Java Android AlertDialog，带有3个按钮的公共消息

请帮我写代码 我需要显示一个Android

AlertDialogBox

，其中包含3个按钮的常见消息，即是、否和取消。在这里，我使用了简单的Android AlertDialog，其中包含一条消息，用于单独的3个按钮，即Yes、No和Cancel。 所以我认为需要调用函数

下面给出了布局和Java部分

布局

 <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout

分配

AlertDialog

对象并将其分配给

builder.create（）

不，它不起作用。当我使用alertDialog.show（）单击这三个按钮时，我只需要得到一个“警报”；
