Python Kivy条件布局

Question

I am building a Kivy application which will serve as a SmartMirror. The mirror is supposed to go into the main menu, which I already programmed, if a certain event fired, otherwise the screen should remain black. This means on that event I need to load all the body.kv file and after a certain timeout the body should be unloaded.

Builder.load_file('smartmirror.kv')
Builder.load_file('headerspace.kv')
Builder.load_file('bodyspace.kv')
Builder.load_file('footerspace.kv')

if __name__ == '__main__':
    app = SmartMirrorApp()
    app.run()

How do I do this the best way?

Have a look https://kivy.org/docs/api-kivy.uix.screenmanager.html .

ScreenManager can manage your blank/main screen transitions
