本文实例讲述了android基于api的tabs3实现仿优酷tabhost效果。分享给大家供大家参考，具体如下：
前两天老师就让自己写个视频播放器客户端，这个是他上课讲的一个小小demo,通过查看安卓api的tabs3，实现仿优酷视频客户端的tabhost效果。我的api路径是d:\android\sdk\samples\android-17\apidemos\src\com\example\android\apis\view下的tabs3，下面是实现效果：
废话不多说了，直接上码：

<!-- 配置activity组件 --><activity android:name="com.example.video.myindexactivity"/><activity android:name="com.example.video.myselfactivity"/><activity android:name="com.example.video.mycenteractivity"/> |
希望本文所述对大家android程序设计有所帮助。
