Я пытаюсь определить событие нажатия кнопки вниз для класса карты. Код для метода обновления класса карты приведен ниже. Всякий раз, когда я нажимаю на карту, сообщение не появляется. Я предоставил полный код для класса карты ниже. Моя задача - добавить функциональность в класс Card, чтобы он мог обнаружить событие касания, происходящее на карте.
