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。

AndroidManifest.xml 权限
记得在AndroidManifest.xml中加入android.permission.READ_CONTACTS这个permission
复制代码 代码如下:
<uses-permission android:name="android.permission.READ_CONTACTS" />
运行结果:
