine what is happening in the drag and drop operation.

Parameters
`event` | `DragEvent`: The `DragEvent` sent by the system. The `DragEvent.getAction()` method returns an action type constant defined in DragEvent, indicating the type of drag event represented by this object.

Returns
`boolean` | `true` if the method was successful, otherwise `false`. The method should return `true` in response to an action type of `DragEvent.ACTION_DRAG_STARTED` to receive drag events for the current operation. The method should also return `true` in response to an action type of `DragEvent.ACTION_DROP` if it consumed the drop, or `false` if it didn't. For all other events, the return value is ignored.

### onFinishTemporaryDetach

    public void onFinishTemporaryDetach ()

Called after `onStartTemporaryDetach()` when the container is done changing the view.

### onGenericMotionEvent

    public boolean onGenericMotionEvent (MotionEvent event)

Implement this method to handle generic motion events.

Generic motion events describe joystick movements, mouse hovers, track pad touches, scroll wheel movements and other input events. The `MotionEvent#getSource()` of the motion event specifies the class of input that was received. Implementations of this method must examine the bits in the source before processing the event. The following code example shows how this is done.

Generic motion events with source class `InputDevice#SOURCE_CLASS_POINTER` are delivered to the view under the pointer. All other generic motion events are delivered to the focused view.

     public boolean onGenericMotionEvent(MotionEvent event) {
         if (event.isFromSource(InputDevice.SOURCE_CLASS_JOYSTICK)) {
             if (event.getAction() == MotionEvent.ACTION_MOVE) {
                 // process the joystick movement...
                 return true;
             }
         }
         if (event.isFromSource(InputDevice.SOURCE_CLASS_POINTER)) {
             switch (event.getAction()) {
                 case MotionEvent.ACTION_HOVER_MOVE:
                     // process the mouse hover movement...
                     return true;
                 case MotionEvent.ACTION_SCROLL:
                     // process the scroll wheel movement...
                     return true;
             }
         }
         return super.onGenericMotionEvent(event);
     }

Parameters
`event` | `MotionEvent`: The generic motion event being processed.

Returns
`boolean` | True if the event was handled, false otherwise.

### onGlobalFocusChanged

    public void onGlobalFocusChanged (View oldFocus,
                    View newFocus)

This method is deprecated.
WebView should not have implemented ViewTreeObserver.OnGlobalFocusChangeListener. This method does nothing now.

Callback method to be invoked when the focus changes in the view tree. When the view tree transitions from touch mode to non-touch mode, oldFocus is null. When the view tree transitions from non-touch mode to touch mode, newFocus is null. When focus changes in non-touch mode (without transition from or to touch mode) either oldFocus or newFocus can be null.

Parameters
`oldFocus` | `View`: The previously focused view, if any.
`newFocus` | `View`: The newly focused View, if any.

### onHoverEvent

    public boolean onHoverEvent (MotionEvent event)

Implement this method to handle hover events.

This method is called whenever a pointer is hovering into, over, or out of the bounds of a view and the view is not currently being touched. Hover events are represented as pointer events with action `MotionEvent#ACTION_HOVER_ENTER`, `MotionEvent#ACTION_HOVER_MOVE`, or `MotionEvent#ACTION_HOVER_EXIT`.

- The view receives a hover event with action `MotionEvent#ACTION_HOVER_ENTER` when the pointer enters the bounds of the view.
- The view receives a hover event with action `MotionEvent#ACTION_HOVER_MOVE` when the pointer has already entered the bounds of the view and has moved.
- The view receives a hover event with action `MotionEvent#ACTION_HOVER_EXIT` when the pointer has exited the bounds of the view or when the pointer is about to go down due to a button click, tap, or similar user action that causes the view to be touched.

The view should implement this method to return true to indicate that it is handling the hover event, such as by changing its drawable state.

The default implementation calls `setHovered(boolean)` to update the hovered state of the view when a hover enter or hover exit event is received, if the view is enabled and is clickable. The default implementation also sends hover accessibility events.

Parameters
`event` | `MotionEvent`: The motion event that describes the hover.

Returns
`boolean` | True if the view handled the hover event.

### onKeyDown

    public boolean onKeyDown (int keyCode,
                    KeyEvent event)

Default implementation of `KeyEvent.Callback#onKeyDown(int, KeyEvent)`: perform press of the view when `KeyEvent#KEYCODE_DPAD_CENTER` or `KeyEvent#KEYCODE_ENTER` is released, if the view is enabled and clickable.

Key presses in software keyboards will generally NOT trigger this listener, although some may elect to do so in some situations. Do not rely on this to catch software key presses.

Parameters
`keyCode` | `int`: a key code that represents the button pressed, from `KeyEvent`
`event` | `KeyEvent`: the KeyEvent object that defines the button action

Returns
`boolean` | If you handled the event, return true. If you want to allow the event to be handled by the next receiver, return false.

### onKeyMultiple

    public boolean onKeyMultiple (int keyCode,
                    int repeatCount,
                    KeyEvent event)

Default implementation of `KeyEvent.Callback#onKeyMultiple(int, int, KeyEvent)`: always returns false (doesn't handle the event).

Key presses in software keyboards will generally NOT trigger this listener, although some may elect to do so in some situations. Do not rely on this to catch software key presses.

Parameters
`keyCode` | `int`: A key code that represents the button pressed, from `KeyEvent`.
`repeatCount` | `int`: The number of times the action was made.
`event` | `KeyEvent`: The KeyEvent object that defines the button action.

Returns
`boolean` | If you handled the event, return true. If you want to allow the event to be handled by the next receiver, return false.

### onKeyUp

    public boolean onKeyUp (int keyCode,
                    KeyEvent event)

Default implementation of `KeyEvent.Callback#onKeyUp(int, KeyEvent)`: perform clicking of the view when `KeyEvent#KEYCODE_DPAD_CENTER`, `KeyEvent#KEYCODE_ENTER` or `KeyEvent#KEYCODE_SPACE` is released.

