Android编程基于Contacts读取联系人的方法(附demo源码)

本文实例讲述了Android编程基于Contacts读取联系人的方法。分享给大家供大家参考，具体如下：

Android Contacts简介：

这里介绍安卓通讯录数据库。包括Android使用Contacts访问SQLite的基本知识，并了解Android SQLite和Contacts的更多信息。谷歌改变了从版本1到版本2的Contacts数据库。下面加以简单介绍。

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<HashMap<String, String>> 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<HashMap<String, String>> getPeopleInPhone2(){ 

									  ArrayList<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>(); 

									  Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);  // 获取手机联系人 

									  while (cursor.moveToNext()) { 

									   HashMap<String, String> map = new HashMap<String, String>(); 

									   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; 

									 } 

									}
