Remarks

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.

<ul> <li>The view receives a hover event with action MotionEvent#ACTION_HOVER_ENTER when the pointer enters the bounds of the view.</li> <li>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.</li> <li>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.</li> </ul>

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 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.
