我想让我的按钮在recyclerView中切换意味着当单击另一个按钮时，所有的按钮都应该是dssleted的

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<Button> buttonList;
    private int selectedPosition = -1;

    public MyAdapter(List<Button> buttonList) {
        this.buttonList = buttonList;
    }

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

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        Button button = buttonList.get(position);
        holder.button.setText(button.getText());

        // 设置按钮的状态
        if (position == selectedPosition) {
            holder.button.setSelected(true); // 设置为选中状态
        } else {
            holder.button.setSelected(false); // 设置为未选中状态
        }

        // 设置按钮的点击事件监听器
        holder.button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // 更新选中按钮的位置
                selectedPosition = position;
                notifyDataSetChanged(); // 刷新RecyclerView的显示
            }
        });
    }

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

    public static class ViewHolder extends RecyclerView.ViewHolder {
        Button button;

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