However, I am still investigating to find a solution.

I found a code may be that will be helped.

private void overrideFonts(final Context context, final View v) {

  try {

    if (v instanceof ViewGroup) {

      ViewGroup vg = (ViewGroup) v;

         for (int i = 0; i < vg.getChildCount(); i++) {

         View child = vg.getChildAt(i);

         overrideFonts(context, child);

             }
    } else if (v instanceof TextView ) {

      ((TextView) v).setTypeface(Typeface.createFromAsset(context.getAssets(), "fonts/Vegur-R 0.602.otf"));

    }
   } catch (Exception e) {
  }
}