Key presses in software keyboards will generally NOT trigger this listener, although some may elect to do so in some situations. Do not rely on this to catch software key presses.

Parameters
`keyCode` | `int`: A key code that represents the button pressed, from `KeyEvent`.
`event` | `KeyEvent`: The KeyEvent object that defines the button action.

Returns
`boolean` | If you handled the event, return true. If you want to allow the event to be handled by the next receiver, return false.

### onPause

    public void onPause ()

Does a best-effort attempt to pause any processing that can be paused safely, such as animations and geolocation. Note that this call does not pause JavaScript. To pause JavaScript globally, use `pauseTimers()`. To resume WebView, call `onResume()`.

### onProvideAutofillVirtualStructure

    public void onProvideAutofillVirtualStructure (ViewStructure structure,
                    int flags)

Populates a `ViewStructure` containing virtual children to fullfil an autofill request.

This method should be used when the view manages a virtual structure under this view. For example, a view that draws input fields using `draw(android.graphics.Canvas)`.

When implementing this method, subclasses must follow the rules below:

- Add virtual children by calling the `ViewStructure#newChild(int)` or `ViewStructure#asyncNewChild(int)` methods, where the `id` is an unique id identifying the children in the virtual structure.
- The children hierarchy can have multiple levels if necessary, but ideally it should exclude intermediate levels that are irrelevant for autofill; that would improve the autofill performance.
- Also implement `autofill(android.util.SparseArray)` to autofill the virtual children.
- Set the autofill properties of the child structure as defined by `onProvideAutofillStructure(android.view.ViewStructure, int)`, using `ViewStructure#setAutofillId(AutofillId, int)` to set its autofill id.
- Call `AutofillManager.notifyViewEntered(View, int, Rect)` and/or `AutofillManager.notifyViewExited(View, int)` when the focused virtual child changed.
- Override `isVisibleToUserForAutofill(int)` to allow the platform to query whether a given virtual view is visible to the user in order to support triggering save when all views of interest go away.
- Call `AutofillManager.notifyValueChanged(View, int, AutofillValue)` when the value of a virtual child changed.
- Call `AutofillManager.notifyViewVisibilityChanged(View, int, boolean)` when the visibility of a virtual child changed.
- Call `AutofillManager.notifyViewClicked(View, int)` when a virtual child is clicked.
- Call `AutofillManager#commit()` when the autofill context of the view structure changed and the current context should be committed (for example, when the user tapped a `SUBMIT` button in an HTML page).
- Call `AutofillManager#cancel()` when the autofill context of the view structure changed and the current context should be canceled (for example, when the user tapped a `CANCEL` button in an HTML page).
- Provide ways for users to manually request autofill by calling `AutofillManager#requestAutofill(View, int, Rect)`.
- The `left` and `top` values set in `ViewStructure#setDimens(int, int, int, int, int, int)` must be relative to the next `ViewGroup#isImportantForAutofill()` predecessor view included in the structure.

Views with virtual children support the Autofill Framework mainly by:

- Providing the metadata defining what the virtual children mean and how they can be autofilled.
- Implementing the methods that autofill the virtual children.

This method is responsible for the former; `autofill(android.util.SparseArray)` is responsible for the latter.

The `ViewStructure` traditionally represents a `View`, while for web pages it represent HTML nodes. Hence, it's necessary to "map" the HTML properties in a way that is understood by the `AutofillService` implementations:

1. Only the HTML nodes inside a `FORM` are generated.
2. The source of the HTML is set using `ViewStructure#setWebDomain(String)` in the node representing the WebView.
3. If a web page has multiple `FORM`s, only the data for the current form is represented—if the user taps a field from another form, then the current autofill context is canceled (by calling `AutofillManager.cancel()` and a new context is created for that `FORM`.
4. Similarly, if the page has `IFRAME` nodes, they are not initially represented in the view structure until the user taps a field from a `FORM` inside the `IFRAME`, in which case it would be treated the same way as multiple forms described above, except that the `ViewStructure#setWebDomain(String)` of the `FORM` contains the `src` attribute from the `IFRAME` node.
5. The W3C autofill field (`autocomplete` tag attribute) maps to `ViewStructure#setAutofillHints(String[])`.
6. If the view is editable, the `ViewStructure#setAutofillType(int)` and `ViewStructure#setAutofillValue(AutofillValue)` must be set.
7. The `placeholder` attribute maps to `ViewStructure#setHint(CharSequence)`.
8. Other HTML attributes can be represented through `ViewStructure#setHtmlInfo(android.view.ViewStructure.HtmlInfo)`.

If the WebView implementation can determine that the value of a field was set statically (for example, not through Javascript), it should also call `structure.setDataIsSensitive(false)`.

For example, an HTML form with 2 fields for username and password:

        <label>Username:</label>
        <input type="text" name="username" id="user" value="Type your username" autocomplete="username" placeholder="Email or username">
        <label>Password:</label>
        <input type="password" name="password" id="pass" autocomplete="current-password" placeholder="Password">

Would map to:

         int index = structure.addChildCount(2);
         ViewStructure username = structure.newChild(index);
         username.setAutofillId(structure.getAutofillId(), 1); // id 1 - first child
         username.setAutofillHints("username");
         username.setHtmlInfo(username.newHtmlInfoBuilder("input")
             .addAttribute("type", "text")
             .addAttribute("name", "username")
             .addAttribute("label", "Username:")
             .build());
         username.setHint("Email or username");
         username.setAutofillType(View.AUTOFILL_TYPE_TEXT);
         username.setAutofillValue(AutofillValue.forText("Type your username"));
         // Value of the field is not sensitive because it was created statically and not changed.
         username.setDataIsSensitive(false);

         ViewStructure password = structure.newChild(index + 1);
         username.setAutofillId(structure, 2); // id 2 - second child
         password.setAutofillHints("current-password");
         password.setHtmlInfo(password.newHtmlInfoBuilder("input")
             .addAttribute("type", "password")
             .addAttribute("name", "password")
             .addAttribute("label", "Password:")
             .build());
         password.setHint("Password");
         password.setAutofillType(View.AUTOFILL_TYPE_TEXT);

Parameters
`structure` | `ViewStructure`: fill in with virtual children data for autofill purposes.
`flags` | `int`: optional flags.

