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，而是不规则地调整。

我在Kivy小部件中找不到太多的KivyMD文档。

您必须单击“选择日期”按钮以打开日期选择器

    NavigationLayout:
        id: nav_layout
        MDNavigationDrawer:
            NavigationDrawerIconButton:

                left_action_items: [['menu', lambda x: root.ids.nav_layout.toggle_nav_drawer()]]

            MDRaisedButton:

                pos_hint: {"x": 0.35, "top": 0.6}

您可以在MDRaisedButton下尝试：

MDRaisedButton:
    size: root.width, root.height

或您需要调整大小的地方。 size命令的格式为size: x, y（在kv lang中

KivyMD DatePicker不会随着屏幕尺寸调整大小
