Пожалуйста, мне нужна помощь, я схожу с ума от Android. Здесь у вас есть код mi и падение logcat, я надеюсь, вы можете показать мне путь.
Для лучшего понимания, что я ищу, это; Внутри действия «concejos» есть прокручиваемые вкладки, каждая вкладка представляет собой макет, похожий на фрагмент, внутри этих макетов есть кнопки, которые откроют фрагмент диалога с изображением, текстом и кнопкой закрытия.
