Try this:

  contenuRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
        @Override
        public void onScrolled(@NonNull RecyclerView recyclerView, int dx, int dy) {
            super.onScrolled(recyclerView, dx, dy);

            if (yourLayoutManager.findFirstVisibleItemPosition() != 1){
                // visible toolbar
            } else {
                // gone toolbar
            }

        }
    });
