위와 같이 구현을 하고싶어서ExpandableListView 내에 ScrollView 를 삽입하려고 합니다.
그냥 쓸수는 없고 커스터마이징이 필요한것 같아서 http://yoo454.tistory.com/entry/ExpandableListView-%EC%98%88%EC%A0%9C-%EC%8A%A4%ED%84%B0%EB%94%94 의 예제를 활용해 구현하려고 했습니다.
하지만 아래와같이 ExpandableListView 내의 리스트가 스크롤을 갖지 않더라구요..
이렇게 ExpandableListView 하위의 리스트가 스크롤을 갖지 않았습니다.
이를 해결할 방법이 없을까요??
아니면 다른방법의 코딩으로 구현하려면 어떤 방식이 좋을까요?
이하는 제가 구현한 코드입니다.
