我正在创建一个RecyclerView它会在用户触摸它时自行展开并在用户再次触摸它时自行关闭。下面是我的代码：

public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.RecViewHolder> {

            });

        }

        public void expandLayout() {
            favResultsLayout.setVisibility(View.VISIBLE);
            resultsOpened = true;