### onProvideContentCaptureStructure

    public void onProvideContentCaptureStructure (ViewStructure structure,
                    int flags)

Populates a `ViewStructure` for content capture.

This method is called after a view is that is eligible for content capture (for example, if it `isImportantForAutofill()`, an intelligence service is enabled for the user, and the activity rendering the view is enabled for content capture) is laid out and is visible.

The populated structure is then passed to the service through `ContentCaptureSession#notifyViewAppeared(ViewStructure)`.

Note: views that manage a virtual structure under this view must populate just the node representing this view and return right away, then asynchronously report (not necessarily in the UI thread) when the children nodes appear, disappear or have their text changed by calling `ContentCaptureSession#notifyViewAppeared(ViewStructure)`, `ContentCaptureSession#notifyViewDisappeared(AutofillId)`, and `ContentCaptureSession#notifyViewTextChanged(AutofillId, CharSequence)` respectively. The structure for the a child must be created using `ContentCaptureSession#newVirtualViewStructure(AutofillId, long)`, and the `autofillId` for a child can be obtained either through `childStructure.getAutofillId()` or `ContentCaptureSession#newAutofillId(AutofillId, long)`.

When the virtual view hierarchy represents a web page, you should also:

- Call `ContentCaptureManager#getContentCaptureConditions()` to infer content capture events should be generate for that URL.
- Create a new `ContentCaptureSession` child for every HTML element that renders a new URL (like an `IFRAME`) and use that session to notify events from that subtree.

Note: the following methods of the `structure` will be ignored:

- `ViewStructure#setChildCount(int)`
- `ViewStructure#addChildCount(int)`
- `ViewStructure#getChildCount()`
- `ViewStructure#newChild(int)`
- `ViewStructure#asyncNewChild(int)`
- `ViewStructure#asyncCommit()`
- `ViewStructure#setWebDomain(String)`
- `ViewStructure#newHtmlInfoBuilder(String)`
- `ViewStructure#setHtmlInfo(android.view.ViewStructure.HtmlInfo)`
- `ViewStructure#setDataIsSensitive(boolean)`
- `ViewStructure#setAlpha(float)`
- `ViewStructure#setElevation(float)`
- `ViewStructure#setTransformation(Matrix)`

Parameters
`structure` | `ViewStructure`: This value cannot be `null`.
`flags` | `int`

### onProvideVirtualStructure

    public void onProvideVirtualStructure (ViewStructure structure)

Called when assist structure is being retrieved from a view as part of `Activity.onProvideAssistData` to generate additional virtual structure under this view. The defaullt implementation uses `getAccessibilityNodeProvider()` to try to generate this from the view's virtual accessibility nodes, if any. You can override this for a more optimal implementation providing this data.

Parameters
`structure` | `ViewStructure`

### onResume

    public void onResume ()

Resumes a WebView after a previous call to `onPause()`.

### onStartTemporaryDetach

    public void onStartTemporaryDetach ()

This is called when a container is going to temporarily detach a child, with `ViewGroup#detachViewFromParent(View)`. It will either be followed by `onFinishTemporaryDetach()` or `onDetachedFromWindow()` when the container is done.

### onTouchEvent

    public boolean onTouchEvent (MotionEvent event)

Implement this method to handle touch screen motion events.

If this method is used to detect click actions, it is recommended that the actions be performed by implementing and calling `performClick()`. This will ensure consistent system behavior, including:

- obeying click sound preferences
- dispatching OnClickListener calls
- handling `AccessibilityNodeInfo#ACTION_CLICK` when accessibility features are enabled

Parameters
`event` | `MotionEvent`: The motion event.

Returns
`boolean` | True if the event was handled, false otherwise.

### onTrackballEvent

    public boolean onTrackballEvent (MotionEvent event)

Implement this method to handle trackball motion events. The relative movement of the trackball since the last event can be retrieve with `MotionEvent#getX` and `MotionEvent#getY`. These are normalized so that a movement of 1 corresponds to the user pressing one DPAD key (so they will often be fractional values, representing the more fine-grained movement information available from a trackball).

Parameters
`event` | `MotionEvent`: The motion event.

Returns
`boolean` | True if the event was handled, false otherwise.

### onWindowFocusChanged

    public void onWindowFocusChanged (boolean hasWindowFocus)

Called when the window containing this view gains or loses focus. Note that this is separate from view focus: to receive key events, both your view and its window must have focus. If a window is displayed on top of yours that takes input focus, then your own window will lose focus but the view focus will remain unchanged.

Parameters
`hasWindowFocus` | `boolean`: True if the window containing this view now has focus, false otherwise.

### overlayHorizontalScrollbar

    public boolean overlayHorizontalScrollbar ()

This method is deprecated.
This method is now obsolete.

Gets whether horizontal scrollbar has overlay style.

Returns
`boolean` | `true`

### overlayVerticalScrollbar

    public boolean overlayVerticalScrollbar ()

This method is deprecated.
This method is now obsolete.

Gets whether vertical scrollbar has overlay style.

Returns
`boolean` | `false`

### pageDown

    public boolean pageDown (boolean bottom)

Scrolls the contents of this WebView down by half the page size.

Parameters
`bottom` | `boolean`: `true` to jump to bottom of page

Returns
`boolean` | `true` if the page was scrolled

### pageUp

    public boolean pageUp (boolean top)

Scrolls the contents of this WebView up by half the view size.

Parameters
`top` | `boolean`: `true` to jump to the top of the page

Returns
`boolean` | `true` if the page was scrolled

### pauseTimers

    public void pauseTimers ()

Pauses all layout, parsing, and JavaScript timers for all WebViews. This is a global requests, not restricted to just this WebView. This can be useful if the application has been paused.

### performLongClick

    public boolean performLongClick ()

Calls this view's OnLongClickListener, if it is defined. Invokes the context menu if the OnLongClickListener did not consume the event.

