如何在AlertDialog中自定义视图单选？

// 创建自定义布局文件
View customView = LayoutInflater.from(context).inflate(R.layout.custom_dialog_layout, null);

// 实例化AlertDialog.Builder
AlertDialog.Builder builder = new AlertDialog.Builder(context);

// 设置自定义视图
builder.setView(customView);

// 设置单选功能
RadioGroup radioGroup = customView.findViewById(R.id.radio_group);
radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(RadioGroup group, int checkedId) {
        // 处理单选按钮的选择事件
    }
});
builder.setSingleChoiceItems(new CharSequence[]{"选项1", "选项2", "选项3"}, -1, null);

// 设置确定按钮和取消按钮
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // 处理确定按钮的点击事件
    }
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // 处理取消按钮的点击事件
    }
});

// 创建AlertDialog
AlertDialog alertDialog = builder.create();

// 显示AlertDialog
alertDialog.show();
