获取手机通讯录

来源：互联网发布：sql简单查询语句编辑：程序博客网时间：2024/05/17 22:49

首先是运行结果

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>

布局文件

activity_main.xml

<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