Returns
`boolean` | `true` if one of the above receivers consumed the event, `false` otherwise

### postUrl

    public void postUrl (String url,
                    byte[] postData)

Loads the URL with postData using "POST" method into this WebView. If url is not a network URL, it will be loaded with `loadUrl(java.lang.String)` instead, ignoring the postData param.

Parameters
`url` | `String`: the URL of the resource to load This value cannot be `null`.
`postData` | `byte`: the data will be passed to "POST" request, which must be be "application/x-www-form-urlencoded" encoded. This value cannot be `null`.

### postVisualStateCallback

    public void postVisualStateCallback (long requestId,
                    WebView.VisualStateCallback callback)

Posts a `VisualStateCallback`, which will be called when the current state of the WebView is ready to be drawn.

Because updates to the DOM are processed asynchronously, updates to the DOM may not immediately be reflected visually by subsequent `WebView#onDraw` invocations. The `VisualStateCallback` provides a mechanism to notify the caller when the contents of the DOM at the current time are ready to be drawn the next time the `WebView` draws.

The next draw after the callback completes is guaranteed to reflect all the updates to the DOM up to the point at which the `VisualStateCallback` was posted, but it may also contain updates applied after the callback was posted.

The state of the DOM covered by this API includes the following:

- primitive HTML elements (div, img, span, etc..)
- images
- CSS animations
- WebGL
- canvas

It does not include the state of:

- the video tag

To guarantee that the `WebView` will successfully render the first frame after the `VisualStateCallback#onComplete` method has been called a set of conditions must be met:

- If the `WebView`'s visibility is set to `View#VISIBLE` then the `WebView` must be attached to the view hierarchy.
- If the `WebView`'s visibility is set to `View#INVISIBLE` then the `WebView` must be attached to the view hierarchy and must be made `View#VISIBLE` from the `VisualStateCallback#onComplete` method.
- If the `WebView`'s visibility is set to `View#GONE` then the `WebView` must be attached to the view hierarchy and its `AbsoluteLayout.LayoutParams`'s width and height need to be set to fixed values and must be made `View#VISIBLE` from the `VisualStateCallback#onComplete` method.

When using this API it is also recommended to enable pre-rasterization if the `WebView` is off screen to avoid flickering. See `WebSettings#setOffscreenPreRaster` for more details and do consider its caveats.

Parameters
`requestId` | `long`: An id that will be returned in the callback to allow callers to match requests with callbacks.
`callback` | `WebView.VisualStateCallback`: The callback to be invoked. This value cannot be `null`.

### postWebMessage

    public void postWebMessage (WebMessage message,
                    Uri targetOrigin)

Post a message to main frame. The embedded application can restrict the messages to a certain target origin. See HTML5 spec for how target origin can be used.

A target origin can be set as a wildcard ("*"). However this is not recommended. See the page above for security issues.

Content loaded via `loadData(java.lang.String, java.lang.String, java.lang.String)` will not have a valid origin, and thus cannot be sent messages securely. If you need to send messages using this function, you should use `loadDataWithBaseURL(java.lang.String, java.lang.String, java.lang.String, java.lang.String, java.lang.String)` with a valid HTTP or HTTPS `baseUrl` to define a valid origin that can be used for messaging.

Parameters
`message` | `WebMessage`: the WebMessage This value cannot be `null`.
`targetOrigin` | `Uri`: the target origin. This value cannot be `null`.

### reload

    public void reload ()

Reloads the current URL.

### removeJavascriptInterface

    public void removeJavascriptInterface (String name)

Removes a previously injected Java object from this WebView. Note that the removal will not be reflected in JavaScript until the page is next (re)loaded. See `addJavascriptInterface(Object, String)`.

Parameters
`name` | `String`: the name used to expose the object in JavaScript This value cannot be `null`.

### requestChildRectangleOnScreen

    public boolean requestChildRectangleOnScreen (View child,
                    Rect rect,
                    boolean immediate)

Called when a child of this group wants a particular rectangle to be positioned onto the screen. `ViewGroup`s overriding this can trust that:

- child will be a direct child of this group
- rectangle will be in the child's content coordinates

`ViewGroup`s overriding this should uphold the contract:

- nothing will change if the rectangle is already visible
- the view port will be scrolled only just enough to make the rectangle visible

Parameters
`child` | `View`: The direct child making the request.
`rect` | `Rect`: The rectangle in the child's coordinates the child wishes to be on the screen.
`immediate` | `boolean`: True to forbid animated or delayed scrolling, false otherwise

Returns
`boolean` | Whether the group scrolled to handle the operation

### requestFocus

    public boolean requestFocus (int direction,
                    Rect previouslyFocusedRect)

Call this to try to give focus to a specific view or to one of its descendants and give it hints about the direction and a specific rectangle that the focus is coming from. The rectangle can help give larger views a finer grained hint about where focus is coming from, and therefore, where to show selection, or forward focus change internally. A view will not actually take focus if it is not focusable (`isFocusable()` returns false), or if it is focusable and it is not focusable in touch mode (`isFocusableInTouchMode()`) while the device is in touch mode. A View will not take focus if it is not visible. A View will not take focus if one of its parents has `ViewGroup.getDescendantFocusability()` equal to `ViewGroup#FOCUS_BLOCK_DESCENDANTS`. See also `focusSearch(int)`, which is what you call to say that you have focus, and you want your parent to look for the next one. You may wish to override this method if your custom `View` has an internal `View` that it wishes to forward the request to. Looks for a view to give focus to respecting the setting specified by `getDescendantFocusability()`. Uses `onRequestFocusInDescendants(int, android.graphics.Rect)` to find focus within the children of this group when appropriate.

Parameters
`direction` | `int`: One of FOCUS_UP, FOCUS_DOWN, FOCUS_LEFT, and FOCUS_RIGHT
`previouslyFocusedRect` | `Rect`: The rectangle (in this View's coordinate system) to give a finer grained hint about where focus is coming from. May be null if there is no hint.

