如何使用kivymd上的按钮从列表小部件中删除项目

from kivymd.app import MDApp
from kivymd.uix.list import OneLineListItem
from kivymd.uix.button import MDIconButton
from kivy.uix.boxlayout import BoxLayout

class MyApp(MDApp):
    def delete_item(self, instance):
        # 在这里编写删除项目的逻辑
        pass

class MyApp(MDApp):
    def build(self):
        layout = BoxLayout(orientation='vertical')
        
        # 创建一个列表小部件
        list_item = OneLineListItem(text='项目1')
        
        # 创建一个删除按钮
        delete_button = MDIconButton(icon='delete', on_release=self.delete_item)
        
        # 将列表小部件和按钮添加到布局中
        layout.add_widget(list_item)
        layout.add_widget(delete_button)
        
        return layout

class MyApp(MDApp):
    def run(self):
        layout = BoxLayout(orientation='vertical')
        # ... 省略其他代码 ...
        
        return layout

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