[BadgeDrawable] Cannot set locale to badgedrawable. Taking application locale for default translation of number

[hiteshsarsava]

Description: When change the language of the App. The number format also gets translated into that selected language. I have issue where i want to keep the language of app in Arabic but number on badgeDrawable want to in English. As in below snippet, the NumberFormat.getInstance().format(getNumber()) taking the default locale. Developer can not set there any locale.

Expected behavior: Expected behavior is keep in english as that are numbers

Source code:

@NonNull
  private String getBadgeText() {
    // If number exceeds max count, show badgeMaxCount+ instead of the number.
    if (getNumber() <= maxBadgeNumber) {
      return NumberFormat.getInstance().format(getNumber());
    } else {
      Context context = contextRef.get();
      if (context == null) {
        return "";
      }

      return context.getString(
          R.string.mtrl_exceed_max_badge_number_suffix,
          maxBadgeNumber,
          DEFAULT_EXCEED_MAX_BADGE_NUMBER_SUFFIX);
    }
  }

Hi, currently the possible value range of a badge is 0~999, and I can't think of a case that a different locale may results in different number format. Can you give me a concrete example why this can be problematic?

@drchen As you can see the above screenshot. I want badge count in English Number. But when I change the language of my app in arabic it is automatically changes the number in arabic language number. How to restrict that ? As there is no option to set locale in badgeDrawable.
