Android通讯录管理（获取联系人、通话记录、短信消息）（二）

Android通讯录管理（获取联系人、通话记录、短信消息）（二）

前言：上一篇博客介绍的是获取联系人的实现，本篇博客将介绍通话记录的实现。

同样的，你可以到这里下载源码：http://download.csdn.net/detail/wwj_748/6962865

界面布局：

定义实体类：

/Contact_Demo/src/com/suntek/contact/model/CallLogBean.java

package com.suntek.contact.model;

/**

public class CallLogBean {

	private int id;
	private String name; // 名称
	private String number; // 号码
	private String date; // 日期
	private int type; // 来电:1，拨出:2,未接:3
	private int count; // 通话次数

	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {

	public String getDate() {

代码是最好的解释了，这里使用的几个重要的类，一个是Uri（进行查询的通用资源标志符），一个是AsyncQueryHandler（Android提供的异步操作数据库的类），这里我们调用它的startQuery方法来查询数据库，在它onQueryComplete方法中得到数据库返回的游标cousor，通过curor来取得数据库对应表中的字段值。
