隐藏式抽屉SlidingDrawer（无法实现垂直）
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
? SlidingDrawer配置上采用了水平展開或垂直展開兩種（android:orientation）方式，在XML里必須指定其使用的android:handle與android:content，前者委托要展開的圖片（Layout配置），后者則是要展開的Layout Content。
運行結果：

但是在實現垂直方向的變化時。將
<SlidingDrawer??????????android:id="@+id/sd"??????????android:layout_width="fill_parent"??????????android:layout_height="fill_parent"??????????android:handle="@+id/layout1"??????????android:content="@+id/myContent1"??????????android:orientation="vertical"??????????>?改變后無法實現。經過一些改變gravity的方法還是沒有找出問題所在。
