场景：

editText = (P14_ChatEditText)findViewById(R.id.p04_message_chat_send_msg);

editText.setOnTouchListener(editTextTouchListener);

OnTouchListener editTextTouchListener = new OnTouchListener(){
        @Override
        public boolean onTouch(View arg0, MotionEvent event) {

        if(event.getAction() == MotionEvent.ACTION_DOWN && dRight!=null) {
                
                rBounds = dRight.getBounds();
                final int x = (int)event.getX();
                final int y = (int)event.getY();

       //check to make sure the touch event was within the bounds of the drawable
                if(x>=(editText.getRight()-rBounds.width()) && x<=(editText.getRight()-editText.getPaddingRight())
                        && y>=editText.getPaddingTop() && y<=(editText.getHeight()-editText.getPaddingBottom()))
                {

                 }

         }

    }
