Python 在Kivy中使用jsonstore

我在尝试自学如何使用jsonstore的同时创建了一个GUI。我没有声誉点来添加评论，所以我在这里问我的问题。我想我已经记下了基本想法，但由于某些原因，我无法将数据保存到json文件中。我得到以下错误：

AttributeError: 'NoneType' object has no attribute 'text'

我试着按照文档进行操作，但我看不到任何地方可以解释我做错了什么

您的代码有几个问题，但主要问题是您不知道如何将任何.kv小部件公开给.py，最简单的方法之一是在尝试时使用ObjectProperty，但该属性未链接到小部件，为了简单起见，我更喜欢在.kv中创建

另一方面，我建议您避免滥用try，除非因为它隐藏了错误，最好是验证

另一个错误是您正在覆盖.json中profile的值，其思想是将所有内容保存在一个文件中

考虑到上述情况，解决方案是：

*.py
