网上已经有很多关于如何将TabHost的标签放在底部，这里就不说了

主要是把这些都做成框架，只需要提供图片和文字就可以实现这样的效果。

直接上图，代码解释的很清楚

程序的图片借用新浪微博，如有不妥，请告知

/**
 * <p>整个流程就像使用ListView自定BaseAdapter一样</p>
 * 
 * <p>如果要自定义TabHostActivity的Theme，并且不想要头部阴影
 * 一定要添加这个android:windowContentOverlay = null</p>
 * 
 * <p>如果想在别的项目里面使用TabHostActivity
 * 可以项目的属性里面找到Android，然后在Library部分添加这个项目(Api)
