C# 自定义 Fonts 在 Xamarin Forms (Android) 中不起作用。 Xamarin 4.8。 Windows 10, VS19

Question

I'm having an issue with Xamarin Forms 4.8 custom fonts.

I've followed the guides to the letter, that is:

-Loaded my font files (.ttf or.otf) into my shared directory and marked them as Embedded resources.

-Added the ExportFont outside of my namespace.

When I reference the font anywhere it just builds the standard font. Here is a snippet of code:

using System;
using System.Collections.Generic;
using Xamarin.Forms;
using Newtonsoft.Json.Linq;
using System.IO;
using System.Reflection;

[assembly: ExportFont("Stencil.ttf")]
[assembly: ExportFont("GreatVibes.otf")]
[assembly: ExportFont("Lobster-Regular.ttf", Alias= "MyFont")]

namespace BAAaM
{
    public partial class MainPage : ContentPage
    {

        public MainPage()
        {

            Grid topgrid = new Grid();
            topgrid.Children.Add(new Label { Text = "Test, please work", FontSize = 30, FontFamily = "Lobster-Regular" }, 0, 1);
this.Content = topgrid;
}
}
}

I've experimented placing the fonts into my Android directory, under assets but that doesn't work either. Is Xamarin overwriting whatever I do with standard Font as part of the built in label functions? I have no problems changing the text size.

Thanks,

M

Answer 1

I had this issue.

My solution: Changing file structure

FROM: Assets/Fonts/PoppinsBold.ttf

To: Fonts/PoppinsBold.ttf

You could refer to this official sample to check whether it works first.

Then I tested with your shared code:

    public FontPageXaml ()
    {
        InitializeComponent ();
        Grid topgrid = new Grid();
        topgrid.Children.Add(new Label { Text = "Test, please work", FontSize = 30, FontFamily = "Lobster-Regular" }, 0, 1);
        this.Content = topgrid;
    }

And it works:
