如何在RecyclerView中实现单选？

// 数据模型类
public class ItemModel {
    private String name;
    private boolean isSelected;

    public ItemModel(String name) {
        this.name = name;
        this.isSelected = false;
    }

    public String getName() {
        return name;
    }

    public boolean isSelected() {
        return isSelected;
    }

    public void setSelected(boolean selected) {
        isSelected = selected;
    }
}

// 自定义适配器类
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<ItemModel> itemList;
    private OnItemSelectedListener listener;

    public MyAdapter(List<ItemModel> itemList, OnItemSelectedListener listener) {
        this.itemList = itemList;
        this.listener = listener;
    }

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

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        ItemModel item = itemList.get(position);
        holder.nameTextView.setText(item.getName());
        holder.itemView.setSelected(item.isSelected());
        holder.itemView.setOnClickListener(v -> {
            // 更新选中状态
            item.setSelected(true);
            // 通知适配器和其他相关组件
            listener.onItemSelected(position);
            notifyDataSetChanged();
        });
    }

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

    public static class ViewHolder extends RecyclerView.ViewHolder {
        TextView nameTextView;

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

    public interface OnItemSelectedListener {
        void onItemSelected(int position);
    }
}

// 在Activity或Fragment中使用
public class MainActivity extends AppCompatActivity implements MyAdapter.OnItemSelectedListener {
    private RecyclerView recyclerView;
    private MyAdapter adapter;
    private List<ItemModel> itemList;

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

        // 初始化数据
        itemList = new ArrayList<>();
        itemList.add(new ItemModel("Item 1"));
        itemList.add(new ItemModel("Item 2"));
        itemList.add(new ItemModel("Item 3"));

        // 初始化RecyclerView和适配器
        recyclerView = findViewById(R.id.recyclerView);
        adapter = new MyAdapter(itemList, this);
        recyclerView.setLayoutManager(new LinearLayoutManager(this));
        recyclerView.setAdapter(adapter);
    }

    @Override
    public void onItemSelected(int position) {
        // 处理单选事件
        for (int i = 0; i < itemList.size(); i++) {
            if (i != position) {
                itemList.get(i).setSelected(false);
            }
        }
    }
}
