如何在KivyMD中为图片添加双击？

from kivy.uix.image import Image
from kivy.clock import Clock

class DoubleClickImage(Image):
    def on_touch_down(self, touch):
        if touch.is_double_tap:
            self.on_double_click()
        return super().on_touch_down(touch)

    def on_double_click(self):
        # 在这里添加双击图片后的操作
        pass

from kivymd.app import MDApp

class MyApp(MDApp):
    def build(self):
        return DoubleClickImage(source='path_to_image.png')

MyApp().run()
