抽屜式導航欄是工具欄下在Android中

我初來乍到的Android編程和目前工作的一個實踐的應用程序，或多或少的教程代碼拼湊而成。

現在我有導航工具欄下方的抽屜。我想重新調整xml層次結構，使其與Material Design指南保持一致，並在工具欄上方具有導航工具欄。這似乎是一個足夠簡單的任務，但對於我的生活，我似乎無法得到它。

任何人都可以提供任何建議嗎？

DrawerLayout是一個特殊的支持導航抽屜的。

沒有layout_gravity的子視圖是主視圖。子例如有layout_gravity例如android:layout_gravity="start"是導航抽屜。

這意味着DrawerLayout應該是頂級視圖組。換句話說，把你的佈局與ToolbarDrawerLayout。