Returns
`boolean` | Whether this view or one of its descendants actually took focus.

### requestFocusNodeHref

    public void requestFocusNodeHref (Message hrefMsg)

Requests the anchor or image element URL at the last tapped point. If hrefMsg is `null`, this method returns immediately and does not dispatch hrefMsg to its target. If the tapped point hits an image, an anchor, or an image in an anchor, the message associates strings in named keys in its data. The value paired with the key may be an empty string.

Parameters
`hrefMsg` | `Message`: the message to be dispatched with the result of the request. The message data contains three keys. "url" returns the anchor's href attribute. "title" returns the anchor's text. "src" returns the image's src attribute. This value may be `null`.

### requestImageRef

    public void requestImageRef (Message msg)

Requests the URL of the image last touched by the user. msg will be sent to its target with a String representing the URL as its object.

Parameters
`msg` | `Message`: the message to be dispatched with the result of the request as the data member with "url" as key. The result can be `null`. This value cannot be `null`.

### restoreState

    public WebBackForwardList restoreState (Bundle inState)

Restores the state of this WebView from the given Bundle. This method is intended for use in `Activity.onRestoreInstanceState(Bundle)` and should be called to restore the state of this WebView. If it is called after this WebView has had a chance to build state (load pages, create a back/forward list, etc.) there may be undesirable side-effects. Please note that this method no longer restores the display data for this WebView.

Parameters
`inState` | `Bundle`: the incoming Bundle of state This value cannot be `null`.

Returns
`WebBackForwardList` | the restored back/forward list or `null` if restoreState failed

### resumeTimers

### savePassword

    public void savePassword (String host,
                    String username,
                    String password)

This method is deprecated.
Saving passwords in WebView will not be supported in future versions.

Sets a username and password pair for the specified host. This data is used by the WebView to autocomplete username and password fields in web forms. Note that this is unrelated to the credentials used for HTTP authentication.

Parameters
`host` | `String`: the host that required the credentials
`username` | `String`: the username for the given host
`password` | `String`: the password for the given host

See also:

- `WebViewDatabase.clearUsernamePassword()`
- `WebViewDatabase.hasUsernamePassword()`

### saveState

    public WebBackForwardList saveState (Bundle outState)

Saves the state of this WebView used in `Activity.onSaveInstanceState(Bundle)`. Please note that this method no longer stores the display data for this WebView. The previous behavior could potentially leak files if `restoreState(Bundle)` was never called.

Parameters
`outState` | `Bundle`: the Bundle to store this WebView's state This value cannot be `null`.

Returns
`WebBackForwardList` | the same copy of the back/forward list used to save the state, `null` if the method fails.

### saveWebArchive

    public void saveWebArchive (String filename)

Saves the current view as a web archive.

Parameters
`filename` | `String`: the filename where the archive should be placed This value cannot be `null`.

### saveWebArchive

    public void saveWebArchive (String basename,
                    boolean autoname,
                    ValueCallback<String> callback)

Saves the current view as a web archive.

Parameters
`basename` | `String`: the filename where the archive should be placed This value cannot be `null`.
`autoname` | `boolean`: if `false`, takes basename to be a file. If `true`, basename is assumed to be a directory in which a filename will be chosen according to the URL of the current page.
`callback` | `ValueCallback`: called after the web archive has been saved. The parameter for onReceiveValue will either be the filename under which the file was saved, or `null` if saving the file failed. This value may be `null`.

### setBackgroundColor

    public void setBackgroundColor (int color)

Sets the background color for this view.

Parameters
`color` | `int`: the color of the background

### setCertificate

    public void setCertificate (SslCertificate certificate)

This method is deprecated.
Calling this function has no useful effect, and will be ignored in future releases.

Sets the SSL certificate for the main top-level page.

Parameters
`certificate` | `SslCertificate`

### setDataDirectorySuffix

    public static void setDataDirectorySuffix (String suffix)

Define the directory used to store WebView data for the current process. The provided suffix will be used when constructing data and cache directory paths. If this API is not called, no suffix will be used. Each directory can be used by only one process in the application. If more than one process in an app wishes to use WebView, only one process can use the default directory, and other processes must call this API to define a unique suffix.

This means that different processes in the same application cannot directly share WebView-related data, since the data directories must be distinct. Applications that use this API may have to explicitly pass data between processes. For example, login cookies may have to be copied from one process's cookie jar to the other using `CookieManager` if both processes' WebViews are intended to be logged in.

Most applications should simply ensure that all components of the app that rely on WebView are in the same process, to avoid needing multiple data directories. The `disableWebView()` method can be used to ensure that the other processes do not use WebView by accident in this case.

This API must be called before any instances of WebView are created in this process and before any other methods in the android.webkit package are called by this process.

Parameters
`suffix` | `String`: The directory name suffix to be used for the current process. Must not contain a path separator. This value cannot be `null`.

Throws
`IllegalStateException` | if WebView has already been initialized in the current process.
`IllegalArgumentException` | if the suffix contains a path separator.

### setDownloadListener

    public void setDownloadListener (DownloadListener listener)

Registers the interface to be used when content can not be handled by the rendering engine, and should be downloaded instead. This will replace the current handler.

Parameters
`listener` | `DownloadListener`: an implementation of DownloadListener This value may be `null`.

### setFindListener

    public void setFindListener (WebView.FindListener listener)

Registers the listener to be notified as find-on-page operations progress. This will replace the current listener.

Parameters
`listener` | `WebView.FindListener`: an implementation of `FindListener` This value may be `null`.

### setHorizontalScrollbarOverlay

    public void setHorizontalScrollbarOverlay (boolean overlay)

This method is deprecated.
This method has no effect.

Specifies whether the horizontal scrollbar has overlay style.

Parameters
`overlay` | `boolean`: `true` if horizontal scrollbar should have overlay style

### setHttpAuthUsernamePassword

    public void setHttpAuthUsernamePassword (String host,
                    String realm,
                    String username,
                    String password)

This method is deprecated.
Use `WebViewDatabase#setHttpAuthUsernamePassword` instead

Stores HTTP authentication credentials for a given host and realm to the `WebViewDatabase` instance.

