我剛剛在最近包含在支持庫中的新的DrawerLayout玩弄。我已經實現了一個簡單的示例與多個抽屜，而我使用START和END作爲gravities它的所有工作就像一個魅力，但當試圖添加一個抽屜的頂部或底部gravities它崩潰。使用頂部和底部重力時，Android DrawerLayout失敗
是否可以使用它從頂部和/或底部滑動抽屜？
下面是我的活動和工作狀態下的XML佈局的完整代碼;如果我試圖改變這一點：
<ListView android:id="@+id/right_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="end"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
android:background="#007799"/>
到這個（在layout_width變動公告，layout_height和layout_gravity）：
<ListView android:id="@+id/right_drawer"
android:layout_width="match_parent"
android:layout_height="300dp"
android:layout_gravity="bottom"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
android:background="#007799"/>
而行：
this.drawer.openDrawer(GravityCompat.START);
信息這一個：
this.drawer.openDrawer(Gravity.BOTTOM);
是當我ge t出現以下錯誤：

任何線索爲什麼我不能使用這個其他的比重？
謝謝！

我問@羅馬nurik這個在他的[G + （https://plus.google.com/113735310430199015092/posts/bjiNbjAFsT2）關於DrawerLayout的介紹，他指出：_「不，絕對不打算與垂直重力一起使用」_所以我想這沒有意義試圖讓這個工作。任何替代實施垂直抽屜？ – luixal
mabe你可以使用SlidingDrawer？ –
看看https://github.com/Ali-Rezaei/SlidingDrawer，它可以通過幾行代碼從任何一側滑動。 – Ali
