带有两个标签并同时滚动的Kivy ScrollView？

from kivy.app import App
from kivy.uix.scrollview import ScrollView
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.label import Label

class ScrollableLabelsApp(App):
    def build(self):
        # 创建根布局
        root = BoxLayout(orientation='vertical')

        # 创建ScrollView
        scroll_view = ScrollView()

        # 创建水平BoxLayout用于容纳两个标签
        label_layout = BoxLayout(orientation='horizontal', size_hint=(None, 1), width=300)

        # 添加标签到水平BoxLayout中
        label1 = Label(text='标签1', size_hint=(None, 1), width=150)
        label2 = Label(text='标签2', size_hint=(None, 1), width=150)
        label_layout.add_widget(label1)
        label_layout.add_widget(label2)

        # 将水平BoxLayout添加到ScrollView中
        scroll_view.add_widget(label_layout)

        # 将ScrollView添加到根布局中
        root.add_widget(scroll_view)

        return root

    ScrollableLabelsApp().run()
