如何在重新创建片段时恢复以前的RecyclerView状态？

public class YourFragment extends Fragment {
    private RecyclerView recyclerView;
    private RecyclerView.LayoutManager layoutManager;
    private RecyclerView.Adapter adapter;
    private Parcelable recyclerViewState;

    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        if (recyclerView != null) {
            recyclerViewState = recyclerView.getLayoutManager().onSaveInstanceState();
            outState.putParcelable("recycler_state", recyclerViewState);
        }
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.your_fragment_layout, container, false);
        recyclerView = view.findViewById(R.id.recycler_view);
        layoutManager = new LinearLayoutManager(getActivity());
        adapter = new YourAdapter();

        recyclerView.setLayoutManager(layoutManager);
        recyclerView.setAdapter(adapter);

        if (savedInstanceState != null) {
            recyclerViewState = savedInstanceState.getParcelable("recycler_state");
        }

        return view;
    }

    @Override
    public void onResume() {
        super.onResume();
        if (recyclerViewState != null) {
            recyclerView.getLayoutManager().onRestoreInstanceState(recyclerViewState);
        }
    }
}
