Android之使用ContentResolver对通信录中的数据进行简单操作

1.加入读写权限

Xhtml代码

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

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

联系人信息Uri：

content://com.android.contacts/contacts

联系人电话Uri：

content://com.android.contacts/data/phones

联系人Email Uri：

content://com.android.contacts/data/emails

（推荐）也可以这样获取联系人信息Uri：Uri uri = ContactsContract.Contacts.CONTENT_URI;

2.查询与添加联系人的操作（单元测试用例）

Java代码

1. public class ContactTest extends AndroidTestCase
2. {
3. private static final String TAG = "ContactTest";
4. 
   
5. /**
6. * 获取通讯录中所有联系人的简单信息
7. * @throws Throwable
8. */
9. public void testGetAllContact() throws Throwable
10. {
11. //获取联系人信息的Uri
12. Uri uri = ContactsContract.Contacts.CONTENT_URI;
13. //获取ContentResolver
14. ContentResolver contentResolver = this.getContext().getContentResolver();
15. //查询数据，返回Cursor
16. Cursor cursor = contentResolver.query(uri, null, null, null, null);
17. while(cursor.moveToNext())
18. {
19. StringBuilder sb = new StringBuilder();
20. //获取联系人的ID
21. String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
22. //获取联系人的姓名
23. String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
24. //构造联系人信息
25. sb.append("contactId=").append(contactId).append(",Name=").append(name);
26. //查询电话类型的数据操作
27. Cursor phones = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
28. null,
29. ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,
30. null, null);
31. while(phones.moveToNext())
32. {
33. String phoneNumber = phones.getString(phones.getColumnIndex(
34. ContactsContract.CommonDataKinds.Phone.NUMBER));
35. //添加Phone的信息
36. sb.append(",Phone=").append(phoneNumber);
37. }
38. phones.close();
39. 
    
40. //查询Email类型的数据操作
41. Cursor emails = contentResolver.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,
42. null,
43. ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId,
44. null, null);
45. while (emails.moveToNext())
46. {
47. String emailAddress = emails.getString(emails.getColumnIndex(
48. ContactsContract.CommonDataKinds.Email.DATA));
49. //添加Email的信息
50. sb.append(",Email=").append(emailAddress);
51. }
52. emails.close();
53. Log.i(TAG, sb.toString());
54. }
55. cursor.close();
56. }
57. 
    
58. /**添加联系人的第一种方法：
