本文介绍了如何在Android中通过ContentResolver访问联系人等数据。首先需要在应用清单文件中添加权限声明，然后使用getContentResolver()方法获取ContentResolver实例，并通过query()方法查询数据。文中还提供了查询短信等其他数据的方法概述。

We all know android has content provider, and we can access these data with content resolver,

1) add permission,

        <uses-permission android:name="android.permission.READ_CONTACTS" />

2) getContentResolver

        ContentResolver cr = getContentResolver();
        Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,

3) Enumerate and Query



For other data, for example, sms,etc,  it‘s similar, the only different is the uri, have fun!
