게시글읽기 공부하고 있는데요

해결 됬습니다. 신경써주셔서 감사합니다.

이부분이 문제 였네요.. ^^ ㅎㅎ

FBRef.user
    .child("Imdae")
    .child(uid)
    .addValueEventListener(postListener)

응용해서 만들어보고 있는데요

RVadapter

class ImdaeListRvAdapter (val imdaeDataList : MutableList<ImdaeListModel>) : BaseAdapter() {
    override fun getCount(): Int {
        return imdaeDataList.size
    }

    override fun getItem(position: Int): Any {
       return imdaeDataList[position]
    }

    override fun getItemId(position: Int): Long {
       return position.toLong()
    }

    override fun getView(position: Int, convertView: View?, parent: ViewGroup?): View {

        var view = convertView
        if (view == null) {
            view = LayoutInflater.from(parent?.context).inflate(R.layout.activity_imdae_list_adapter,parent, false)

        }

        val sename = view?.findViewById<TextView>(R.id.sename12)
        val sephone = view?.findViewById<TextView>(R.id.sephone12)
        val address = view?.findViewById<TextView>(R.id.imdaeaddress22)
        val kwanly = view?.findViewById<TextView>(R.id.imdaekwan11)
        val bojung = view?.findViewById<TextView>(R.id.imdaebo11)
        val worlse = view?.findViewById<TextView>(R.id.imdaeworl11)
        val mjbb = view?.findViewById<TextView>(R.id.imdaemyung11)

        sename!!.text = imdaeDataList[position].sename
        sephone!!.text = imdaeDataList[position].sephone
        address!!.text = imdaeDataList[position].address
        kwanly!!.text = imdaeDataList[position].kwanry
        bojung!!.text = imdaeDataList[position].bojung
        worlse!!.text = imdaeDataList[position].worldse
        mjbb!!.text = imdaeDataList[position].mjbb

        return view!!
    }

}

ListActivity

        binding.imdaeListView.adapter = imdaeListAdapter

        //임대 리스트
        getImdaeListData()



    }

    private fun getImdaeListData(){

        val user = database.getReference("userInfo")


    }

}

스크린샷

열심히 살펴봤는데 원인을 알수가 없네요...ㅠ.ㅠ

코드와 스크린샷으로 좀 더 상황을 자세히 설명해주시겠어요?
