Android从SIM卡中获取联系人信息
来源：互联网 发布：家用跑步机推荐 知乎 编辑：程序博客网 时间：2024/05/22 08:21
Uri uri = Uri.parse("content://icc/adn"); String[] projection = {"_id", "name", "number"}; Cursor cursor = managedQuery(uri, projection, null, null, "name"); if(cursor!=null){ while(cursor.moveToNext()){ String name = cursor.getString(cursor.getColumnIndex("name")); String phone = cursor.getString(cursor.getColumnIndex("number")); } } 在文件AndroidManifest.xml中添加权限
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
Android系统内部通过Contentprovider对外共享Sim卡存放的联系人等信息，你可以通过操作Contentprovider来实现Sim卡信息的添删改查操作。 内部实现源代码见下：
