轉：一個Demo學完Android中全部的服務

這個例子來自「安卓巴士」，經閱讀，理解，寫此文章，但願經過這篇一個Demo學完Android中全部的服務對對廣大讀者有所幫助。

說明：這個例子實現了Android中常見的許多服務，下面是實現的截圖

接下來，以源代碼的方式分析這個例子

1.MainActivity--主界面

這個類主要是實現用戶所看到的這個Activity，其中包含了一系列的按鈕，用戶點擊按鈕執行相應的動做，因此在這個類中主要是對按鈕的定義和對按鈕綁定相應的監聽器，下面是實現的代碼：

    Button shutDownServiceButton;// 關閉服務按鈕       
    Button startBindServiceButton;// 啓動綁定服務按鈕       
    Button sendBroadcast;// 使用廣播       
    Button notificationButton;// 使用通知功能       
    Button alarmButton;// 使用鬧鐘       
    Button handlerButton;// 使用handler       
    Button asyncButton;// 使用異步加載       
    Button phoneStateButton;// 查看手機狀態
