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; } }

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。
