Touch Release method in Android

Question

I'm trying to capture the TouchRelease event in Android. I have seen that event.getAction() returns the action type. But inside onTouchEvent it always gives the action ACTION_DOWN.
Do you know how to capture the touch release event.

public boolean onTouchEvent(MotionEvent event) {
  Log.d(TAG,""+event.getAction());
  return super.onTouchEvent(event);
}

You can use ACTION_UP: http://developer.android.com/reference/android/view/MotionEvent.html#ACTION_UP

View view = new View();

view.setOnTouchListener(new OnTouchListener () {
  public boolean onTouch(View view, MotionEvent event) {
    if (event.getAction() == android.view.MotionEvent.ACTION_DOWN) {
      Log.d("TouchTest", "Touch down");
    } else if (event.getAction() == android.view.MotionEvent.ACTION_UP) {
      Log.d("TouchTest", "Touch up");
    }
    return true;
  }
});

Consider evaluating also `ACTION_CANCEL` – Aleadam Apr 23 '11 at 18:03
i saw that there is some thing called ACTION_UP. But from the above given method it never triggers with ACTION_UP state. Do you know any other method to get that? – dinesh707 Apr 23 '11 at 18:04

`ACTION_UP` is the right `MotionEvent`. Maybe the event is consumed by some other view? – Aleadam Apr 23 '11 at 18:24

@dinesh707 In your `onTouchEvent` overridden method, simply return `true` instead of `super.onTouchEvent` and then you will get the rest of the events. – Jashaszun Oct 10 '13 at 13:24

@Aleadam: I think a return statement ist missing... ;) – Willi Mentzel Jun 19 '16 at 16:44

public boolean onTouchEvent(MotionEvent event) {
        Log.d(TAG,""+event.getAction());
        return true; // Required for recieving subsequent events (ACTION_MOVE, ACTION_UP)
}

            // release

I had the same problem with class SurfaceView. Here's how I fixed it: After enabling your view's long clickable property(through setLongClickable(true)), it should works.
