Kivy Recycleview更新来自按钮，而不是应用构建方法

from kivy.app import App
from kivy.uix.button import Button
from kivy.uix.recycleview import RecycleView

class MyRecycleView(RecycleView):
    def __init__(self, **kwargs):
        super(MyRecycleView, self).__init__(**kwargs)
        self.data = [{'text': str(x)} for x in range(100)]  # 初始数据

    def update_data(self):
        # 更新数据
        self.data = [{'text': 'Updated ' + str(x)} for x in range(100)]
        self.refresh_from_data()  # 刷新Recycleview

class MyApp(App):
    def build(self):
        recycleview = MyRecycleView()
        button = Button(text='Update', size_hint=(None, None), size=(100, 50))
        button.bind(on_release=recycleview.update_data)  # 绑定按钮点击事件
        recycleview.add_widget(button)
        return recycleview

    MyApp().run()
