如何在Kivy应用中为不同的ListView实例设置不同的属性？

from kivy.uix.listview import ListView

class MyListView(ListView):
    pass

<MyListView>:
    # 设置MyListView的样式和属性
    size_hint: None, None
    size: 200, 200
    background_color: 1, 1, 1, 1

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout

class MyApp(App):
    def build(self):
        layout = BoxLayout(orientation='vertical')

        # 创建不同的MyListView实例，并设置不同的属性
        listview1 = MyListView()
        listview1.background_color = 1, 0, 0, 1

        listview2 = MyListView()
        listview2.background_color = 0, 1, 0, 1

        layout.add_widget(listview1)
        layout.add_widget(listview2)

        return layout

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