设计一个AlertDialog的类,弹出框用setview,根据传递过来的String[],设置单选,确认后返回选择结果,请给出代码

好的，这是一个关于AlertDialog的代码示例：

public class MyAlertDialog {
    private Context context;
    private String[] items;
    private int choice = -1;

    public MyAlertDialog(Context context, String[] items) {
        this.context = context;
        this.items = items;
    }

    public int createAlertDialog() {
        AlertDialog.Builder builder = new AlertDialog.Builder(context);
        builder.setTitle("请选择你的答案:");

        builder.setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                choice = which;
            }
        });

        builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                // do something when click "OK"
            }
        });

        builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                // do something when click "Cancel"
            }
        });

        builder.setView(view);
        AlertDialog dialog = builder.create();
        dialog.show();

        return choice;
    }
}

这个类中，我们接收一个字符串数组作为选择项，并且使用setSingleChoiceItems方法将其设置为单选项。当用户点击“确定”按钮时，我们将选择结果返回。
