내베이스 어댑터 클래스에 변수를 설정 했으므로 관련 액티비티에서이 변수를 얻고 싶습니다. 나는 이것을하는 방법을 얻지 못하고있다.베이스 어댑터에서 변수 값을 액티비티로 전달
여기 내 코드입니다.

나는 관련 활동에 PRODID를 전달하려는.
참고 : 기본 어댑터가 활동
adapter = new TourDescAdapter(currentTour.getListOfDescriptions(), this);
setListAdapter(adapter);
어떻게 이렇게 말해 줄 수있는 모든 하나라고?
반환 변수 값을 사용하여 어댑터에 공용 메서드를 만들고 variable = adapter.methodName(); –
@tejas 나는 같은 문제가있어! 어떻게 baseadapter에서 값을 –
님께 전할 수 있을까요? 안녕하세요 priya, 지연된 응답에 대해 사과드립니다. 요즘 인터넷에 접속할 수 없었습니다. 시나리오가 정확히 무엇인지 말해 줄 수 있습니까? – tejas
