不能多次设置内容 xaml

Question

我正在使用 Xamarin 和 xaml 来定义我的视图。我收到了一个我不理解的错误。

一个 ScrollView 不能有多个子级，因此错误定义内容不止一次。

因此，要解决此问题，您可以将内容封装在 StackLayout 中：

  <ScrollView>
    <StackLayout>
            <Frame x:Name="reprint" Padding="40" IsClippedToBounds="False"   CornerRadius="4">
                <telerikPrimitives:RadBorder BorderThickness="8" CornerRadius="10">

                    <StackLayout>

                        <Label Text=" Label"></Label>
                        <Label Text="Allows the User to reprint a label."></Label>

                        <telerikInput:RadButton BackgroundColor="#343C41" TextColor="White" Text="Label Reprint" x:Name="btnLabelReprint" Clicked="BtnLabelReprint_Clicked">

                        </telerikInput:RadButton>
                    </StackLayout>

                </telerikPrimitives:RadBorder>
            </Frame>
            <Frame x:Name="warehouseTransferr" Padding="40"    CornerRadius="4">
                <telerikPrimitives:RadBorder BorderThickness="8" CornerRadius="10">

                    <StackLayout>

                        <Label Text="Ware House Transfer"></Label>
                        <Label Text="Allows users to transfer from warehouse to waehouse"></Label>

                    <telerikInput:RadButton BackgroundColor="#343C41" TextColor="White" Text="Warehouse Transfer" x:Name="btnWarehouseTransfe" Clicked="BtnWarehouseTransfe_Clicked">

                            </telerikInput:RadButton>
                    </StackLayout>

                </telerikPrimitives:RadBorder>
            </Frame>
        </StackLayout>
    </ScrollView>
