AndroidUI組件之AlertDialog

package com.gc.alertdialogdemo;
/**
 * AlertDialog：
 * 1、AlertDialog的功能很強大，它可以生成各種內容的對話框，實際上AlertDialog生成的
 * 的對話框總可以分為4個區域：（1）圖標區（2）標題區（3）內容區（3）按鈕區。
 * 2、創建一個對話框需要經過如下幾個步驟：
 * （1）使用創建AlertDialog.Builder對象。
 * （2）調用AlertDialog.Builder的setTitle()或setCustomTitle()方法設置標題
 * （3）調用AlertDialog.Builder的setIcon()方法設置標題
 * （4）調用AlertDialog.Builder的相關設置方法設置對話框內容
 * （5）調用AlertDialog.Builder的setPositiveButton()、setNegativeButton()或setNeutralButton()方法添加多個按鈕
 * （6）調用AlertDialog.Builder的create()方法創建AlertDialog對象，再調用AlertDialog對象的show()方法將該對話框顯示出來。
 * 3、AlertDialog提供了如下6種方法來指定對話框內容：
 * （1）setMessage():設置對話內容為簡單文本內容。
 * （2）setItems():設置對話框內容為簡單列表項
 * （3）setSingleChoiceItems():設置對話框內容為單選列表項
 * （4）setMultiChoiceItems():設置對話框內容為多選列表項
 * （5）setAdapter()：設置對話框內容為自定義列表項
 * （6）setView():設置對話框內容為自定義View.