Parameters
`host` | `String`: the host to which the credentials apply
`realm` | `String`: the realm to which the credentials apply
`username` | `String`: the username
`password` | `String`: the password

### setInitialScale

    public void setInitialScale (int scaleInPercent)

Sets the initial scale for this WebView. 0 means default. The behavior for the default scale depends on the state of `WebSettings#getUseWideViewPort()` and `WebSettings#getLoadWithOverviewMode()`. If the content fits into the WebView control by width, then the zoom is set to 100%. For wide content, the behavior depends on the state of `WebSettings#getLoadWithOverviewMode()`. If its value is `true`, the content will be zoomed out to be fit by width into the WebView control, otherwise not. If initial scale is greater than 0, WebView starts with this value as initial scale. Please note that unlike the scale properties in the viewport meta tag, this method doesn't take the screen density into account.

Parameters
`scaleInPercent` | `int`: the initial scale in percent

### setLayerType

    public void setLayerType (int layerType,
                    Paint paint)

Specifies the type of layer backing this view. The layer can be `LAYER_TYPE_NONE`, `LAYER_TYPE_SOFTWARE` or `LAYER_TYPE_HARDWARE`.

A layer is associated with an optional `Paint` instance that controls how the layer is composed on screen. The following properties of the paint are taken into account when composing the layer:

- `Translucency (alpha)`
- `Blending mode`
- `Color filter`

If this view has an alpha value set to < 1.0 by calling `setAlpha(float)`, the alpha value of the layer's paint is superseded by this view's alpha value.

Refer to the documentation of `LAYER_TYPE_NONE`, `LAYER_TYPE_SOFTWARE` and `LAYER_TYPE_HARDWARE` for more information on when and how to use layers.

Parameters
`layerType` | `int`: The type of layer to use with this view, must be one of `View.LAYER_TYPE_NONE`, `View.LAYER_TYPE_SOFTWARE` or `View.LAYER_TYPE_HARDWARE` Value is `View.LAYER_TYPE_NONE`, `View.LAYER_TYPE_SOFTWARE`, or `View.LAYER_TYPE_HARDWARE`
`paint` | `Paint`: The paint used to compose the layer. This argument is optional and can be null. It is ignored when the layer type is `View.LAYER_TYPE_NONE` This value may be `null`.

### setLayoutParams

    public void setLayoutParams (ViewGroup.LayoutParams params)

There are many subclasses of ViewGroup.LayoutParams, and these correspond to the different subclasses of ViewGroup that are responsible for arranging their children.

Parameters
`params` | `ViewGroup.LayoutParams`: The layout parameters for this view, cannot be null

### setMapTrackballToArrowKeys

    public void setMapTrackballToArrowKeys (boolean setMap)

This method is deprecated.
Only the default case, `true`, will be supported in a future version.

Parameters
`setMap` | `boolean`

### setNetworkAvailable

    public void setNetworkAvailable (boolean networkUp)

Informs WebView of the network state. This is used to set the JavaScript property window.navigator.isOnline and generates the online/offline event as specified in HTML5, sec. 5.7.7

Parameters
`networkUp` | `boolean`: a boolean indicating if network is available

### setOverScrollMode

    public void setOverScrollMode (int mode)

Set the over-scroll mode for this view. Valid over-scroll modes are `OVER_SCROLL_ALWAYS`, `OVER_SCROLL_IF_CONTENT_SCROLLS` (allow over-scrolling only if the view content is larger than the container), or `OVER_SCROLL_NEVER`. Setting the over-scroll mode of a view will have an effect only if the view is capable of scrolling.

Parameters
`mode` | `int`: The new over-scroll mode for this view.

### setPictureListener

    public void setPictureListener (WebView.PictureListener listener)

This method is deprecated.
This method is now obsolete.

Sets the Picture listener. This is an interface used to receive notifications of a new Picture.

Parameters
`listener` | `WebView.PictureListener`: an implementation of WebView.PictureListener

### setRendererPriorityPolicy

    public void setRendererPriorityPolicy (int rendererRequestedPriority,
                    boolean waivedWhenNotVisible)

Set the renderer priority policy for this `WebView`. The priority policy will be used to determine whether an out of process renderer should be considered to be a target for OOM killing. Because a renderer can be associated with more than one WebView, the final priority it is computed as the maximum of any attached WebViews. When a WebView is destroyed it will cease to be considerered when calculating the renderer priority. Once no WebViews remain associated with the renderer, the priority of the renderer will be reduced to `RENDERER_PRIORITY_WAIVED`. The default policy is to set the priority to `RENDERER_PRIORITY_IMPORTANT` regardless of visibility, and this should not be changed unless the caller also handles renderer crashes with `WebViewClient#onRenderProcessGone`. Any other setting will result in WebView renderers being killed by the system more aggressively than the application.

Parameters
`rendererRequestedPriority` | `int`: the minimum priority at which this WebView desires the renderer process to be bound. Value is `RENDERER_PRIORITY_WAIVED`, `RENDERER_PRIORITY_BOUND`, or `RENDERER_PRIORITY_IMPORTANT`
`waivedWhenNotVisible` | `boolean`: if `true`, this flag specifies that when this WebView is not visible, it will be treated as if it had requested a priority of `RENDERER_PRIORITY_WAIVED`.

### setSafeBrowsingWhitelist

    public static void setSafeBrowsingWhitelist (List<String> hosts,
                    ValueCallback<Boolean> callback)

Sets the list of hosts (domain names/IP addresses) that are exempt from SafeBrowsing checks. The list is global for all the WebViews.

Each rule should take one of these:

Rule | Example | Matches Subdomain
--- | --- | ---
HOSTNAME | example.com | Yes
.HOSTNAME | .example.com | No
IPV4_LITERAL | 192.168.1.1 | No
IPV6_LITERAL_WITH_BRACKETS | [10:20:30:40:50:60:70:80] | No

All other rules, including wildcards, are invalid.

