PYTHON + KIVYMD / KIVY |滚动视图仅在屏幕的一半上，但在导航抽屉中使用时可以正常工作

Question

这是问题的图片。如您所见，左侧图片具有完全可用的滚动视图，而右侧图片仅在屏幕的下半部分显示滚动视图。

不确定这里出了什么问题。我试着来回移动意向水平，出于某种原因，它拒绝将任何东西放在赤道以上

Snippit of the KV code from the not working part:

Answer 1

所以我发现了问题（张贴以防其他人遇到同样的问题）。

屏幕：容器：容器盒子布局：编号：容器方向：'vertical' MD工具栏：标题：“尝试” anchor_title: "中心"

     #   right_action_items: [["check", lambda x: app.show_alert_dialog_save(), 'Save']]
        left_action_items: [["keyboard-backspace", lambda x: app.show_alert_dialog_back(), 'Back']]

    Widget: # <----- After removing this the ScrollView fills the whole screen not just half :)

    ScreenManager:
        id: screen_manager

        Screen:
            name: 'innlogget_trym_alarm'
            id: trym
