也许有人知道为什么在 PC 上运行它不会从 las 6 行中产生这个错误？正是这个 AttributeError: 'super' object has no attribute 'getattr' ？ 如何更改 main 中的代码以使其在 android 上运行？或者其他问题的解决方案？

解决方法
我怀疑问题出在时间上。 Android 设备可能比您的 PC 慢一点，导致 ids 实例中的 GUI 在您调用 WHJoy() 时未准备好。我建议从 Clock.schedule_interval() 方法中删除 __init__() 调用并稍微延迟这些间隔调用的开始。也许从 on_start() 的 App 方法开始：
class GUIApp(App):
def build(self):
return GUI()
def on_start(self):
Clock.schedule_interval(self.root.update,1/30.0)
Clock.schedule_interval(self.root.change_color,1 / 1)
作为测试，只是为了看看时间是否是罪魁祸首，请尝试运行：
class GUIApp(App):
def build(self):
Clock.schedule_once(self.start_intervals,3)
return GUI()
def start_intervals(self,dt):
Clock.schedule_interval(self.root.update,1 / 1)
此代码在开始您的间隔（3 秒）之前会造成极大的延迟。当然，这对于您的最终代码来说是不可接受的，但是如果这消除了错误，那么时间就是问题。
