问题 Is it possible to superscript a label in Xamarin Forms? In HTML I would use the <sup> tag. I want to superscript the text "min". So I can have the text "5min" with the "min" part superscripted. 回答1: Thanks to Jason for his idea of using FormattedText property. But since it doesn't support binding of the text, I put 2 labels together in a StackLayout , the superscript text in mirco font size: <StackLayout Orientation="Horizontal" Spacing="0"> <Label Text="{Binding Minutes}"> <Label.FontFamily>
