Android ContentResolver ContactsContract 獲取手機聯絡人資訊
阿新 • • 發佈:2019-02-01
獲取手機聯絡人資訊步驟:
1、獲取 ContentResolver
ContentResolver resolver = getContentResolver();
2、resolver.query(*)查詢資訊
查詢手機聯絡人的URI:ContactsContract.RawContacts.CONTENT_URI
查詢手機聯絡人手機號的URI:ContactsContract.CommonDataKinds.Phone.CONTENT_URI
查詢聯絡人郵箱的URI:ContactsContract.CommonDataKinds.Email.CONTENT_URI
3、根據聯絡人名字的_id查詢對應的手機號和郵箱
在手機號和郵箱查詢中找到raw_contact_id與聯絡人的_id相等的條目
主要程式碼如下:

import java.util.HashMap;
import java.util.List;
import java.util.Map;

import android.widget.SimpleAdapter;
public class MainActivity extends Activity {
private ListView mLvShow;
private List<Map<String, String>> dataList;
private SimpleAdapter adapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mLvShow = (ListView) findViewById(R.id.lv_show);
dataList = getDataList();
adapter = new SimpleAdapter(this, dataList, R.layout.simple_contacts_item//
, new String[] { "name", "number", "email" }//
, new int[] { R.id.tv_name, R.id.tv_number, R.id.tv_email });
mLvShow.setAdapter(adapter);
}
/**

private List<Map<String, String>> getDataList() {
List<Map<String, String>> list = new ArrayList<Map<String, String>>();
ContentResolver resolver = getContentResolver();
Cursor cursor = resolver.query(RawContacts.CONTENT_URI,
new String[] { RawContacts._ID, RawContacts.DISPLAY_NAME_PRIMARY }//
, null, null, null);
while (cursor.moveToNext()) {
Map<String, String> map = new HashMap<String, String>();
String id = cursor.getString(cursor.getColumnIndex(RawContacts._ID));// "_id"
String name = cursor.getString(cursor.getColumnIndex(RawContacts.DISPLAY_NAME_PRIMARY));// "display_name"
map.put("name", name);
// 聯絡人號碼
Cursor phoneCursor = resolver.query(Phone.CONTENT_URI//
, new String[] { Phone.NUMBER }// "data1"
, "raw_contact_id=?", new String[] { id }, null);
if (phoneCursor.moveToNext()) {
String number = phoneCursor.getString(phoneCursor.getColumnIndex(Phone.NUMBER));
map.put("number", number);
}
// 聯絡人郵箱
Cursor emailCursor = resolver.query(Email.CONTENT_URI//
, new String[] { Email.ADDRESS}// "data1"
, "raw_contact_id=?", new String[] { id }, null);
if (emailCursor.moveToNext()) {
String email = emailCursor.getString(emailCursor.getColumnIndex(Email.ADDRESS));
map.put("email", email);
}
list.add(map);
}
return list;
}
}
