抽屉式导航栏是工具栏下在Android中

我初来乍到的Android编程和目前工作的一个实践的应用程序，或多或少的教程代码拼凑而成。

现在我有导航工具栏下方的抽屉。我想重新调整xml层次结构，使其与Material Design指南保持一致，并在工具栏上方具有导航工具栏。这似乎是一个足够简单的任务，但对于我的生活，我似乎无法得到它。

任何人都可以提供任何建议吗？

DrawerLayout是一个特殊的支持导航抽屉的。

没有layout_gravity的子视图是主视图。子例如有layout_gravity例如android:layout_gravity="start"是导航抽屉。

这意味着DrawerLayout应该是顶级视图组。换句话说，把你的布局与ToolbarDrawerLayout。
