Adding to rischan's answer.

I edited 'mi' directly as those are my drawer menu titles. Then I changed the s.setSpan 1st parameter to use a custom class CustomTypefaceSpan.

    // Navigation View
    NavigationView navigationView = (NavigationView) 
    findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

    Menu m = navigationView .getMenu();

    Typeface tf1 = Typeface.createFromAsset(getAssets(), "font/Gotham Narrow Extra Light.otf");

    for (int i=0;i

CustomTypefaceSpan Class:

package my.app;
import android.graphics.Paint;
import android.graphics.Typeface;
import android.text.TextPaint;
import android.text.style.TypefaceSpan;

public class CustomTypefaceSpan extends TypefaceSpan {

    private final Typeface newType;

    public CustomTypefaceSpan(String family, Typeface type) {
        super(family);
        newType = type;
    }

    @Override
    public void updateDrawState(TextPaint ds) {
        applyCustomTypeFace(ds, newType);
    }

    @Override
    public void updateMeasureState(TextPaint paint) {
        applyCustomTypeFace(paint, newType);
    }

    private static void applyCustomTypeFace(Paint paint, Typeface tf) {
        int oldStyle;
        Typeface old = paint.getTypeface();
        if (old == null) {
            oldStyle = 0;
        } else {
            oldStyle = old.getStyle();
        }

        int fake = oldStyle & ~tf.getStyle();
        if ((fake & Typeface.BOLD) != 0) {
            paint.setFakeBoldText(true);
        }

        if ((fake & Typeface.ITALIC) != 0) {
            paint.setTextSkewX(-0.25f);
        }

        paint.setTypeface(tf);
    }
}

Can't believe how complicated it is just to change the fonts for the menu.
