我正在尝试创建一个kivy应用程序。 应用程序的工作原理如下:
在我的计时器下面有3个按钮,暂停,继续和停止。 当使用MQTT命令启动和暂停计时器时,我似乎无法让我的resume按钮正常工作,如果单击pause按钮后还有26秒,我希望我的计时器从此点恢复。相反,它从头开始

我如何才能使我的计时器不会重置每次我点击我的简历按钮?你知道吗
编辑:设法解决我的问题!
我做了一个事件(self.event = Clock.schedule_interval(self.tick,1)
),有两个按钮可以暂停和继续。
我使用暂停按钮(Clock.unschedule(self.event)
)取消计划事件,使用恢复按钮(Clock.schedule_once(self.event)
)重新计划计时器。你知道吗
您不能使用
Clock.unschedule(self.tick)
取消Kivy时钟事件的计划。请参考下面的例子。你知道吗Kivy Clock » Unscheduling
时间表
替换

计划外
这样你就可以使用 或者
