    final int action = event.getAction(); 

     if(view.getId()==R.id.yourButton){ 
      if(action == MotionEvent.ACTION_DOWN) 
        yourButton.setBackgroundResource(R.drawable.ic_button_green); 
      if(action == MotionEvent.ACTION_UP) 
        yourButton.setBackgroundResource(R.drawable.ic_button_red); 
     }
