问题描述
我希望这个 drawerLayout(波纹管照片)总是像三星多窗口侧边栏一样打开。
直到现在我可以在应用程序中打开这个 drawerLayout(sidebar)。请给出能够从任何地方(我的意思是从任何其他应用程序甚至从设备的主屏幕)打开此 draweLayout(侧边栏)的说明。
提前致谢。
这是我的drayerLayout XML 文件:

解决方法
这不能通过在每个活动中做一些修改来实现全局性
您可以创建一个新类,该类将具有初始化导航的方法,将导航视图移动到单独的 xml 文件并将该文件包含在每个活动中,并在每个活动中调用初始化方法
您可以尝试使用此库 https://github.com/mikepenz/MaterialDrawer 将大多数 xml 代码移至 java,这样您就不必在每个活动中添加 DrawerLayout,但您可以自行选择,如果可以,最好跳过使用 3rd 方库
如果您使用的是图书馆,那么您可以按照以下示例进行操作

ProfileDrawerItem section = new ProfileDrawerItem()
