북마크 탭에서 삭제기능을 추가하려고합니다

선생님 저가 그전 코드에서 부터 getBookmarkData()에서 bookmarkIdList.clear()넣으니깐 idlist 에선 잘 삭제가된걸 확인했는데...Bookmarklayout 에서 그전 idlist 값이 남아있어서? 삭제하면 그전 레이아웃 idlist 값의 레이아웃(이미지) 새롭게 드가는 idlist 값이 동시에 공존해있어 문의 드렸어용혹시나 싶어서 getCategoryData() 에서 bookmarkIdList.clear() 넣어도 그전 idlist (이미지)값 이 bookmarkFragment에 남아있더라구요...ㅠㅠ그래서 이걸 삭제할때마다 레이아웃을 새롭게 리셋 시켜야하나 싶어서 문의드렸어요
