У меня есть Навигационный ящик, но я использую фрагмент внутри ящика.Я не могу получить как привязку данных, так и фрагмент, работающий вместе.С примером кода привязка данных не работает.Если я изменяю binding = ContentNewSessionBinding.inflate(getLayoutInflater())
на binding = DataBindingUtil.setContentView(this, R.layout.content_new_session_);
, я получаю сообщение об ошибке, что фрагмент не может быть найден в представлении.
