How to handle an action when a user removes a finger from a button?

Question

I need to handle the action when the user pulls a finger off the button by clicking on it, but does not release it. I tried to use OnTouchListener, but, as I understood it, it only processes the movement of a finger or the release of a button.

Answer 1

It's existing the OnTouchListener also:

view.setOnTouchListener(new View.OnTouchListener() {
   @Override
   public boolean onTouch(View v, MotionEvent event) {
       if(event.getAction() == MotionEvent.ACTION_MOVE) {
           Rect r = new Rect(0, 0, view.getWidth(), view.getHeight());
           if (!r.contains((int)event.getX(), (int)event.getY()))
               // your action
           return true;
       }

       return false;
   }
});
