인프런 커뮤니티 질문&답변

감사합니다.

오타 찾았어요

복붙하다가 수정을 빼먹은게 있었네요

for (dataModel in dataSnapshot.children) {
        val item = dataModel.getValue(CommentModel::class.java)
        Log.d("comment : " , item.toString())
        commentDataList.add(item!!)
    }
    commentAdapter.notifyDataSetChanged()
}

이부분

Log.d("comment : " , item.toString()) 이거 넣고
댓글쓴후 로그창 열어서 comment 검색했습니다

로그창에 CommentModel(commentTitle=aa1
    , commentCreatedTime=2021.11.10 08:34:00)

이런식으로 쭉 나와요

commentTitle=aa1 이부분이 댓글 내용이고 뒷부분이 시간 뜨네요

댓글 내용과 시간 쭉 나오고 이외에는 안떠요

동영상 댓글 입력하기~댓글 수정하기 부분이요

에러는 안보이는듯 합니다.. 로그내용 없애고 댓글써도 로그창에 안뜨네요

파이어베이스 댓글창 맞죠??

오른쪽에 댓글이 안보이는데 왜 이런건가요?
