Android Contacts（一）—— 读取联系人

Introduction To Android Contacts

Learn to work with the Android contacts database. Basic knowledge of accessing SQLite in Android along with using Cursors is expected. See the Android
SQLite and Cursor Article for more information. Google changed the contacts database moving from 1.x to 2.0 versions of Android. This tutorial will be broken into 3 sections. First covering accessing contacts in Android 2.0. The second page will deal with
accessing the contacts in Android 1.6 and before. Third we'll glue it all together with a class that abstracts specific classes for each version and a set of classes to manage the data from the contact records.

Android联系人的介绍

学习使用Android联系人的数据库。假设你已经了解在Android中通过Cursor使用SQLite的基本知识，更多信息请查阅 “Android SQLite and Cursor Article” 。Google在Android升级到2.0时对联系人数据库进行了修改，该教程将分为3个章节：1.在Android
2.0中获取联系人数据；2.在Android 1.6及之前版本中获取联系人的方法；3.通过一个抽象类对各版本获取联系人数据的操作进行统一，总结一系列用来管理从通讯录中获取到的数据的类。

Contacts 读取代码：

package com.homer.phone;

import java.util.ArrayList;
import java.util.HashMap;

import android.app.Activity;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.provider.ContactsContract.CommonDataKinds.Phone;
import android.widget.ListView;
import android.widget.SimpleAdapter;

public class phoneRead extends Activity {

@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);

showListView();
}

private void showListView(){
ListView listView = new ListView(this);

ArrayList> list = getPeopleInPhone2();
SimpleAdapter adapter = new SimpleAdapter(
this,
list,
android.R.layout.simple_list_item_2,
new String[] {"peopleName", "phoneNum"},
new int[]{android.R.id.text1, android.R.id.text2}
);
listView.setAdapter(adapter);

setContentView(listView);
}

private ArrayList> getPeopleInPhone2(){
ArrayList> list = new ArrayList>();

Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);		// 获取手机联系人
while (cursor.moveToNext()) {
HashMap map = new HashMap();

int indexPeopleName = cursor.getColumnIndex(Phone.DISPLAY_NAME); 	// people name
int indexPhoneNum = cursor.getColumnIndex(Phone.NUMBER);	 		// phone number

String strPeopleName = cursor.getString(indexPeopleName);
String strPhoneNum = cursor.getString(indexPhoneNum);

map.put("peopleName", strPeopleName);
map.put("phoneNum", strPhoneNum);
list.add(map);
}
if(!cursor.isClosed()){
cursor.close();
cursor = null;
}

return list;
}
}

AndroidManifest.xml 权限

记得在AndroidManifest.xml中加入android.permission.READ_CONTACTS这个permission

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