Parameters
`canvas` | `Canvas`: The canvas to draw into This value cannot be `null`.

### getAlpha

    public int getAlpha ()

Gets the current alpha value for the drawable. 0 means fully transparent, 255 means fully opaque. This method is implemented by Drawable subclasses and the value returned is specific to how that class treats alpha. The default return value is 255 if the class does not override this method to return a value specific to its use of alpha.

Returns
`int` | Value is between 0 and 255 inclusive

### getChangingConfigurations

    public int getChangingConfigurations ()

Return a mask of the configuration parameters for which this drawable may change, requiring that it be re-created. The default implementation returns whatever was provided through `setChangingConfigurations(int)` or 0 by default. Subclasses may extend this to or in the changing configurations of any other drawables they hold.

Returns
`int` | Value is either `0` or a combination of `ActivityInfo.CONFIG_MCC`, `ActivityInfo.CONFIG_MNC`, `ActivityInfo.CONFIG_LOCALE`, `ActivityInfo.CONFIG_TOUCHSCREEN`, `ActivityInfo.CONFIG_KEYBOARD`, `ActivityInfo.CONFIG_KEYBOARD_HIDDEN`, `ActivityInfo.CONFIG_NAVIGATION`, `ActivityInfo.CONFIG_ORIENTATION`, `ActivityInfo.CONFIG_SCREEN_LAYOUT`, `ActivityInfo.CONFIG_UI_MODE`, `ActivityInfo.CONFIG_SCREEN_SIZE`, `ActivityInfo.CONFIG_SMALLEST_SCREEN_SIZE`, `ActivityInfo.CONFIG_DENSITY`, `ActivityInfo.CONFIG_LAYOUT_DIRECTION`, `ActivityInfo.CONFIG_COLOR_MODE`, and `ActivityInfo.CONFIG_FONT_SCALE`

### getConstantState

    public Drawable.ConstantState getConstantState ()

Return a `ConstantState` instance that holds the shared state of this Drawable.

Returns
`Drawable.ConstantState` | The ConstantState associated to that Drawable. This value may be `null`.

### getCurrent

    public Drawable getCurrent ()

Returns
`Drawable` | The current drawable that will be used by this drawable. For simple drawables, this is just the drawable itself. For drawables that change state like `StateListDrawable` and `LevelListDrawable` this will be the child drawable currently in use. This value cannot be `null`.

### getHotspotBounds

    public void getHotspotBounds (Rect outRect)

Populates `outRect` with the hotspot bounds.

Parameters
`outRect` | `Rect`: the rect to populate with the hotspot bounds This value cannot be `null`.

### getIntrinsicHeight

    public int getIntrinsicHeight ()

Returns the drawable's intrinsic height.

Intrinsic height is the height at which the drawable would like to be laid out, including any inherent padding. If the drawable has no intrinsic height, such as a solid color, this method returns -1.

Returns
`int` | the intrinsic height, or -1 if no intrinsic height

### getIntrinsicWidth

    public int getIntrinsicWidth ()

Returns the drawable's intrinsic width.

Intrinsic width is the width at which the drawable would like to be laid out, including any inherent padding. If the drawable has no intrinsic width, such as a solid color, this method returns -1.

Returns
`int` | the intrinsic width, or -1 if no intrinsic width

### getMinimumHeight

    public int getMinimumHeight ()

Returns the minimum height suggested by this Drawable. If a View uses this Drawable as a background, it is suggested that the View use at least this value for its height. (There will be some scenarios where this will not be possible.) This value should INCLUDE any padding.

Returns
`int` | The minimum height suggested by this Drawable. If this Drawable doesn't have a suggested minimum height, 0 is returned.

### getMinimumWidth

    public int getMinimumWidth ()

Returns the minimum width suggested by this Drawable. If a View uses this Drawable as a background, it is suggested that the View use at least this value for its width. (There will be some scenarios where this will not be possible.) This value should INCLUDE any padding.

Returns
`int` | The minimum width suggested by this Drawable. If this Drawable doesn't have a suggested minimum width, 0 is returned.

