需要将recyclerview点击的项目id传递给第二个recyclerview

public class FirstRecyclerViewAdapter extends RecyclerView.Adapter<FirstRecyclerViewAdapter.ViewHolder> {
    private List<Item> itemList;
    private OnItemClickListener listener;

    public interface OnItemClickListener {
        void onItemClick(int itemId);
    }

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

    // ...其他方法

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        Item item = itemList.get(position);
        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                listener.onItemClick(item.getId());
            }
        });
    }

    // ...其他方法

    public static class ViewHolder extends RecyclerView.ViewHolder {
        // ...其他视图组件

        public ViewHolder(View itemView) {
            super(itemView);
            // 初始化视图组件
        }
    }
}

public class MainActivity extends AppCompatActivity implements FirstRecyclerViewAdapter.OnItemClickListener {
    private List<Item> firstItemList;
    private List<Item> secondItemList;
    private FirstRecyclerViewAdapter firstAdapter;
    private SecondRecyclerViewAdapter secondAdapter;

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

        // 初始化第一个RecyclerView和适配器
        RecyclerView firstRecyclerView = findViewById(R.id.firstRecyclerView);
        firstItemList = generateFirstItemList(); // 生成第一个RecyclerView的数据源
        firstAdapter = new FirstRecyclerViewAdapter(firstItemList, this);
        firstRecyclerView.setAdapter(firstAdapter);

        // 初始化第二个RecyclerView和适配器
        RecyclerView secondRecyclerView = findViewById(R.id.secondRecyclerView);
        secondItemList = new ArrayList<>(); // 初始化第二个RecyclerView的数据源
        secondAdapter = new SecondRecyclerViewAdapter(secondItemList);
        secondRecyclerView.setAdapter(secondAdapter);
    }

    // 第一个RecyclerView的点击事件回调方法
    @Override
    public void onItemClick(int itemId) {
        // 根据itemId更新第二个RecyclerView的数据源
        secondItemList.clear();
        secondItemList.addAll(getSecondItemList(itemId));
        secondAdapter.notifyDataSetChanged();
    }

    // ...其他方法
}
