我编写了以下代码,以尝试在网页中显示几行HTML:

我有这个XAML:

 <ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:local="clr-namespace:Japanese;assembly=Test"
    x:Class="Test.HelpCards"
    x:Name="HelpCards"
    Title="Help ▹ Cards Tab">
    <ContentPage.Content>
        <ScrollView>
            <StackLayout Spacing="10" Margin="20">
               <WebView x:Name="Browser" />
            </StackLayout>
        </ScrollView>
    </ContentPage.Content>
</ContentPage>

    public HelpCards()
    {
        InitializeComponent();
        var htmlSource = new HtmlWebViewSource();
        htmlSource.Html = @"<html><body>
        <h1>ABC</h1>
        <p>DEF</p>
        </body></html>";
        Browser.Source = htmlSource;
    }

但是,在运行代码时,我只会看到空白页。

是否有人对可能出什么问题有任何想法?

最佳答案

确保为WebView指定layout-options。

<ContentPage.Content>
    <ScrollView> <!-- ScrollView not needed as WebView has inbuilt scrolling behavior -->
        <StackLayout Spacing="10" Margin="20">
           <WebView x:Name="Browser" VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand" />
        </StackLayout>
    </ScrollView>
</ContentPage.Content>