The correct syntax for hosts is defined by RFC 3986.

Parameters
`hosts` | `List`: the list of hosts This value cannot be `null`.
`callback` | `ValueCallback`: will be called with `true` if hosts are successfully added to the whitelist. It will be called with `false` if any hosts are malformed. The callback will be run on the UI thread This value may be `null`.

### setScrollBarStyle

    public void setScrollBarStyle (int style)

Specify the style of the scrollbars. The scrollbars can be overlaid or inset. When inset, they add to the padding of the view. And the scrollbars can be drawn inside the padding area or on the edge of the view. For example, if a view has a background drawable and you want to draw the scrollbars inside the padding specified by the drawable, you can use SCROLLBARS_INSIDE_OVERLAY or SCROLLBARS_INSIDE_INSET. If you want them to appear at the edge of the view, ignoring the padding, then you can use SCROLLBARS_OUTSIDE_OVERLAY or SCROLLBARS_OUTSIDE_INSET.

Parameters
`style` | `int`: the style of the scrollbars. Should be one of SCROLLBARS_INSIDE_OVERLAY, SCROLLBARS_INSIDE_INSET, SCROLLBARS_OUTSIDE_OVERLAY or SCROLLBARS_OUTSIDE_INSET.

This flag can be enabled in order to facilitate debugging of web layouts and JavaScript code running inside WebViews. Please refer to WebView documentation for the debugging guide. The default is `false`.

Parameters
`enabled` | `boolean`: whether to enable web contents debugging

### setWebViewClient

    public void setWebViewClient (WebViewClient client)

- `getWebViewClient()`

### setWebViewRenderProcessClient

    public void setWebViewRenderProcessClient (Executor executor,
                    WebViewRenderProcessClient webViewRenderProcessClient)

Sets the renderer client object associated with this WebView.

The renderer client encapsulates callbacks relevant to WebView renderer state. See `WebViewRenderProcessClient` for details.

Although many WebView instances may share a single underlying renderer, and renderers may live either in the application process, or in a sandboxed process that is isolated from the application process, instances of `WebViewRenderProcessClient` are set per-WebView. Callbacks represent renderer events from the perspective of this WebView, and may or may not be correlated with renderer events affecting other WebViews.

Parameters
`executor` | `Executor`: the Executor on which `WebViewRenderProcessClient` callbacks will execute. This value cannot be `null`. Callback and listener events are dispatched through this `Executor`, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use `Context.getMainExecutor()`. To dispatch events through a shared thread pool, you can use `AsyncTask#THREAD_POOL_EXECUTOR`.
`webViewRenderProcessClient` | `WebViewRenderProcessClient`: the `WebViewRenderProcessClient` object. This value cannot be `null`.

### setWebViewRenderProcessClient

    public void setWebViewRenderProcessClient (WebViewRenderProcessClient webViewRenderProcessClient)

Sets the renderer client object associated with this WebView. See `setWebViewRenderProcessClient(java.util.concurrent.Executor, android.webkit.WebViewRenderProcessClient)` for details.

`WebViewRenderProcessClient` callbacks will run on the thread that this WebView was initialized on.

Parameters
`webViewRenderProcessClient` | `WebViewRenderProcessClient`: the `WebViewRenderProcessClient` object. This value may be `null`.

### shouldDelayChildPressedState

    public boolean shouldDelayChildPressedState ()

Return true if the pressed state should be delayed for children or descendants of this ViewGroup. Generally, this should be done for containers that can scroll, such as a List. This prevents the pressed state from appearing when the user is actually trying to scroll the content. The default implementation returns true for compatibility reasons. Subclasses that do not scroll should generally override this method and return false.

Returns
`boolean` |

### showFindDialog

    public boolean showFindDialog (String text,
                    boolean showIme)

This method is deprecated.
This method does not work reliably on all Android versions; implementing a custom find dialog using WebView.findAllAsync() provides a more robust solution.

Starts an ActionMode for finding text in this WebView. Only works if this WebView is attached to the view system.

Parameters
`text` | `String`: if non-null, will be the initial text to search for. Otherwise, the last String searched for in this WebView will be used to start. This value may be `null`.
`showIme` | `boolean`: if `true`, show the IME, assuming the user will begin typing. If `false` and text is non-null, perform a find all.

Returns
`boolean` | `true` if the find dialog is shown, `false` otherwise

### startSafeBrowsing

    public static void startSafeBrowsing (Context context,
                    ValueCallback<Boolean> callback)

Starts Safe Browsing initialization.

URL loads are not guaranteed to be protected by Safe Browsing until after `callback` is invoked with `true`. Safe Browsing is not fully supported on all devices. For those devices `callback` will receive `false`.

This should not be called if Safe Browsing has been disabled by manifest tag or `WebSettings#setSafeBrowsingEnabled`. This prepares resources used for Safe Browsing.

This should be called with the Application Context (and will always use the Application context to do its work regardless).

Parameters
`context` | `Context`: Application Context. This value cannot be `null`.
`callback` | `ValueCallback`: will be called on the UI thread with `true` if initialization is successful, `false` otherwise. This value may be `null`.

### stopLoading

    public void stopLoading ()

Stops the current load.

### zoomBy

    public void zoomBy (float zoomFactor)

Performs a zoom operation in this WebView.

Parameters
`zoomFactor` | `float`: the zoom factor to apply. The zoom factor will be clamped to the WebView's zoom limits. This value must be in the range 0.01 to 100.0 inclusive.

### zoomIn

    public boolean zoomIn ()

Performs zoom in in this WebView.

Returns
`boolean` | `true` if zoom in succeeds, `false` if no zoom changes

### zoomOut

    public boolean zoomOut ()

Performs zoom out in this WebView.

Returns
`boolean` | `true` if zoom out succeeds, `false` if no zoom changes

## Protected methods

`int` | the total vertical range represented by the vertical scrollbar The default range is the drawing height of this view.

### dispatchDraw

    protected void dispatchDraw (Canvas canvas)

Called by draw to draw the child views. This may be overridden by derived classes to gain control just before its children are drawn (but after its own view has been drawn).

