Change particular Edittext box locale to English if App locale is arabic

Question

I am working on a application which is having Arabic and English language like user can switch to any language between these two,My problem comes when i change my language to Arabic because i try to put any number in EditText view it automatically converts it into Arabic font.

I want to show english number font even when the language is set to arabic in edittext view.

This is my code which i used to change locale in my code :--

public class LocaleHelper {

    private static final String SELECTED_LANGUAGE = "Locale.Helper.Selected.Language";

    public static void onCreate(Context context) {
        String lang = getPersistedData(context, Locale.getDefault().getLanguage());
        setLocale(context, lang);
    }

    public static void onCreate(Context context, String defaultLanguage) {
        String lang = getPersistedData(context, defaultLanguage);
        setLocale(context, lang);
    }

    public static String getLanguage(Context context) {
        return getPersistedData(context, Locale.getDefault().getLanguage());
    }

    public static void setLocale(Context context, String language) {
        persist(context, language);
        updateResources(context, language);
    }

    private static String getPersistedData(Context context, String defaultLanguage) {
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
        return preferences.getString(SELECTED_LANGUAGE, defaultLanguage);
    }

    private static void persist(Context context, String language) {
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
        SharedPreferences.Editor editor = preferences.edit();

        editor.putString(SELECTED_LANGUAGE, language);
        editor.apply();
    }

    private static void updateResources(Context context, String language) {
        Locale locale = new Locale(language);
        Locale.setDefault(locale);

        Resources resources = context.getResources();

        Configuration configuration = resources.getConfiguration();
        configuration.locale = locale;

        resources.updateConfiguration(configuration, resources.getDisplayMetrics());
    }
}

Using StringFormat you can set different language than the application language. In my scenario I have to set Hindi as an application language but English for EditText, see below.

val lengthAConverted = String.format(Locale.ENGLISH,"%.2f", lengthA.toFloat())
dmh_s2_length_a_edit_text.text = lengthAConverted
