在 MAUI[Android] 中，Scrollview 在 maui.community.toolkit.popup 中不起作用

Question

我在内容页面尝试了相同的布局，它有效。它不仅仅在弹出窗口中工作。

下面是我的XAML代码结构。

<toolkit:Popup
    x:Class="MuniLogicMobile.View.ReportsPage"
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml
    xmlns:toolkit="http://schemas.microsoft.com/dotnet/2022/maui/toolkit"
    x:Name="popup"
    Color="Transparent">

    <Border
        Grid.Column="1"
        Stroke="{x:StaticResource Secondary}"
        StrokeThickness="2">
        <Border.StrokeShape>
            <RoundRectangle CornerRadius="10" />
        </Border.StrokeShape>
        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="Auto" />
            </Grid.RowDefinitions>
           
            <ScrollView
                Margin="10"
                HeightRequest="500"
                VerticalOptions="FillAndExpand">
                <VerticalStackLayout
                    Margin="10">
                </VerticalStackLayout>
            </ScrollView>
        </Grid>
    </Border>
</toolkit:Popup>

只需添加上面的布局并在弹出窗口中尝试。在 VerticalStackLayout 中添加更多项目。

我在Android平台遇到这个问题，没有在iOS中尝试过。

尝试设置滚动视图的高度，并且 将 HosrizontalOptions 和 VerticalOptions 设置为 Fill

两者单独或一起都不起作用。

我这边做了测试，但无法重现这个问题。我在 Android 模拟器（Pixel 5-Api 3）上进行了测试。

请参考我使用的以下代码，在我这边可以正常运行。

  <?xml version="1.0" encoding="utf-8" ?>

                <VerticalStackLayout
                    Margin="10">

                    <Label TextColor="Red" Text="1 FOR the most wild, yet most homely narrative which I am about to pen, I neither expect nor solicit belief.

In their consequences, these events have terrified -- have tortured -- have destroyed me. Yet I will not attempt to expound them. To me, they have presented little but Horror -- to many they will seem less terrible than barroques. Hereafter, perhaps, some intellect may be found which will reduce my phantasm to the common-place -- some intellect more calm, more logical, and far less excitable than my own, which will perceive, in the circumstances I detail with awe, nothing more than an ordinary succession of very natural causes and effects." />
