我正在使用Xamarin forms控件来开发synfusion。

我需要一个页面，该页面在弹出页面中有图像上传，但是图像不是从项目图像文件夹上传的。

调试之后，似乎主要的问题是标记及其属性

所以请建议我该用什么。

<sfPopup:SfPopupLayout x:Name="popupLayout">
    <sfPopup:SfPopupLayout.PopupView>
            <sfPopup:PopupView HeaderTitle="Popup Imagess"
                           Animationmode="None"
                           AutoSizeMode="None"
                           HeightRequest="{OnPlatform UWP={OnIdiom Phone=250,Tablet=290,Desktop=290},Android=350,iOS=250}" >

                <sfPopup:PopupView.ContentTemplate>
                <DataTemplate>
                    <syncfusion:SfListView  x:Name="listView" Orientation="Horizontal" Padding="10,10,10"
