讀取聯繫人需要獲取權限：android.permission.READ_CONTACTS
android.permission.WRITE_CONTACTS
具體例題如http://yunpan.cn/cZNcQw3cf3Spb 訪問密碼 9d90————ReadContact文件
public class ReadContactActivity extends Activity

Called when the activity is first created. */

//1，查詢raw_contact表獲取聯繫人的id
//獲取中間人
ContentResolver resolver = getContentResolver();
//獲取raw_contacts表的 uri

//查詢raw_cantact

//2。獲取data表

randTv.setText(list.toString());
