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. * */ import android.os.Bundle;
