In the Python file, import the usual package to use Kivy.

Also, import the screen manager package.

Define the class for the buttons' rules.

Define the class for the root widget.

In the __init__() method, create and add two screens to the root widget with different content for each one.

With the help of the following code, add two buttons that will help you switch between the two screens:from kivy.app import App from kivy.lang import Builder from kivy.uix.label import Label from kivy.uix.button import Button from kivy.uix.boxlayout import BoxLayout from kivy.uix.screenmanager import Screen class MButton(Button): pass class MyW(BoxLayout): def __init__(self, **kwargs): super(MyW, self).__init__(**kwargs) s = Screen(name="Hello1") s.add_widget(Label(text="src1")) self.ids.sm.add_widget(s) s = Screen(name="Hello2") s.add_widget(Label(text="src2")) self.ids.sm.add_widget(s) self.ids.buttons.add_widget(MButton( text="Hello1")) self.ids.buttons.add_widget(MButton( text="Hello2")) class e1App(App): def build(self): return MyW() if __name__ == '__main__': e1App().run()
