Python 3和Kivy:只对双击“非”单击做出反应

from kivy.app import App
from kivy.uix.label import Label
from kivy.clock import Clock


class DoubleClickApp(App):
    def __init__(self, **kwargs):
        super(DoubleClickApp, self).__init__(**kwargs)
        self.click_count = 0

    def build(self):
        self.label = Label(text="Click me!")
        self.label.bind(on_touch_down=self.on_click)
        return self.label

    def on_click(self, instance, touch):
        if touch.is_double_tap:
            self.label.text = "Double Clicked!"
        else:
            self.click_count += 1
            Clock.schedule_once(self.check_click, 0.3)

    def check_click(self, dt):
        if self.click_count == 1:
            self.label.text = "Single Clicked!"
        self.click_count = 0

    DoubleClickApp().run()
