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:

tabhost.addtab(tabhost.newtabspec("mycenter")

.setindicator("频道中心")

.setcontent(new intent(this, mycenteractivity.class)));

//指定的当前的tab

//通过索引指定 索引从0开始

tabhost.setcurrenttab(0); //从零开始

//通过标识来激活

// tabhost.setcurrenttabbytag("xxx1");

}

@override

public boolean oncreateoptionsmenu(menu menu) {

// inflate the menu; this adds items to the action bar if it is present.

getmenuinflater().inflate(r.menu.main, menu);

return true;

<!-- 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。
