Resolved my problem with bellow code :

    viewHolder.rcyNested.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            v.getParent().requestDisallowInterceptTouchEvent(true);
            return false;
        }
    });
