얘는 BoardListAdapter.kt 입니다

badge에 관하여 질문드립니다.

하나만 더 여쭈어 보겠습니다.
&nbsp;
1.최초에 글 작성 버튼을 누르면 time stamp를 저장한다.
&nbsp;
&nbsp;private var timestamp = System.currentTimeMillis()
binding.writeBtn.setOnClickListener {
&nbsp;
&nbsp;
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; val title = binding.titleArea.text.toString()
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; val contents = binding.contentsArea.text.toString()
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; val uid = FBAuth.getUid()
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; val time = FBAuth.getTime()
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; val key = FBRef.boardRef.push().key.toString()
&nbsp;
&nbsp;
&nbsp;
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; FBRef.boardRef
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; .child(key)
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; .setValue(BoardModel(title, contents, uid, time, timestamp.toString()))
}
data class BoardModel(
&nbsp;
&nbsp; &nbsp; val title: String="",
&nbsp; &nbsp; val content: String="",
&nbsp; &nbsp; val uid: String="",
&nbsp; &nbsp; val time: String="",
&nbsp; &nbsp; val timestamp:String =""
&nbsp;
&nbsp; &nbsp; )
&nbsp;
2. BoardListAdapter에서 연결한다.
&nbsp;
여기서 좀 애를 먹고 있는데
이유는
데이터를 가져오는 정확한 방법을 잘 모르겠습니다.
&nbsp;
private val database by lazy { FirebaseDatabase.getInstance() }
private val userRef = database.getReference("board")
val timestamps = userRef.child("timestamp").toString() < 이런식으로 가지고 오는게 맞나요?
&nbsp;
파이어베이스 안에 timestamp는 잘 들어간 상태입니다

&nbsp;
요런식으로요.
&nbsp;
&nbsp;

원인을 찾았네요! parent로 선언이 안되어있고 p2로 되어있네용
