如何在RecyclerView中使用android中的适配器类给出序列号？

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<DataModel> mDataList;

    // 构造函数传入数据列表
    public MyAdapter(List<DataModel> dataList) {
        mDataList = dataList;
    }

    // 创建ViewHolder
    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_layout, parent, false);
        return new ViewHolder(view);
    }

    // 绑定ViewHolder
    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        DataModel data = mDataList.get(position);
        holder.bindData(data, position);
    }

    // 返回数据项数量
    @Override
    public int getItemCount() {
        return mDataList.size();
    }

    // ViewHolder定义
    public static class ViewHolder extends RecyclerView.ViewHolder {
        private TextView mSerialNumberTextView;
        private TextView mDataTextView;

        public ViewHolder(View itemView) {
            super(itemView);
            mSerialNumberTextView = itemView.findViewById(R.id.serial_number_text_view);
            mDataTextView = itemView.findViewById(R.id.data_text_view);
        }

        public void bindData(DataModel data, int position) {
            // 设置序列号
            mSerialNumberTextView.setText(String.valueOf(position + 1));
            // 设置数据
            mDataTextView.setText(data.getData());
        }
    }
}

<!-- item_layout.xml -->
<LinearLayout
    ...
    >

    <TextView
        android:id="@+id/serial_number_text_view"
        ... />

    <TextView
        android:id="@+id/data_text_view"
        ... />

</LinearLayout>

public class MainActivity extends AppCompatActivity {
    private RecyclerView mRecyclerView;
    private MyAdapter mAdapter;

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

        // 初始化RecyclerView
        mRecyclerView = findViewById(R.id.recycler_view);
        mRecyclerView.setLayoutManager(new LinearLayoutManager(this));

        // 创建数据列表
        List<DataModel> dataList = new ArrayList<>();
        dataList.add(new DataModel("Data 1"));
        dataList.add(new DataModel("Data 2"));
        // ...

        // 创建适配器并设置给RecyclerView
        mAdapter = new MyAdapter(dataList);
        mRecyclerView.setAdapter(mAdapter);
    }
}
