Answer 1

All you need is to call

requestDisallowInterceptTouchEvent(true);

on the parent view, like this -

        @Override
        public boolean onTouch(View view, MotionEvent motionEvent) {
            view.getParent().requestDisallowInterceptTouchEvent(true);
            switch(motionEvent.getActio){
            }

            return false; 

         }
