python kivy，我想在滚动视图的按钮上打印按钮的文本

from kivy.app import App
from kivy.uix.scrollview import ScrollView
from kivy.uix.gridlayout import GridLayout
from kivy.uix.button import Button

class MyScrollView(ScrollView):
    def __init__(self, **kwargs):
        super(MyScrollView, self).__init__(**kwargs)
        self.layout = GridLayout(cols=1, spacing=10, size_hint_y=None)
        self.layout.bind(minimum_height=self.layout.setter('height'))
        self.add_widget(self.layout)

class MyScrollView(ScrollView):
    def __init__(self, **kwargs):
        # 省略初始化代码

    def add_button(self, text):
        button = Button(text=text)
        button.bind(on_release=self.print_button_text)
        self.layout.add_widget(button)

    def print_button_text(self, button):
        print(button.text)

class MyApp(App):
    def build(self):
        scroll_view = MyScrollView()
        for i in range(10):
            scroll_view.add_button(f"Button {i+1}")
        return scroll_view

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