将 ScrollView 添加到 kivy 弹出窗口

Question

我正在尝试将 ScrollView 添加到在主界面上单击按钮时打开的弹出窗口。但是滚动视图没有正确显示内容。我该如何解决这个问题？

from kivy.uix.gridlayout import GridLayout
from kivy.uix.button import Button
from kivy.uix.popup import Popup
from kivy.uix.scrollview import ScrollView
from kivy.app import App
from kivy.core.window import Window

def btn_clicked(instance):
    layout_popup = GridLayout(cols=1, spacing=10, size_hint_y=None)
    layout_popup.bind(minimum_height=layout_popup.setter('height'))

    for i in range(0, 15):
        btn1 = Button(text=str(i), id=str(i))
        layout_popup.add_widget(btn1)

    root = ScrollView(size_hint=(1, None), size=(Window.width, Window.height))
    root.add_widget(layout_popup)
    popup = Popup(title='Numbers', content=root, size_hint=(1, 1))
    popup.open()

class TutorialApp(App):
    def build(self):
        g = GridLayout(cols=1)
        btn = Button(text='Click')
        btn.bind(on_press=btn_clicked)
        g.add_widget(btn)
        return  g


TutorialApp().run()

将size_hint_y=None 传递给按钮构造函数，它应该可以工作。
