OnTouch.kt

editTextNumber.setOnTouchListener(object : View.OnTouchListener{//editTextNumber is the id of my EditText that contains the drawable
        @SuppressLint("ClickableViewAccessibility")
        override fun onTouch(view: View?, event: MotionEvent?): Boolean {
            if (event?.action == MotionEvent.ACTION_UP){
                if (event.rawX >= editTextNumber.right - editTextNumber.compoundDrawables[2].bounds.width()){ //*Why [2]? See below
                    Log.d("DrawableEnd", "Pressed")//Insert your action here
                    return true
                }
            }
            return false
        }
    })  
/* DRAWABLE_LEFT = 0
   DRAWABLE_TOP = 1
   DRAWABLE_RIGHT = 2
   DRAWABLE_BOTTOM = 3*/
