问题描述
I'm trying to make a application which should run in background and I need to know when is the volume button(-) pressed . 
我正在尝试制作一个应在后台运行的应用程序，我需要知道何时按下音量按钮（-）。
If it was pressed then I need to execute the back function ( NavigationService.GoBack(); ) 如果按下它，那么我需要执行后退功能（ NavigationService.GoBack(); ）
How can I do that? 我怎样才能做到这一点？