### getOpacity

    public int getOpacity ()

This method is deprecated.
This method is no longer used in graphics optimizations

Return the opacity/transparency of this Drawable. The returned value is one of the abstract format constants in `PixelFormat`: `PixelFormat.UNKNOWN`, `PixelFormat.TRANSLUCENT`, `PixelFormat.TRANSPARENT`, or `PixelFormat.OPAQUE`.

An OPAQUE drawable is one that draws all all content within its bounds, completely covering anything behind the drawable. A TRANSPARENT drawable is one that draws nothing within its bounds, allowing everything behind it to show through. A TRANSLUCENT drawable is a drawable in any other state, where the drawable will draw some, but not all, of the content within its bounds and at least some content behind the drawable will be visible. If the visibility of the drawable's contents cannot be determined, the safest/best return value is TRANSLUCENT.

Generally a Drawable should be as conservative as possible with the value it returns. For example, if it contains multiple child drawables and only shows one of them at a time, if only one of the children is TRANSLUCENT and the others are OPAQUE then TRANSLUCENT should be returned. You can use the method `resolveOpacity(int, int)` to perform a standard reduction of two opacities to the appropriate single output.

Note that the returned value does not necessarily take into account a custom alpha or color filter that has been applied by the client through the `setAlpha(int)` or `setColorFilter(ColorFilter)` methods. Some subclasses, such as `BitmapDrawable`, `ColorDrawable`, and `GradientDrawable`, do account for the value of `setAlpha(int)`, but the general behavior is dependent upon the implementation of the subclass.

Returns
`int` | int The opacity class of the Drawable. Value is `PixelFormat.UNKNOWN`, `PixelFormat.TRANSLUCENT`, `PixelFormat.TRANSPARENT`, or `PixelFormat.OPAQUE`

### getOpticalInsets

    public Insets getOpticalInsets ()

Return in insets the layout insets suggested by this Drawable for use with alignment operations during layout.

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

### getOutline

    public void getOutline (Outline outline)

Called to get the drawable to populate the Outline that defines its drawing area.

This method is called by the default `ViewOutlineProvider` to define the outline of the View.

The default behavior defines the outline to be the bounding rectangle of 0 alpha. Subclasses that wish to convey a different shape or alpha value must override this method.

Parameters
`outline` | `Outline`: This value cannot be `null`.

### getPadding

    public boolean getPadding (Rect padding)

Return in padding the insets suggested by this Drawable for placing content inside the drawable's bounds. Positive values move toward the center of the Drawable (set Rect.inset).

Parameters
`padding` | `Rect`: This value cannot be `null`.

Returns
`boolean` | true if this drawable actually has a padding, else false. When false is returned, the padding is always set to 0.

### invalidateDrawable

    public void invalidateDrawable (Drawable who)

Called when the drawable needs to be redrawn. A view at this point should invalidate itself (or at least the part of itself where the drawable appears).

Parameters
`who` | `Drawable`: This value cannot be `null`.

### isAutoMirrored

    public boolean isAutoMirrored ()

Tells if this Drawable will be automatically mirrored when its layout direction is RTL right-to-left. See `LayoutDirection`.

Returns
`boolean` | boolean Returns true if this Drawable will be automatically mirrored.

### isStateful

    public boolean isStateful ()

Indicates whether this drawable will change its appearance based on state. Clients can use this to determine whether it is necessary to calculate their state and call setState.

Returns
`boolean` | True if this drawable changes its appearance based on state, false otherwise.

### jumpToCurrentState

    public void jumpToCurrentState ()

If this Drawable does transition animations between states, ask that it immediately jump to the current state and skip any active animations.

### mutate

    public Drawable mutate ()

Make this drawable mutable. This operation cannot be reversed. A mutable drawable is guaranteed to not share its state with any other drawable. This is especially useful when you need to modify properties of drawables loaded from resources. By default, all drawables instances loaded from the same resource share a common state; if you modify the state of one instance, all the other instances will receive the same modification. Calling this method on a mutable Drawable will have no effect.

