Changing locale: Force activity to reload resources?

Question

So I have a language setting in my application. When the language is switched, I would like all the textviews etc to change language immediately. Currently I just change the

Answer 1

Assuming you're changing the language through something like

private void updateLocale(@NonNull final Context context,
                          @NonNull final Locale newLocale) {
    final Resources resources = context.getResources();
    final DisplayMetrics displayMetrics = resources.getDisplayMetrics();
    final Configuration configuration = resources.getConfiguration();
    configuration.locale = newLocale;
    resources.updateConfiguration(configuration, displayMetrics);
    Locale.setDefault(newLocale);
}

You'll need to call Activity.recreate() in all currently open activities, which is what would happen if the user changed the system language while you were not subscribing to android:configChanges="locale".
