android調用系統電話薄，實現增刪改查。

因為有個需求，需要調用系統電話薄，實現增刪改查後並即時重新整理頁面，寫了個demo供大家參考，取連絡人名字跟手機號碼展示在Listview上，單擊出現連絡人的詳細情況，長按出現操作功能表，彈出編輯刪除菜單，下面請看代碼。

首先在Androidmainifest中添加對電話薄的讀寫權限。

<uses-permission android:name="android.permission.READ_CONTACTS" />  <uses-permission android:name="android.permission.WRITE_CONTACTS" />

因為繼承於ListActivity，沒有用到設定檔，下面貼出java代碼。
