我需要修复 mddialog，以便小部件按钮看起来像 在下面的弹出对话框中。有趣的是哪个容器将容纳小部件并使其看起来在一层中。 我试过 MDBoxLayout 但它显示为两层。

<MDPopup@mddialog>
    auto_dismiss: True 
    size_hint: (.9,.4)
    title: "Dialog Title Header"
    text: "Some Dialog Text."
    MDBoxLayout: # Need a Fix for this here !!!!
        md_bg_color: 1,1
        size_hint: None,None
        height: root.height
        width: root.width
        MDFlatButton:
            text: "CANCEL"
            pos_hint: {"center_x":.7}
        MDRectangleFlatButton:
            text: "Yes it's Neat"
            pos_hint: {"center_x": .1}

<MyLayout>
    BoxLayout:
        orientation: 'vertical'
        size: root.width,root.height


        mdscreen:

            MDLabel:
                id: my_label
                text: "Some Struff"
                pos_hint: {'center_x': .95,'center_y': .4}
            MDRaisedButton:
                text: "Popup"
                pos_hint: {'center_x': .5,'center_y': .5}
                font_size: 32
                on_release: Factory.MDPopup().open()


        ''')

class MyLayout(Widget):
        
    pass

class mddialogBoxApp(MDApp):
    def build(self):
        self.theme_cls.theme_style = "Light"
        self.theme_cls.primary_palette = "Indigo"
        self.theme_cls.accent_palette = "Green"
        return MyLayout()


if __name__ == '__main__':
    mddialogBoxApp().run()
