onTouchEvent is getting executed when page is swiped using ViewPager and PassByValue

Question

In my project have used onTouchEvent for detecting touch on the screen and doing action accordingly , and have used viewPager for swipe action. Problem is on swipe the touch actions are getting executed. so find the solution from here solved it. But my new Problem to it is the touch is getting disabled after once TouchEvent.Action_up gets executed. code is as follows:

parent.setOnTouchListener(new OnTouchListener() {

    public boolean onTouch(View v, MotionEvent event) {

        switch(event.getAction())
        {
         case MotionEvent.ACTION_MOVE: 
                awesomePager.requestDisallowInterceptTouchEvent(true);
                break;
        case MotionEvent.ACTION_UP:
            awesomePager.requestDisallowInterceptTouchEvent(true);
             if(flag)
             {
               upperdock.setClickable(false);
                upperdock.bringToFront();
                tocparent.bringToFront();
                tocbottom.bringToFront();
                upperdock.setVisibility(RelativeLayout.VISIBLE);
                tocparent.setVisibility(LinearLayout.VISIBLE);
                tocbottom.setVisibility(LinearLayout.VISIBLE);
                flag=false;
             }
             else
             {

                parent.bringToFront();
                upperdock.setVisibility(RelativeLayout.INVISIBLE);
                tocparent.setVisibility(LinearLayout.INVISIBLE);
                tocbottom.setVisibility(LinearLayout.INVISIBLE);
                flag=true;
             }
             break;

        case MotionEvent.ACTION_CANCEL:
            awesomePager.requestDisallowInterceptTouchEvent(false);
             break;
        default:
            break;
        }

        return false;
    }
});

In the above code if i return false Action_up is not getting executed.. if i return true Action_cancel is not getting executed..that is pass by value is the problem in there.

Answer 1

i change something for this.

not use awesomePager.requestDisallowInterceptTouchEvent(false), just use return true.

in the activity define a boolean sroll ;

set sroll = positionOffset != 0.0 in ViewPager.onPageScrolled and i override onTouchEvent in which the view in the ViewPager.

now you can check if (event.getAction()==MotionEvent.ACTION_UP && !sroll) to decide the event whether will triggered

Answer 2

I had the same problem! For me this worked very well....

case MotionEvent.ACTION_MOVE: {
        getParent().requestDisallowInterceptTouchEvent(false);
        break;
    }

 case MotionEvent.ACTION_CANCEL:{
        getParent().requestDisallowInterceptTouchEvent(true);
        break;

}

case MotionEvent.ACTION_UP:{

 //delete  awesomePager.requestDisallowInterceptTouchEvent(true);
 //you don't need it here!
                 .
                 .
            do your stuff....
                 .

}

return your whole onTouch methode as true and not false...

return true;
