首先给大家展示下运行效果图：

Android实现通讯录效果——获取手机号码和姓名

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

?

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>

布局文件

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent">
<listview android:id="@+id/listview1" android:layout_width="match_parent" android:layout_height="wrap_content">
</listview>
</relativelayout>

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
