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;
 }
}

主布局activity_main.xml

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 tools:context="com.noonecode.contentresolvercontacts.mainactivity" >

 <listview
 android:id="@+id/lv_show"
 android:layout_width="match_parent"
 android:layout_height="match_parent" />

</relativelayout>

simple_contacts_item.xml

<?xml version="1.0" encoding="utf-8"?>
<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:padding="10dp" >

 <textview
 android:id="@+id/tv_name"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:text="name"
 android:textsize="22sp" />

 <textview
 android:id="@+id/tv_number"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_below="@id/tv_name"
 android:text="number" />

 <textview
 android:id="@+id/tv_email"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_below="@id/tv_name"
 android:layout_marginleft="10dp"
 android:layout_torightof="@id/tv_number"
 android:text="email" />

</relativelayout>

读取联系人的权限：

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