Xamarin 为什么stacklayout内容会重叠？

我有一个带有滚动视图、堆栈布局、旋转木马视图和一些标签的内容页。当堆栈布局内容获得足够的元素时（如示例中通过复制元素所示），所有内容似乎都开始在旋转木马视图的顶部“分层”。图像似乎没有缩放，只是被截断。我对XAML相对缺乏经验，所以我可能做错了什么

<ContentPage.Content>
    <ScrollView>
        <StackLayout Margin="20">
            <cv:CarouselView ItemsSource="{Binding imgs}" 
                             x:Name="CarouselImgs">
               <cv:CarouselView.ItemTemplate>
                 <DataTemplate>
                   <Grid>
                     <Grid.RowDefinitions>

您是否正在使用此插件：？如果是这样，我建议您直接设置

cv:CarouselView

的

HeightRequest

以显示

CarouselView

您之所以说图像被截断是因为您将

Aspect

设置为

AspectFill

。它将缩放内容以填充视图的大小。可以剪裁部分内容以填充视图的边界

如果要缩放图像以适应图像大小，可以尝试

Fill

这肯定是HeightRequest属性…将其设置为更大是关键。非常感谢。
