在GridLayout kivy中添加多个GridLayouts

from kivy.uix.gridlayout import GridLayout
from kivy.app import App

class MyGridLayout(GridLayout):
    pass

class MyApp(App):
    def build(self):
        return MyGridLayout(cols=2)  # 设置主要GridLayout为2列

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

from kivy.uix.gridlayout import GridLayout
from kivy.app import App

class MyGridLayout(GridLayout):
    pass

class MyApp(App):
    def build(self):
        main_layout = MyGridLayout(cols=2)  # 设置主要GridLayout为2列

        # 创建子GridLayouts
        sub_layout1 = GridLayout(cols=1)
        sub_layout2 = GridLayout(cols=1)

        # 将子GridLayouts添加到主要GridLayout中
        main_layout.add_widget(sub_layout1)
        main_layout.add_widget(sub_layout2)

        return main_layout

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