ViewPager和Tabhost结合，可滑动的tabhost

有朋友反映资源下载下来有问题，我看了下，确实是，已更新下面文章中的代码和资源，现在可以好好的跑起来了，另外还改动了个小地方的逻辑，因为我在使用中出了点小错，需要的可以试下。另外，在使用中，注意下子activity中的上下文context,有可能有错，具体的东西在源码里有。

源码下载：https://github.com/qianjin/TestTabHost （csdn我传不上来，传到git去了）

可滑动的Tabhost,借助了surporrtV13,V4也差不多，一样的。

二者结合，当tabhost的tabbar点击的时候，viewPager滑动，滑动viewPager的时候，tabbar切换。tabbar的样式进行了重新布局，当然，你也可以自己定义自己的，详情看代码吧（下面有源码下载的地址）。

首先你要先在项目下建个libs把surporrtV13的jar包放进去。

效果图：
