如何确定在recycelview布局上单击了哪个卡片视图？

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<Item> itemList;
    private OnItemClickListener onItemClickListener; // 内部接口

    public interface OnItemClickListener {
        void onItemClick(Item item);
    }

    public MyAdapter(List<Item> itemList, OnItemClickListener listener) {
        this.itemList = itemList;
        this.onItemClickListener = listener;
    }

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

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        Item item = itemList.get(position);
        holder.bind(item);
    }

    @Override
    public int getItemCount() {
        return itemList.size();
    }

    public class ViewHolder extends RecyclerView.ViewHolder {
        private CardView cardView;

        public ViewHolder(@NonNull View itemView) {
            super(itemView);
            cardView = itemView.findViewById(R.id.cardView);

            cardView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    int position = getAdapterPosition();
                    if (position != RecyclerView.NO_POSITION) {
                        Item item = itemList.get(position);
                        onItemClickListener.onItemClick(item);
                    }
                }
            });
        }

        public void bind(Item item) {
            // 绑定数据到卡片视图
        }
    }
}

public class MainActivity extends AppCompatActivity implements MyAdapter.OnItemClickListener {
    private RecyclerView recyclerView;
    private MyAdapter adapter;

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

        List<Item> itemList = // 获取数据列表

        recyclerView = findViewById(R.id.recyclerView);
        adapter = new MyAdapter(itemList, this);
        recyclerView.setAdapter(adapter);
        recyclerView.setLayoutManager(new LinearLayoutManager(this));
    }

    @Override
    public void onItemClick(Item item) {
        // 处理点击事件，例如获取item的相关信息
    }
}
