когда я пытаюсь добавить onClickListener к просмотру карты, он не работает.
Я также пытался применить android:clickable="true"
ко всем картам, но безрезультатно. Он не показывает никаких ошибок и работает нормально, но прослушиватель onclick не работает. Может кто-нибудь сказать мне, если я сделал какую-либо ошибку. Это правильный путь или любой другой путь.
