Yes for some reason you need to use a listener:

defaultLocale = $defaultLocale;
  }

  public function onKernelRequest(GetResponseEvent $event)
  {
  $request = $event->getRequest();
  if (!$request->hasPreviousSession()) {
      return;
  }

  if ($locale = $request->attributes->get('_locale')) {
      $request->getSession()->set('_locale', $locale);
  } else {
      $request->setLocale($request->getSession()->get('_locale', $this->defaultLocale));
  }
  }

  static public function getSubscribedEvents()
  {
  return array(
      // must be registered before the default Locale listener
      KernelEvents::REQUEST => array(array('onKernelRequest', 17)),
  );
  }
}
?>

Register your listener in your service.xml:

    %locale%
    

An example how to implement the language switcher in your twig template:

{% for locale in ['en', 'fr','zh'] %}
    

      
        {% if locale == 'en' %}
        
        {% elseif locale == 'fr' %}
        
        {% endif %}
