class MyBoxLayout(BoxLayout):
    def __init__(self, **kwargs):
        super(MyBoxLayout, self).__init__(**kwargs)
        
        # 创建一个TextInput组件，并设置宽度和高度
        text_input = TextInput(size_hint=(None, None), size=(200, 100))
        
        self.add_widget(text_input)

class MyApp(App):
    def build(self):
        return MyBoxLayout()

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