如何在屏幕旋转时保持recyclerView的滚动位置

public class MyActivity extends AppCompatActivity {
    private RecyclerView recyclerView;
    private RecyclerView.LayoutManager layoutManager;
    private RecyclerView.Adapter adapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        recyclerView = findViewById(R.id.recyclerView);

        // 设置布局管理器
        layoutManager = new LinearLayoutManager(this);
        recyclerView.setLayoutManager(layoutManager);

        // 设置适配器
        adapter = new MyAdapter(data);
        recyclerView.setAdapter(adapter);

        // 恢复RecyclerView的滚动位置
        if (savedInstanceState != null) {
            Parcelable state = savedInstanceState.getParcelable("recycler_state");
            recyclerView.getLayoutManager().onRestoreInstanceState(state);
        }
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        
        // 保存RecyclerView的滚动位置
        Parcelable state = recyclerView.getLayoutManager().onSaveInstanceState();
        outState.putParcelable("recycler_state", state);
    }
}
