Call the below function to update the language.
private void updateLanguage(String languageCode) //languageCode ex. 'en' for english { Context context = LocaleHelper.setLocale(MainActivity.this, languageCode); Log.v("langcode", languageCode); Resources resources = context.getResources(); } Create a class named LocaleHelper to do the things.
class LocaleHelper { private static final String SELECTED_LANGUAGE = "Locale.Helper.Selected.Language"; public static Context onAttach(Context context) { String lang = getPersistedData(context, Locale.getDefault().getLanguage()); return setLocale(context, lang); } public static Context onAttach(Context context, String defaultLanguage) { String lang = getPersistedData(context, defaultLanguage); return setLocale(context, lang); } public static String getLanguage(Context context) { return getPersistedData(context, Locale.getDefault().getLanguage()); } public static Context setLocale(Context context, String language) { persist(context, language); Log.v("abcdef", Locale.getDefault().getLanguage()); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) { Log.v("Updatinglocale","Nougat"); return updateResources(context, language); } return updateResourcesLegacy(context, language); } public 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(); } @TargetApi(Build.VERSION_CODES.N) private static Context updateResources(Context context, String language) { Locale locale = new Locale(language); Locale.setDefault(locale); Configuration configuration = context.getResources().getConfiguration(); configuration.setLocale(locale); return context.createConfigurationContext(configuration); } @SuppressWarnings("deprecation") private static Context updateResourcesLegacy(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()); return context; } }
