问题描述
问题是弹出窗口弹出，但是它似乎内置在主屏幕后面。 我想这是由于要在“ on_enter”方法上调用，但无法解决此问题。
请注意，此“设置”按钮是从主屏幕而不是弹出窗口本身呈现的。
这是我的main.py：

这很奇怪，我无法弄清楚。
感谢您的帮助。干杯！
解决方法
问题在于on_enter()事件触发得太早，因此Popup在Main Screen之前被绘制。您可以通过在显示Popup之前添加很短的延迟来解决此问题。我更改了：
Factory.DiaDeRevisao().open()
收件人：
Clock.schedule_once(lambda dt: Factory.DiaDeRevisao().open())
将提供该延迟，并允许Popup显示在Screen上方。
