when(event.action){
  MotionEvent.ACTION_DOWN -> {myhandler.post{myrunnableaction} true}
  MotionEvent.ACTION_UP -> { myhandler.removeCallbacks(myrunnableaction) true}
}
view.onTouchEvent(event) ?: true

Answer 1

removeCallbacks method removes you Runnable from message queue, when your Runnable already launched you can't remove that with removeCallbacks method because already launched.
