ContentProvider往通讯录添加联系人和获取联系人

public class MainActivity extends Activity {
private People people;
private List<People> pList;

private ListView lv_people;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

initWidgets();
Cursor cursor=getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);

while(cursor.moveToNext()){
people=new People();
people.setName(cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)));
people.setTel_num(cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
pList.add(people);
}
lv_people.setAdapter(new ArrayAdapter<People>(this, android.R.layout.simple_list_item_1,pList));

}

在Android中，可以使用ContentResolver对通信录中的数据进行添加、删除、修改和查询操作。

在对联系人进行操作时需加入以下两个权限

<!-- 添加操作联系人的权限 -->
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
<!-- 联系人相关的uri -->
content://com.android.contacts/contacts 操作的数据是联系人信息Uri
content://com.android.contacts/data/phones 联系人电话Uri
content://com.android.contacts/data/emails 联系人Email Uri

一、清单文件
