RecycleView多个按钮应该保存来自volley的用户id，并在单击按钮时将用户id发送到数据库

public class User {
    private String userId;
    // 其他用户信息字段

    public User(String userId) {
        this.userId = userId;
    }

    public String getUserId() {
        return userId;
    }

    // 其他getter和setter方法
}

public class UserAdapter extends RecyclerView.Adapter<UserAdapter.ViewHolder> {
    private List<User> userList;
    // 其他成员变量和构造函数

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        // 创建ViewHolder并绑定布局文件
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_user, parent, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        // 绑定数据到ViewHolder
        User user = userList.get(position);
        holder.bind(user);
    }

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

    public class ViewHolder extends RecyclerView.ViewHolder {
        private TextView userIdTextView;
        private Button button1;
        private Button button2;
        // 其他视图组件

        public ViewHolder(@NonNull View itemView) {
            super(itemView);
            // 初始化视图组件
            userIdTextView = itemView.findViewById(R.id.text_user_id);
            button1 = itemView.findViewById(R.id.button1);
            button2 = itemView.findViewById(R.id.button2);

            // 设置按钮点击事件
            button1.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    int position = getAdapterPosition();
                    User user = userList.get(position);
                    String userId = user.getUserId();
                    // 将用户ID发送到数据库
                    sendUserIdToDatabase(userId);
                }
            });

            // 设置其他按钮点击事件
            // ...
        }

        public void bind(User user) {
            // 绑定数据到视图组件
            userIdTextView.setText(user.getUserId());
            // 绑定其他用户信息到视图组件
            // ...
        }
    }

    private void sendUserIdToDatabase(String userId) {
        // 使用Volley发送网络请求将用户ID发送到数据库
        // ...
    }
}

<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/recycle_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

public class MainActivity extends AppCompatActivity {
    private RecyclerView recyclerView;
    private UserAdapter userAdapter;
    private List<User> userList;

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

        // 初始化RecycleView和适配器
        recyclerView = findViewById(R.id.recycle_view);
        userList = new ArrayList<>();
        // 添加用户数据到userList
        // ...
        userAdapter = new UserAdapter(userList);
