通訊錄中的聯絡人操作
(有興趣可以檢視com.android.providers.contacts.ContactsProvider2類和android.provider.ContactsContract類)
通過ContentProvider操作通訊錄，對聯絡人資訊進行新增、刪除、修改、查詢操作
在AndroidManifest.xml新增讀寫聯絡人資訊的許可權
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
需要使用到的相關Uri:
content://com.android.contacts/contacts 操作的資料是聯絡人資訊
content://com.android.contacts/data/phones 操作的資料是聯絡人電話
content://com.android.contacts/data/emails 操作的資料是聯絡人Email
與通訊錄相關的資料庫表

raw_contacts表、data表

1、獲取聯絡人
