通讯录中的联系人操作  
(有兴趣可以查看com.android.providers.contacts.ContactsProvider2类和android.provider.ContactsContract类)  
通过ContentProvider操作通讯录，对联系人信息进行添加、删除、修改、查询操作  
在AndroidManifest.xml添加读写联系人信息的权限  
<uses-permission android:name="android.permission.READ\_CONTACTS" />  
<uses-permission android:name="android.permission.WRITE\_CONTACTS" />  
需要使用到的相关Uri:  
content://com.android.contacts/contacts 操作的数据是联系人信息  
content://com.android.contacts/data/phones 操作的数据是联系人电话  
content://com.android.contacts/data/emails 操作的数据是联系人Email  
与通讯录相关的数据库表

\\data\\data\\com.android.providers.contacts\\databases\\contact2.db

raw\_contacts表、data表

1、获取联系人
