python-3.x - KivyMD DatePicker 不随屏幕尺寸调整大小

Question

我不确定如何根据屏幕尺寸动态调整 MDDatePicker 的大小，它不能像 Labels 和 Buttons 那样正确调整，而是会不规律地调整。

我在 KivyMD 文档中找不到像在 Kivy 小部件中那样多的文档。

您必须单击“选择日期”按钮才能打开日期选择器

你可以尝试在 MDRaisedButton 下放置这个:

MDRaisedButton:
    size: root.width, root.height

或者您需要调整大小的地方。 size 命令格式为 size: x, y in kv lang
