先了解一下AlertDialog.Builder创建对话框的几个常用方法：

setTitle() ：设置标题
setIcon() ：设置图标
setMessage()：设置提示内容
setView() ： 设置自定义视图
setItems() ：设置对话框要显示的一个list
setMultiChoiceItems() ：设置对话框显示的复选框
setNeutralButton() ：普通按钮

setPositiveButton() ：添加"Yes"按钮
setNegativeButton() ：添加"No"按钮
create() ： 创建对话框

show() ：显示对话框

下面以一个例子简单演示一下其应用，先看一下效果图：

代码示例如下：

一个主activity，两个布局文件；
