看了下第一期的访问量，100都没有可能很多人不需要吧，之前跟过一个大神学做项目，他都不吧核心代码告诉我，感觉没有一点分享精神，所以我就自己做。没跟他一起做

这里把上次的代码分享一下 我这里分享的跟我博客里面可能不一样因为我已经做完第一个模块了，代码就没有分开了

第一期的代码地址：http://download.csdn.net/detail/u010982856/8232855

分享的是类似的代码 基本跟我的是一样。如果需要的联系人我把 或者加入我的交流群吧

-----------欢迎加入交流群 386451316 有问题一起讨论吧

还废话一下 这期的代码需要在下一期公布地址

开始代码了  布局文件就不写了 这期说得是联系人的问题  在源代码中有相应代码  我也参考了一些 

源代码地址：sdk\sources\android-16\com\android\internal\telephony\ 里面是通讯录的所有操作

写一个bean来存放联系人信息（这就一废话是把）

package com.zw.weiyi.enety;
import android.graphics.Bitmap;
public class Person {
	private Long id;//联系人id
	public String name;//联系人名字
	public String phoneNumber;//联系人号码
	private Long iconId;//头像id
	private Bitmap icon;//头像
	private String sortLetters;  //显示数据拼音的首字母
	public String getSortLetters() {
		return sortLetters;
	}
	public void setSortLetters(String sortLetters) {
		this.sortLetters = sortLetters;
	}
	public Long getId() {
		return id;
	}
	public void setId(Long id) {
		this.id = id;
	}
	public Long getIconId() {
		return iconId;
	}
	public void setIconId(Long iconId) {
		this.iconId = iconId;
	}
	public Bitmap getIcon() {
		return icon;
	}
	public void setIcon(Bitmap icon) {
		this.icon = icon;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getPhoneNumber() {
		return phoneNumber;
	}
	public void setPhoneNumber(String phoneNumber) {
		this.phoneNumber = phoneNumber;
	}
}

这种比较好一点  但我没有用这种 我使用的内容提供者 ContentResolver 来获取  这种更新能力不好

上代码吧 只传了核心代码 我觉得有这些就够了
