如何从class A向GridLayout小部件添加另一个标签？

您可以使用在

kv

中指定的

id

：

class A(Screen):
    def do_some_stuff(self):
        self.ids.someID.add_widget(Label(text="I was told to do some stuff"))

谢谢，这个答案真的很有帮助！

class A(Screen):
    def do_some_stuff(self):
        print("I was told to do some stuff")

class RootWidget(ScreenManager):
    pass
class MainApp(App):
    def build(self):
        return RootWidget()

class A(Screen):
    def do_some_stuff(self):
        self.ids.someID.add_widget(Label(text="I was told to do some stuff"))
