Kivy Buildozer：AttributeError：“NoneType”对象没有属性“文本”答案

【问题标题】：Kivy Buildozer: AttributeError: 'NoneType' object has no attribute 'text'Kivy Buildozer：AttributeError：“NoneType”对象没有属性“文本”
【发布时间】：2020-04-03 01:33:43
【问题描述】：

我正在使用 Buildozer 测试 Kivy，以便为我的 Android 设备制作一个小应用程序。在我的电脑上，everythink 运行正常。但是当我想每次都用 Buildozer 创建 APK 时出现错误 AttributeError: 'NoneType' object has no attribute 'text'

我用谷歌搜索了很多次，但我找不到我的问题的答案。

有人给我提示吗？

会很棒。

谢谢！

.py 文件中的这行代码抛出错误

 #self.timestamp.text = timestamp
                if response['included'][x]['attributes']['triggered-by'] == 'standstill':
                    self.alert.text = "Verfügbarkeitsverlust seit"

我通过查看您发布的日志获得了此信息，该日志表明line 52 的main.py 文件中存在错误

【讨论】：

您好，谢谢。我试图取消注释此任务，但错误仍然发生并转到第 74 行“self.oee.text = oee” 我认为 .text 有问题。但不寻常的是，我的脚本可以在我的电脑上运行
据我所知，时间戳、oeee、可用性、性能等是标签的 id。所以你需要参考Widget的具体属性。比如可以做oeee.text或者oeee.width等，不能只引用oeee
你能再解释一下吗？我将变量编辑为例如“oee_”并在最后使用 self.oee.text = ... 进行标签操作，但这不是问题:(
for self.oee.text = oee 尝试使用 self.ids.oee.text = oee 看看是否成功 // 使用最新信息更新错误日志和代码
您好，感谢您的快速回复。我改变了这个，现在我得到另一个错误

【解决方案2】：

您好，感谢您的快速回复。我改变了这个东西，现在我得到一个新的错误

attributeerror 'super' object has no attribute '__getattr__' kivy

我在 Google 上搜索并将我的 super.init 编辑为 super(ConnectPage, self).__init__(**kwargs) 但是这个错误还是会出现。

你还有什么要告诉我的吗？谢谢！日志说：
