requestDisallowInterceptTouchEvent does not work unless selecting view first

Question

According to android docs you can get your parent ViewGroup and call requestDisallowInterceptTouchEvent(true) on it to stop other things from interferi

Answer 1

You can try this one:

m_parentScrollView.setOnTouchListener(new View.OnTouchListener() 
{
       public boolean onTouch(View p_v, MotionEvent p_event) 
        {
               m_childScrollView.getParent().requestDisallowInterceptTouchEvent(false);
           //  We will have to follow above for all scrollable contents
           return false;
        }
});

                                        **OR**

m_childScrollView.setOnTouchListener(new View.OnTouchListener() 
{
      public boolean onTouch(View p_v, MotionEvent p_event)
       {
          // this will disallow the touch request for parent scroll on touch of child view
           p_v.getParent().requestDisallowInterceptTouchEvent(true);
           return false;
       }
});
