/**
 * This is where a View should populate outgoing accessibility events with its text content.
 * While this method is free to modify event attributes other than text content, doing so
 * should normally be performed in
 * {@link #onInitializeAccessibilityEvent(android.view.accessibility.AccessibilityEvent)}.
 * <p/>
 * <p>Note that the behavior of this method will typically vary, depending on the type of
 * accessibility event is passed into it. The allowed values also very, and are documented
 * in {@link android.view.accessibility.AccessibilityEvent}.
 * <p/>
 * <p>Typically, this is where you'll describe the state of your custom view. You may also
 * want to provide custom directions when the user has focused your view.
 *
 * @param event The accessibility event which to populate.
