세번째 코드에서 선생님과 다르게  BoardListLVAdapter 가 아닌 BoardListVAdapter으로 이름을 지었습니다

첫번째 이미지 파이어베이스 데이터입니다.

첫번째 코드 BoardModel.kr입니다.

두번째 코드 FBRef.kr입니다.

세번째 코드 TalkFragmant.kr입니다.

package com.example.sololife.board

data class BoardModel (
    val title : String = "",
    val content : String = "",
    val uid : String = "",
    val time : String = ""
)

package com.example.sololife.utils

import com.google.firebase.database.ktx.database
import com.google.firebase.ktx.Firebase

class FBRef {

    companion object {

        private val database = Firebase.database

        val category1 = database.getReference("contents")
        val category2 = database.getReference("contents2")
        val category3 = database.getReference("contents3")
        val category4 = database.getReference("contents4")
        val category5 = database.getReference("contents5")
        val category6 = database.getReference("contents6")
        val category7 = database.getReference("contents7")
        val category8 = database.getReference("contents8")

        val bookmarkRef = database.getReference("bookmark_list")
        val boardRef = database.getReference("board")

    }

}
