SlidingPaneLayout的基本使用

SlidingPaneLayout是V4包中新添加的组件,可以实现两列面板的切换。说先来看看API文档的说明:

1
SlidingPaneLayout provides a horizontal, multi-pane layout for use at the top level of a UI. A left (or first) pane is treated as a content list or browser, subordinate to a primary detail view for displaying content.

SlidingPanelLayout为在UI最上层的使用提供了一个水平的,多个面板的布局。左边的面板可以看作是一个内容列表或者是浏览,右边的面板的任务是显示详细的内容。

SlidingPaneLayout类也是直接继承于ViewGroup类,所以这个类也是当作容器类使用,在使用时通常可以和Fragement组件一起使用。下面是一个xiaoDemo,左边是网站url,右边显示网站。

首先是各个布局文件:
