## XML attributes

### android:disableDependentsState

The state (true for on, or false for off) that causes dependents to be disabled. By default, dependents will be disabled when this is unchecked, so the value of this preference is false.

May be a boolean value, such as "`true`" or "`false`".

### android:summaryOff

The summary for the Preference in a PreferenceActivity screen when the CheckBoxPreference is unchecked. If separate on/off summaries are not needed, the summary attribute can be used instead.

May be a string value, using '\\;' to escape characters such as '\\n' or '\\uxxxx' for a unicode character;

### android:summaryOn

The summary for the Preference in a PreferenceActivity screen when the CheckBoxPreference is checked. If separate on/off summaries are not needed, the summary attribute can be used instead.

May be a string value, using '\\;' to escape characters such as '\\n' or '\\uxxxx' for a unicode character;

## Protected methods

### onBindView

    protected void onBindView (View view)

Binds the created View to the data for this Preference.

This is a good place to grab references to custom Views in the layout and set properties on them.
