/**
 * AlertDialog:
 * 1、AlertDialog的功能很强大,它可以生成各种内容的对话框,实际上AlertDialog生成的
 * 的对话框总可以分为4个区域:(1)图标区(2)标题区(3)内容区(3)按钮区。
 * 2、创建一个对话框需要经过如下几个步骤:
 * (1)使用创建AlertDialog.Builder对象。
 * (2)调用AlertDialog.Builder的setTitle()或setCustomTitle()方法设置标题
 * (3)调用AlertDialog.Builder的setIcon()方法设置标题
 * (4)调用AlertDialog.Builder的相关设置方法设置对话框内容
 * (5)调用AlertDialog.Builder的setPositiveButton()、setNegativeButton()或setNeutralButton()方法添加多个按钮
 * (6)调用AlertDialog.Builder的create()方法创建AlertDialog对象,再调用AlertDialog对象的show()方法将该对话框显示出来。
 * 3、AlertDialog提供了如下6种方法来指定对话框内容:
 * (1)setMessage():设置对话内容为简单文本内容。
 * (2)setItems():设置对话框内容为简单列表项
 * (3)setSingleChoiceItems():设置对话框内容为单选列表项
 * (4)setMultiChoiceItems():设置对话框内容为多选列表项
 * (5)setAdapter():设置对话框内容为自定义列表项
 * (6)setView():设置对话框内容为自定义View.
