SlidingDrawer

 一  SlidingDrawer 这个类，也就是所谓的"抽屉"类。它的用法很简单，要包括handle ,和content .handle 就是当你点击它的时候，content 要么抽抽屉要么关抽屉。这是上下拉抽屉的效果，将 SlidingDrawer属性设置为android:orientation="vertical"即可这是左右拉抽屉的效果，将 SlidingDrawer属性设置为android:orientation="horizontal"即可。

二、重要属性
    android:allowSingleTap：指示是否可以通过handle打开或关闭
    android:animateOnClick：指示是否当使用者按下手柄打开/关闭时是否该有一个动画。
    android:content：隐藏的内容
    android:handle：handle(手柄)
    
三、重要方法

　　animateClose()：关闭时实现动画。
        close()：即时关闭
        getContent()：获取内容

　　isMoving()：指示SlidingDrawer是否在移动。
　　isOpened()：指示SlidingDrawer是否已全部打开
　　lock()：屏蔽触摸事件。
　　setOnDrawerCloseListener(SlidingDrawer.OnDrawerCloseListener onDrawerCloseListener)：SlidingDrawer关闭时调用
　　unlock()：解除屏蔽触摸事件。

　　toggle()：切换打开和关闭的抽屉SlidingDrawer。

上面例子的布局文件：

      还有注意的是：
       SlidingDrawer should be used as an overlay inside layouts. This means SlidingDrawer should only be used inside of a FrameLayout or a RelativeLayout for instance,如果显示的时候不正常，考虑上面的原因。
