如何更新单个RecyclerView项目的计数器？

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<Item> itemList;

    public MyAdapter(List<Item> itemList) {
        this.itemList = itemList;
        // 初始化计数器变量的初始值
        for (int i = 0; i < itemList.size(); i++) {
            itemList.get(i).setCounter(0);
        }
    }

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

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        Item item = itemList.get(position);
        // 更新计数器视图的显示
        holder.counterTextView.setText(String.valueOf(item.getCounter()));
        // ...
    }

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

    public void updateCounter(int position, int newCounter) {
        // 更新计数器变量的值
        itemList.get(position).setCounter(newCounter);
        // 刷新对应项目的视图
        notifyItemChanged(position);
    }

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

        public ViewHolder(@NonNull View itemView) {
            super(itemView);
            // 找到计数器视图并进行绑定
            counterTextView = itemView.findViewById(R.id.counterTextView);
        }
    }
}

public class Item {
    private int counter;

    public int getCounter() {
        return counter;
    }

    public void setCounter(int counter) {
        this.counter = counter;
    }
}
