如何将我在KV文件中创建的ScrollView应用于我在Python文件中制作的手风琴

Accordion:
    orientation: 'vertical'
    ScrollView:
        size_hint_y: None
        height: root.height - accordion_tab_height
        GridLayout:
            cols: 1
            size_hint_y: None
            height: self.minimum_height
            # 添加需要滚动的内容

from kivy.uix.scrollview import ScrollView

from kivy.uix.accordion import Accordion, AccordionItem
from kivy.uix.label import Label

class MyAccordion(Accordion):
    def __init__(self, **kwargs):
        super(MyAccordion, self).__init__(**kwargs)
        
        # 创建ScrollView并添加到手风琴布局中
        scroll_view = ScrollView()
        accordion_item = AccordionItem(title='ScrollView Content')
        accordion_item.add_widget(scroll_view)
        self.add_widget(accordion_item)
        
        # 在ScrollView中添加内容
        content = GridLayout(cols=1, size_hint_y=None)
        content.bind(minimum_height=content.setter('height'))
        for i in range(20):
            label = Label(text=f'Label {i}')
            content.add_widget(label)
        scroll_view.add_widget(content)
