Disable or prevent multitouch in Activity


I have several Views on an Activity which a user wants to touch quickly in succession and I capture these touches using a TouchListener and handling MotionEvent.ACTION_DOWN. However, if the user is using two hands, it's very likely that the next View will be 'Touch'ed before the user pulls the previous finger up. In this scenario, a MotionEvent.ACTION_MOVE is fired for the first view rather than the desired MotionEvent.ACTION_DOWN for the second view.

Is there any way to work around or prevent this behavior? I've tried dispatching a new event with MotionEvent.ACTION_UP and also removing the event listener but neither seem to work.


Solution

  • The best way to work around this scenario is to use a ViewGroup and implement the onInterceptTouchEvent method to manually route the touch events as you see fit.
