在应用程序中更改语言后，数字文本的格式不会更改

Question

我有两种语言的应用程序（英语和波斯语）。我已经为波斯语言使用了自定义字体。当语言应用程序更改为英语时，数字文本也将保留为波斯格式。我已经使用calligraphy3库来设置自定义字体。配置字体和设置语言是我的Application类。

     public class MyApplication extends MultiDexApplication {
        private Locale locale = null;

        @Override
        public void onConfigurationChanged(Configuration newConfig) {
            super.onConfigurationChanged(newConfig);
            Configuration config=new Configuration(newConfig);
            if (locale != null) {
                config.locale = locale;
                Locale.setDefault(locale);
                getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());
            }
        }

        @Override
        public void onCreate() {
            super.onCreate();

            /* initialize calligraphy3 library */
            ViewPump.init(ViewPump.builder()
                    .addInterceptor(new CalligraphyInterceptor(
                            new CalligraphyConfig.Builder()
                                    .setDefaultFontPath("fonts/isans.ttf")
                                    .setFontAttrId(R.attr.fontPath)
                                    .build()))
                    .build());

            /* for localization app */
            Configuration conf = getBaseContext().getResources().getConfiguration();
            Configuration config = new Configuration(conf);
            Log.e(TAG, "pref lag: " + prefHelper.getMyLanguage());
            String lang = prefHelper.getMyLanguage();

            if (!"".equals(lang) && !config.locale.getLanguage().equals(lang)) {
                locale = new Locale(lang);
                Locale.setDefault(locale);
                config.locale = locale;
                config.setLayoutDirection(locale);
                getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());
            }
/* method I use for changing language of app */
    public static void resetLang(int item, Context context) {
        String lang = "";
        switch (item) {
            case PERSIAN:
                lang = PERSIAN_LANGUAGE;
                break;
            case ENGLISH:
                lang = ENGLISH_LANGUAGE;
                break;
        }
        Log.e(TAG, "lang: " + lang);
        MyApplication.prefHelper.putLanguage(lang);
        //setNewLocale(lang, true);
        Locale myLocale = new Locale(lang);
        Resources res = context.getResources();
        DisplayMetrics dm = res.getDisplayMetrics();
        Configuration conf = res.getConfiguration();
        conf.locale = myLocale;
        conf.setLayoutDirection(myLocale);
        res.updateConfiguration(conf, dm);

        Intent i = new Intent(context, MainActivity.class);
        context.startActivity(i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK));
        System.exit(0);
    }
        }

在基本活动中，我重写了此方法来应用字体：

    public abstract class BaseActivity extends AppCompatActivity {

    @Override
    protected void attachBaseContext(Context newBase) {
        super.attachBaseContext(ViewPumpContextWrapper.wrap(newBase));
    }
}
