如何在同一个recyclerview的适配器类中更新recyclerview？

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<String> mData;

    public MyAdapter(List<String> data) {
        mData = data;
    }

    public void updateData(List<String> newData) {
        mData = newData;
        notifyDataSetChanged();
    }

    // 其他适配器相关的方法...

    public static class ViewHolder extends RecyclerView.ViewHolder {
        // ViewHolder相关的代码...
    }
}

// 在RecyclerView的Activity或Fragment中使用适配器
public class MyActivity extends AppCompatActivity {
    private RecyclerView mRecyclerView;
    private MyAdapter mAdapter;

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

        mRecyclerView = findViewById(R.id.recycler_view);

        // 初始化RecyclerView的LayoutManager和数据集
        LinearLayoutManager layoutManager = new LinearLayoutManager(this);
        mRecyclerView.setLayoutManager(layoutManager);
        List<String> data = new ArrayList<>();
        mAdapter = new MyAdapter(data);

        // 设置RecyclerView的适配器
        mRecyclerView.setAdapter(mAdapter);
    }

    // 当需要更新RecyclerView时调用该方法
    private void updateRecyclerView() {
        List<String> newData = new ArrayList<>();
        // 添加新的数据到newData中...

        mAdapter.updateData(newData);
    }
}
