Answer 1

did you try to hide it programatically ?

recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
        @Override
        public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
            super.onScrolled(recyclerView, dx, dy);
            my_relative_layout.setVisibility(View.GONE);
        }
    });
