Проблема с флажком. Когда пользователь нажимает на дочернее устройство, приложение должно показывать тост-сообщение, на которое нажал дочерний элемент. Он отлично работает, если я нажимаю на textview для ребенка, но когда я нажимаю на флажок, ничего не heppend. Также, когда я нажимаю на дочерний элемент, я хочу, чтобы мой флажок изменился. Вы видите то, чего я не вижу. Вот мой код основной деятельностиCheckBox у ребенка exapndablelistview (android)

Если я сфокусируюсь на моем флажке, он тоже не работает. У кого-то есть идея
