위의 소스코드처럼
데이터베이스를 이용한 커스텀 리스트뷰입니다. 그런데 데이터추가에 상관없이 항상 있어야하는 커스텀 리스트뷰를 배치해주고 싶습니다.
제 생각에는 리스트뷰에 뿌려줄 데이터들의 집합이 arSrc라는 변수라서 arSrc.add(new FavoriteFile(0,"이름","www.naver.com"));
이렇게 하면 되긴 되는데 기존에 있던 데이터는 다 지워지고 저 문장 하나만 뜹니다.
데이터에 상관없으니깐 adapter에 추가 시켜도 될꺼 같은데 adapter에는 추가하는 함수가 없더라구요
어떻게해야 추가를 안해도 항상 보이는 커스텀 리스트뷰를 만들 수 있을까요 ㅠ
