Using custom font in android TextView using xml

Question

I have added a custom font file to my assets/fonts folder. How do I use it from my XML?

I can use it from code as follows:

TextView text =

UPDATE: https://github.com/chrisjenx/Calligraphy appears to be a superior solution to this.

Maybe you can use reflection to inject/hack your font into the static list of available fonts when your application is created? I am interested in feedback from others if this is a really, really bad idea or if this is a great solution — it seems it is going to be one of those extremes...

I was able to inject my custom typeface into the list of system typefaces with my own font family name, then specifying that custom font family name ("brush-script") as the value of android:FontFamily on a standard TextView worked on my LG G4 running Android 6.0.

public class MyApplication extends android.app.Application
{
    @Override
    public void onCreate()
    {
        super.onCreate();

        Typeface font = Typeface.createFromAsset(this.getResources().getAssets(),"fonts/brush-script.ttf");
        injectTypeface("brush-script", font);
    }

    private boolean injectTypeface(String fontFamily, Typeface typeface)
    {
        try
        {
            Field field = Typeface.class.getDeclaredField("sSystemFontMap");
            field.setAccessible(true);
            Object fieldValue = field.get(null);
            Map map = (Map) fieldValue;
            map.put(fontFamily, typeface);
            return true;
        }
        catch (Exception e)
        {
            Log.e("Font-Injection", "Failed to inject typeface.", e);
        }
        return false;
    }
}
