看到某些App里面有读取联系人的功能，然后自己尝试了一下。发现这个挺简单的。然后自己就做了一个demo给大家，希望借这个demo可以让大家学习一下怎么实现读取手机联系人。
这里我用了两种方法去读取：第一张图片是跳转到系统自带的联系人界面，第二种就是直接去读取让后绑上来显示在主页面。话不多说直接上代码。
记得在AndroidManifest.xml 记得加入这两句，不然就读取不到联系人。
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
