Android Ontouchlistener Stops Receiving Events When Finger Is Moved Up

I have a custom view with the following OnTouchListener assigned to it in my activity: private OnTouchListener MyOnTouchListener = new OnTouchListener() { public boolean onTouc

Solution 1:

Well this might be old, but it still comes up in the search results. It's possible to prevent the ScrollView from intercepting the touch events by doing this:

private OnTouchListener MyOnTouchListener = new OnTouchListener() {
    public boolean onTouch(View v, MotionEvent event) {
        if(event.getAction()==MotionEvent.ACTION_DOWN){
//our touch handling began, request the scrollview not to interact
scrollView.requestDisallowInterceptTouchEvent(true);
           System.out.println("Down");          
           System.out.println("x" + event.getX() + ", y: " + event.getY());
        }elseif(event.getAction()==MotionEvent.ACTION_MOVE){
           System.out.println("Move");          
           System.out.println("x" + event.getX() + ", y: " + event.getY());
        }elseif(event.getAction()==MotionEvent.ACTION_UP){
//re-enable it after we're done (finger goes up)
scrollView.requestDisallowInterceptTouchEvent(true);
           System.out.println("up");          
           System.out.println("x" + event.getX() + ", y: " + event.getY());
        }

        returntrue;
    }
};

Solution 2:

It turns out the issue is that the view is contained in a ScrollView. Removing the ScrollView fixes the problem.

Solution 3:

you have to specify the event into the onTouch like down, move or up for that you have to do like this way.

private OnTouchListener MyOnTouchListener = new OnTouchListener() {
    public boolean onTouch(View v, MotionEvent event) {
        if(event.getAction()==MotionEvent.ACTION_DOWN){
           System.out.println("Down");          
           System.out.println("x" + event.getX() + ", y: " + event.getY());
        }elseif(event.getAction()==MotionEvent.ACTION_MOVE){
           System.out.println("Move");          
           System.out.println("x" + event.getX() + ", y: " + event.getY());
        }elseif(event.getAction()==MotionEvent.ACTION_UP){
           System.out.println("up");          
           System.out.println("x" + event.getX() + ", y: " + event.getY());
        }

        returntrue;
    }
};
