將Kivy的設置用作屏幕

Question

我試圖用Settings屏幕創建應用程序（在ScreenManager中）。如何將Settings放入Screen，以便我可以將Screen放入ScreenManager，因此當Screen導航到Settings實例時，它會被隱藏起來，並且會被導航離開它嗎？

以下是關於如何使用2個屏幕的screenmanager的基本示例。

from kivy.app import App 
from kivy.uix.screenmanager import Screen,ScreenManager 
from kivy.uix.boxlayout import BoxLayout 
from kivy.uix.button import Button 
from kivy.uix.label import Label 



class ScreenOne(Screen): 

    def __init__(self,**kwargs): 
     super(ScreenOne,self).__init__(**kwargs) 
     self.box = BoxLayout(orientation='vertical') 

     self.label1 = Label(text="One label on screen 1") 
     self.label2 = Label(text="Another label label") 

     self.button = Button(text="Go to screen 2") 
     self.button.bind(on_press=self.change_screen) 

     self.box.add_widget(self.label1) 
     self.box.add_widget(self.label2) 

     self.box.add_widget(self.button) 

     self.add_widget(self.box) 

    def change_screen(self,*args): 
     self.manager.current = 'screen2' 



class ScreenTwo(Screen): 
    def __init__(self,**kwargs): 
     super (ScreenTwo,self).__init__(**kwargs) 

     self.box = BoxLayout(orientation='vertical') 

     self.label1 = Label(text="One label on screen 2") 
     self.label2 = Label(text="Another label label") 

     self.button = Button(text="Go to screen 1") 
     self.button.bind(on_press=self.change_screen) 

     self.box.add_widget(self.label1) 
     self.box.add_widget(self.label2) 

     self.box.add_widget(self.button) 

     self.add_widget(self.box) 

    def change_screen(self,*args): 
     self.manager.current = 'screen1' 



class MyApp(App): 
    def __init__(self,**kwargs): 
     super(MyApp,self).__init__(**kwargs) 
     self.sm = ScreenManager() 

     self.sm.add_widget(ScreenOne(name = "screen1")) 
     self.sm.add_widget(ScreenTwo(name = "screen2")) 


    def build(self): 
     return self.sm 



if __name__ == "__main__": 
    MyApp().run()
