Question

我的应用程序具有3个屏幕，可通过“ ActionBar”进行浏览。我在kv文件中命名了每个屏幕，一个是“跟踪”另一个是“ pess”。这是我需要帮助的两个。

我在“ pess”屏幕类中创建了一个单选按钮小部件（下图），因此可以添加电子邮件地址。

在“跟踪”屏幕课程中，我拥有了要通过电子邮件发送的所有数据，但是我认为事情已经变得过于复杂了。我想将活动的单选按钮从“ pess”屏幕链接到“ track”屏幕def发送功能...

我的Main.py看起来像这样

{{ product.featured_image | img_url | img_tag }}

我的代码运行得很好，但是所有发送信息的电子邮件都是硬编码的。我想为用户提供输入电子邮件地址并将其发送到该地址的选项。

我添加了Checkboxes类，每次添加名称和电子邮件地址并单击“ Save Email”时都会创建该复选框。它被分组，因此它们是单选按钮。

我似乎无法将电子邮件地址连接到Trackers类上的send函数...我希望所有这些都有意义。我可能为我自己使事情变得过于复杂。我可以帮忙。谢谢。

Kivy：在我的代码中正确实现“单选按钮”。 Python 3
