title: Listener when hovering view Android
body: <p>The user can draw over view (with a pencil) and i want a listener to know if the user was drawn over other views. When the user is drawing over a view, i want to change the view's color.
  I tried with <code>OnTouchListener</code>, <code>OnHoverListener</code>, <code>OnFocusChangeListener</code> i also tried to override the method <code>onTouchEvent</code>, but none of these were called.</p>
