어쩌다 안드로이드를 잠깐 코딩해야하는 상황이 와서요..
어렵게 어렵게 짜집기하면서 만들어보고있는데..쉽지가않네요^^;;;
ExpandableListView를 만드는데.. Child 리스트뷰는 하나씩만 만들고
그곳에 이미지뷰와 텍스트뷰를 이용하여 마치 공지사항 게시판처럼 꾸미려 합니다.
가져온 예제는 String배열에 넣은 글자만 출력하는거라서, 제가 추가한 ImageView는
어떤식으로 추가를 해줘야할지 상당히 막막하네요...ㅎㅎ
다른부분에서 Socket 통신을 구현해서 URL을 받아오는 식으로 구현중인데
해당 Child ListView에서 URL로 이미지를 출력하는 메소드랑 방법좀 알수있을까요?
아래는 소스입니다...
