/**
* 需求描述:
* 实现一个很简单的抽屉Demo
* 注意的问题:
* 1 打开抽屉的图标,打开后的界面都是布局在<SlidingDrawer/>中
* 2 在<SlidingDrawer/>中
* 使用:android:handle="@+id/handle_layout"
* 指定抽屉的把手
* 使用:android:content="@+id/content_layout"
* 指定打开抽屉后的View
* 3 SlidingDrawer一共有三个监听事件(见代码)
* 注意三者的执行顺序,总的原则是:
* 滑动完成后,打开(或者关闭)抽屉
* 所以:执行的顺序
* //1 setOnDrawerScrollListener
* //2 setOnDrawerOpenListener
* 或setOnDrawerCloseListener