Parameters
`canvas` | `Canvas`: the canvas on which to draw the view

### onAttachedToWindow

    protected void onAttachedToWindow ()

This is called when the view is attached to a window. At this point it has a Surface and will start drawing. Note that this function is guaranteed to be called before `onDraw(android.graphics.Canvas)`, however it may be called any time before the first onDraw -- including before or after `onMeasure(int, int)`.
If you override this method you must call through to the superclass implementation.

### onConfigurationChanged

    protected void onConfigurationChanged (Configuration newConfig)

Called when the current configuration of the resources being used by the application have changed. You can use this to decide when to reload resources that can changed based on orientation and other configuration characteristics. You only need to use this if you are not relying on the normal `Activity` mechanism of recreating the activity instance upon a configuration change.

Parameters
`newConfig` | `Configuration`: The new resource configuration.

### onDraw

    protected void onDraw (Canvas canvas)

Implement this to do your drawing.

Parameters
`canvas` | `Canvas`: the canvas on which the background will be drawn

### onFocusChanged

    protected void onFocusChanged (boolean focused,
                    int direction,
                    Rect previouslyFocusedRect)

Called by the view system when the focus state of this view changes. When the focus change event is caused by directional navigation, direction and previouslyFocusedRect provide insight into where the focus is coming from. When overriding, be sure to call up through to the super class so that the standard focus handling will occur.
If you override this method you must call through to the superclass implementation.

Parameters
`focused` | `boolean`: True if the View has focus; false otherwise.
`direction` | `int`: The direction focus has moved when requestFocus() is called to give this view focus. Values are `View.FOCUS_UP`, `View.FOCUS_DOWN`, `View.FOCUS_LEFT`, `View.FOCUS_RIGHT`, `View.FOCUS_FORWARD`, or `View.FOCUS_BACKWARD`. It may not always apply, in which case use the default. Value is `View.FOCUS_BACKWARD`, `View.FOCUS_FORWARD`, `View.FOCUS_LEFT`, `View.FOCUS_UP`, `View.FOCUS_RIGHT`, or `View.FOCUS_DOWN`
`previouslyFocusedRect` | `Rect`: The rectangle, in this view's coordinate system, of the previously focused view. If applicable, this will be passed in as finer grained information about where the focus is coming from (in addition to direction). Will be `null` otherwise. This value may be `null`.

### onMeasure

    protected void onMeasure (int widthMeasureSpec,
                    int heightMeasureSpec)

Measure the view and its content to determine the measured width and the measured height. This method is invoked by `measure(int, int)` and should be overridden by subclasses to provide accurate and efficient measurement of their contents.

CONTRACT: When overriding this method, you must call `setMeasuredDimension(int, int)` to store the measured width and height of this view. Failure to do so will trigger an `IllegalStateException`, thrown by `measure(int, int)`. Calling the superclass' `onMeasure(int, int)` is a valid use.

The base class implementation of measure defaults to the background size, unless a larger size is allowed by the MeasureSpec. Subclasses should override `onMeasure(int, int)` to provide better measurements of their content.

If this method is overridden, it is the subclass's responsibility to make sure the measured height and width are at least the view's minimum height and width (`getSuggestedMinimumHeight()` and `getSuggestedMinimumWidth()`).

Parameters
`widthMeasureSpec` | `int`: horizontal space requirements as imposed by the parent. The requirements are encoded with `View.MeasureSpec`.
`heightMeasureSpec` | `int`: vertical space requirements as imposed by the parent. The requirements are encoded with `View.MeasureSpec`.

### onOverScrolled

    protected void onOverScrolled (int scrollX,
                    int scrollY,
                    boolean clampedX,
                    boolean clampedY)

Called by `overScrollBy(int, int, int, int, int, int, int, int, boolean)` to respond to the results of an over-scroll operation.

Parameters
`scrollX` | `int`: New X scroll value in pixels
`scrollY` | `int`: New Y scroll value in pixels
`clampedX` | `boolean`: True if scrollX was clamped to an over-scroll boundary
`clampedY` | `boolean`: True if scrollY was clamped to an over-scroll boundary

### onScrollChanged

    protected void onScrollChanged (int l,
                    int t,
                    int oldl,
                    int oldt)

This is called in response to an internal scroll in this view (i.e., the view scrolled its own contents). This is typically as a result of `scrollBy(int, int)` or `scrollTo(int, int)` having been called.

Parameters
`l` | `int`: Current horizontal scroll origin.
`t` | `int`: Current vertical scroll origin.
`oldl` | `int`: Previous horizontal scroll origin.
`oldt` | `int`: Previous vertical scroll origin.

### onSizeChanged

    protected void onSizeChanged (int w,
                    int h,
                    int ow,
                    int oh)

This is called during layout when the size of this view has changed. If you were just added to the view hierarchy, you're called with the old values of 0.

Parameters
`w` | `int`: Current width of this view.
`h` | `int`: Current height of this view.
`ow` | `int`: Old width of this view.
`oh` | `int`: Old height of this view.

### onVisibilityChanged

    protected void onVisibilityChanged (View changedView,
                    int visibility)

Called when the visibility of the view or an ancestor of the view has changed.

Parameters
`changedView` | `View`: The view whose visibility changed. May be `this` or an ancestor view. This value cannot be `null`.
`visibility` | `int`: The new visibility, one of `View.VISIBLE`, `View.INVISIBLE` or `View.GONE`. Value is `View.VISIBLE`, `View.INVISIBLE`, or `View.GONE`

### onWindowVisibilityChanged

    protected void onWindowVisibilityChanged (int visibility)

Called when the window containing has change its visibility (between `GONE`, `INVISIBLE`, and `VISIBLE`). Note that this tells you whether or not your window is being made visible to the window manager; this does not tell you whether or not your window is obscured by other windows on the screen, even if it is itself visible.

Parameters
`visibility` | `int`: The new visibility of the window. Value is `View.VISIBLE`, `View.INVISIBLE`, or `View.GONE`
