Android获取手机联系人信息

Android如何获取手机联系人信息，本文为大家揭晓。

获取手机联系人信息步骤：

1、获取 ContentResolver

ContentResolver resolver = getContentResolver();

2、resolver.query(*)查询信息

查询手机联系人的URI：ContactsContract.RawContacts.CONTENT_URI
查询手机联系人手机号的URI：ContactsContract.CommonDataKinds.Phone.CONTENT_URI
查询联系人邮箱的URI：ContactsContract.CommonDataKinds.Email.CONTENT_URI

3、根据联系人名字的_id查询对应的手机号和邮箱

在手机号和邮箱查询中找到raw_contact_id与联系人的_id相等的条目

主要代码如下：

MainActivity.java

package com.noonecode.contentresolvercontacts;

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

import android.app.Activity;
import android.content.ContentResolver;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.ContactsContract.CommonDataKinds.Email;
import android.provider.ContactsContract.CommonDataKinds.Phone;
import android.provider.ContactsContract.RawContacts;
import android.widget.ListView;
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);
 }

 /**
 * 加载数据
 *
 * @return
 */
 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);

  // 联系人号码
  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);
  }

  // 联系人邮箱
  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;
 }
}

</RelativeLayout>

读取联系人的权限：

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

注意：

注意检查是否赋予了应用读取联系人的权限；
本例在主线程中读取联系人信息，效率不高，如有效率要求，请自行寻找其他方法。
