Xamarin形式:UWP和Windows 8.1中的自定义字体 [英] Xamarin forms: Custom Fonts in UWP and Windows 8.1

问题描述

我正在开发一个使用font.otf文件的应用程序.我的应用程序将在android，ios，Windows 10和Windows 8.1上运行.我需要为标签创建样式以设置字体系列. 对于android和ios，我引用了链接

I am developing an app in which I am using a font.otf file. My app will run on android, ios, windows 10 and windows 8.1. I need to create styles for my labels to set font family. For android and ios I referenced this link

我在这样的xaml页面中尝试过-

I tried in xaml page like this-

<Label.FontFamily>
        <OnPlatform x:TypeArguments="x:String">
            <OnPlatform.iOS></OnPlatform.iOS>
            <OnPlatform.Android>Lobster-Regular.ttf#Lobster-Regular</OnPlatform.Android>
            <OnPlatform.WinPhone></OnPlatform.WinPhone>
        </OnPlatform>
    </Label.FontFamily>

new Label {
    Text = "Hello, Forms!",
    FontFamily = Device.OnPlatform (
        null,
        null,
        @"\Assets\Fonts\Lobster-Regular.ttf#Lobster-Regular"
                 // Windows Phone will use this custom font
    )
}

但是，当我运行我的应用程序时，Windows 10和8.1的字体没有设置.

But when I run my app Font does not set for Windows 10 and 8.1.

如何为Windows 10和8.1设置字体系列. 还是有一种更有效的方式来覆盖所有平台来应用字体系列?

How can I set font family for windows 10 and 8.1. Or is there more efficient way to apply font family with covering all the platforms?

推荐答案

注意:存在一个错误，其中

Note: there is a bug where custom fonts do not work if you are using a NavigationPage

在Windows 8.1/UWP上，自定义字体不需要自定义渲染器； Xamarin示例代码仅存在几个错误:

You do not need a custom renderer for custom fonts on Windows 8.1/UWP; the Xamarin sample code simply has a couple of mistakes:

• 使用正斜杠('/')代替
• 路径应为[font file]#[font name]的形式(无字体样式，例如'regular')

• Use a forward slash ('/') instead
• The path should be in the form of [font file]#[font name] (without the font style, e.g. 'regular')

所以这种情况下的路径实际上应该是

So the path in this case should actually be

"Assets/Fonts/Lobster-Regular.ttf#Lobster"

您还可以在Xaml中使用它

And you can also use this in Xaml

<OnPlatform.WinPhone>Assets/Fonts/Lobster-Regular.ttf#Lobster</OnPlatform.WinPhone>

确保字体文件包含在BuildAction:Content项目中，并且可以正常工作.

Make sure your font file is included in your project with BuildAction:Content and it should work.
