Xamarin.Forms change Default FontFamily in all App

Question

I added custom font:

[assembly: ExportFont("Roboto-Regular.ttf", Alias ="Roboto")]

Also in App.xaml :

        <Style TargetType="Label">
            <Setter Property="FontFamily" Value="Roboto"/>
        </Style>

And also can add for Entry and etc... But it is possible with one line of code change the Default Font Family which is initialized when u create the project? If is possible how?

Answer 1

You would need to create your controls for label,entry,picker,etc. with the default font family. I've created labelcontrol one for you

public class MyFontLabel : Label
{
    public MyFontLabel()
    {
       Style = Application.Current.Resources["FontLabelStyle"] as Style;
    }
}

style in app.xaml

<Style x:Key="FontLabelStyle" TargetType="Label">
  <Setter Property="FontFamily" Value="Roboto"/>
</Style>

Use it throughout

<local:MyFontLabel Text="My Text"/>
