KIVY:我可以在scrollview里面有一个scrollview吗？

from kivy.app import App
from kivy.uix.scrollview import ScrollView
from kivy.uix.gridlayout import GridLayout
from kivy.uix.label import Label

class NestedScrollViewApp(App):
    def build(self):
        # 创建外层ScrollView
        outer_scrollview = ScrollView()

        # 创建内层ScrollView
        inner_scrollview = ScrollView()

        # 创建GridLayout作为内层ScrollView的子组件
        grid_layout = GridLayout(cols=1, size_hint_y=None)

        # 添加一些Label作为内层ScrollView的子组件
        for i in range(20):
            label = Label(text=f"Label {i}", size_hint_y=None, height=40)
            grid_layout.add_widget(label)

        # 设置GridLayout的高度，使其能够滚动
        grid_layout.bind(minimum_height=grid_layout.setter('height'))

        # 将GridLayout添加到内层ScrollView中
        inner_scrollview.add_widget(grid_layout)

        # 将内层ScrollView添加到外层ScrollView中
        outer_scrollview.add_widget(inner_scrollview)

        return outer_scrollview

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