SlidingDrawer

 一  SlidingDrawer 這個類，也就是所謂的"抽屜"類。它的用法很簡單，要包括handle ,和content .handle 就是當你點擊它的時候，content 要麼抽抽屜要麼關抽屜。這是上下拉抽屜的效果，將 SlidingDrawer屬性設置爲android:orientation="vertical"即可這是左右拉抽屜的效果，將 SlidingDrawer屬性設置爲android:orientation="horizontal"即可。

二、重要屬性
    android:allowSingleTap：指示是否可以通過handle打開或關閉
    android:animateOnClick：指示是否當使用者按下手柄打開/關閉時是否該有一個動畫。
    android:content：隱藏的內容
    android:handle：handle(手柄)
    
三、重要方法

　　animateClose()：關閉時實現動畫。
        close()：即時關閉
        getContent()：獲取內容

　　isMoving()：指示SlidingDrawer是否在移動。
　　isOpened()：指示SlidingDrawer是否已全部打開
　　lock()：屏蔽觸摸事件。
　　setOnDrawerCloseListener(SlidingDrawer.OnDrawerCloseListener onDrawerCloseListener)：SlidingDrawer關閉時調用
　　unlock()：解除屏蔽觸摸事件。

　　toggle()：切換打開和關閉的抽屜SlidingDrawer。

      還有注意的是：
       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,如果顯示的時候不正常，考慮上面的原因。
