首先给大家展示下运行效果图：
由于通讯录在手机里是以数据库贮存的 所以我们可以通过一个方法
|
1
2
|
context.getcontentresolver().query(phone.content_uri,null, null, null, null); |
来获得通讯录 ,这个方法返回一个游标的数据类型，通过movetonext()方法来获取所有的手机号码信息
当然读取手机通讯录需要权限 在adnroidmanifest文件中声明即可
由于我也实现了打电话的功能 所以也要声明权限

<uses-permission android:name="android.permission.read_contacts"><uses-permission android:name="android.permission.call_phone"></uses-permission></uses-permission> |

listview的布局文件：item.xml，在这里我设置的头像为默认的 当然也可以在手机数据库中读取联系人的icon
