Android通讯录管理（获取联系人、通话记录、短信消息）（一）

Android通讯录管理（获取联系人、通话记录、短信消息）
2014年2月26日通讯录开发研究学习
前言：前阵子主要是记录了如何对联系人的一些操作，比如搜索，全选、反选和删除等在实际开发中可能需要实现的功能，本篇博客是小巫从一个别人开源的一个项目抽取出来的部分内容，把它给简化出来，可以让需要的朋友清楚知道如何对Android数据库操作，异步查询数据库获取我们需要的内容。由于内容比较多，我将分三篇博客来讲述获取联系人、通话记录、短信消息的实现。

也许你根本就没耐心看，源码在这里http://download.csdn.net/detail/wwj_748/6962865，骚年去下吧。

上面的是获取联系人的界面效果，实现分组显示联系人，快速索引条查找联系人，下面是实现：
从权限开始：

界面布局： /Contact_Demo/res/layout/contact_list_view.xml

<?xml version="1.0" encoding="utf-8"?>

/Contact_Demo/res/layout/contact_list_item.xml

<?xml version="1.0" encoding="utf-8"?>

代码实现：
1. 先定义一个实体类，用来保存联系人信息 /Contact_Demo/src/com/suntek/contact/model/ContactBean.java

package com.suntek.contact.model;public class ContactBean {private int contactId; //idprivate String desplayName;//姓名private String phoneNum; // 电话号码private String sortKey; // 排序用的private Long photoId; // 图片idprivate String lookUpKey; private int selected = 0;private String formattedNumber;private String pinyin; // 姓名拼音public int getContactId() {return contactId;}public void setContactId(int contactId) {this.contactId = contactId;}public String getDesplayName() {return desplayName;}public void setDesplayName(String desplayName) {this.desplayName = desplayName;}public String getPhoneNum() {return phoneNum;}public void setPhoneNum(String phoneNum) {this.phoneNum = phoneNum;}public String getSortKey() {return sortKey;}public void setSortKey(String sortKey) {this.sortKey = sortKey;}public Long getPhotoId() {return photoId;}public void setPhotoId(Long photoId) {this.photoId = photoId;}public String getLookUpKey() {return lookUpKey;}public void setLookUpKey(String lookUpKey) {this.lookUpKey = lookUpKey;}public int getSelected() {return selected;}public void setSelected(int selected) {this.selected = selected;}public String getFormattedNumber() {return formattedNumber;}public void setFormattedNumber(String formattedNumber) {this.formattedNumber = formattedNumber;}public String getPinyin() {return pinyin;}public void setPinyin(String pinyin) {this.pinyin = pinyin;}}