Returns
`Drawable` | This drawable. This value cannot be `null`.

### onLayoutDirectionChanged

    public boolean onLayoutDirectionChanged (int layoutDirection)

Called when the drawable's resolved layout direction changes.

Parameters
`layoutDirection` | `int`: Value is `View.LAYOUT_DIRECTION_LTR`, or `View.LAYOUT_DIRECTION_RTL`

Returns
`boolean` | `true` if the layout direction change has caused the appearance of the drawable to change such that it needs to be re-drawn, `false` otherwise

### scheduleDrawable

    public void scheduleDrawable (Drawable who,
                    Runnable what,
                    long when)

A Drawable can call this to schedule the next frame of its animation. An implementation can generally simply call `Handler.postAtTime(Runnable, Object, long)` with the parameters (what, who, when) to perform the scheduling.

Parameters
`who` | `Drawable`: This value cannot be `null`.
`what` | `Runnable`: This value cannot be `null`.
`when` | `long`: The time (in milliseconds) to run. The timebase is `SystemClock.uptimeMillis()`

### selectDrawable

    public boolean selectDrawable (int index)

Sets the currently displayed drawable by index.

If an invalid index is specified, the current drawable will be set to `null` and the index will be set to `-1`.

Parameters
`index` | `int`: the index of the drawable to display

Returns
`boolean` | `true` if the drawable changed, `false` otherwise

### setAlpha

    public void setAlpha (int alpha)

Specify an alpha value for the drawable. 0 means fully transparent, and 255 means fully opaque.

Parameters
`alpha` | `int`: Value is between 0 and 255 inclusive

### setAutoMirrored

    public void setAutoMirrored (boolean mirrored)

Set whether this Drawable is automatically mirrored when its layout direction is RTL (right-to left). See `LayoutDirection`.

Parameters
`mirrored` | `boolean`: Set to true if the Drawable should be mirrored, false if not.

### setColorFilter

    public void setColorFilter (ColorFilter colorFilter)

Specify an optional color filter for the drawable.

If a Drawable has a ColorFilter, each output pixel of the Drawable's drawing contents will be modified by the color filter before it is blended onto the render target of a Canvas.

Pass `null` to remove any existing color filter.

Note: Setting a non-`null` color filter disables `tint`.

Parameters
`colorFilter` | `ColorFilter`: The color filter to apply, or `null` to remove the existing color filter This value may be `null`.

### setDither

    public void setDither (boolean dither)

This method is deprecated.

Parameters
`dither` | `boolean`

### setEnterFadeDuration

    public void setEnterFadeDuration (int ms)

Change the global fade duration when a new drawable is entering the scene.

Parameters
`ms` | `int`: The amount of time to fade in milliseconds.

### setExitFadeDuration

    public void setExitFadeDuration (int ms)

Change the global fade duration when a new drawable is leaving the scene.

Parameters
`ms` | `int`: The amount of time to fade in milliseconds.

### setHotspot

    public void setHotspot (float x,
                    float y)

Specifies the hotspot's location within the drawable.

Parameters
`x` | `float`: The X coordinate of the center of the hotspot

Parameters
`blendMode` | `BlendMode`: This value cannot be `null`.

### setTintList

    public void setTintList (ColorStateList tint)

Specifies tint color for this drawable as a color state list.

A Drawable's drawing content will be blended together with its tint before it is drawn to the screen. This functions similarly to `setColorFilter(int, android.graphics.PorterDuff.Mode)`.

Note: Setting a color filter via `setColorFilter(android.graphics.ColorFilter)` or `setColorFilter(int, android.graphics.PorterDuff.Mode)` overrides tint.

Parameters
`tint` | `ColorStateList`: Color state list to use for tinting this drawable, or `null` to clear the tint This value may be `null`.

### setVisible

    public boolean setVisible (boolean visible,
                    boolean restart)

Parameters
`visible` | `boolean`: Set to true if visible, false if not.
`restart` | `boolean`: You can supply true here to force the drawable to behave as if it has just become visible, even if it had last been set visible. Used for example to force animations to restart.
