简介
Container for a tabbed window view. This object holds two children: a set of tab labels that the
user clicks to select a specific tab, and a FrameLayout object that displays the contents of that
page. The individual elements are typically controlled using this container object, rather than
setting values on the child elements themselves.
TabHost ,标签视图的容器。容器包含两个孩子节点,一个用来存放一系列的标签,点击来选择对应的窗口;一个是FrameLayout用来存放页面具体内容。这些独立的元素通常用TabHost来控制,而不是在视图内部通过设置值来实现
