获取recyclerView中选定内容的id

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<DataItem> dataItems;
    private OnItemClickListener listener;

    public MyAdapter(List<DataItem> dataItems, OnItemClickListener listener) {
        this.dataItems = dataItems;
        this.listener = listener;
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        // 创建ViewHolder
        // ...
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        // 绑定数据到ViewHolder
        // ...
        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // 触发点击事件回调
                listener.onItemClick(position);
            }

    }

    @Override
