android - 未连接适配器；跳过datalist中的布局问题

Question

我得到了错误：

recyclerview 没有附加适配器；跳过布局

而且recyvlerview中的数据根本没有显示。我正在使用 firebase 并想从子“fasilitas”中获取数据，但出现了这样的错误。我应该怎么办？

HotelDetailActivity.kt

class HotelDetailActivity : AppCompatActivity() {

    private lateinit var mDatabase : DatabaseReference
    private var dataList = ArrayList<FasilitasModel>()

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_hotel_detail)

        val data = intent.getParcelableExtra<Hotel>("data")

        mDatabase = FirebaseDatabase.getInstance().getReference("Hotel")
            .child(data!!.namaHotel.toString())
            .child("fasilitas")

        tv_namaHotel.text = data!!.namaHotel
        tv_biaya.text = data!!.biaya
        tv_deskripsi.text = data!!.deskripsi
        tv_lokasi.text = data!!.lokasi
        tv_rate2.text = data!!.rating

        Glide.with(this)
            .load(data.poster)
            .into(iv_poster)

        rv_fasilitas.layoutManager = LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false)
        getData()
    }

    private fun getData() {
        mDatabase.addValueEventListener(object: ValueEventListener{
            override fun onDataChange(snapshot: DataSnapshot) {
                dataList.clear()
                for(getdataSnapshot in snapshot.children){
                    var Hotel = getdataSnapshot.getValue(FasilitasModel::class.java)
                    dataList.add(Hotel!!)
                }
                rv_fasilitas.adapter = FasilitasAdapter(dataList){

                }
            }

            override fun onCancelled(error: DatabaseError) {
                Toast.makeText(this@HotelDetailActivity, ""+error.message, Toast.LENGTH_LONG).show()
            }

        })
    }

}

Fasilitas适配器

class FasilitasAdapter(
    private var data: List<FasilitasModel>,
    private val listener: (FasilitasModel) -> Unit)
    : RecyclerView.Adapter<FasilitasAdapter.LeagueViewHolder>() {

    lateinit var contextAdapter: Context

    override fun onCreateViewHolder(
        parent: ViewGroup,
        viewType: Int
    ): LeagueViewHolder {

        val layoutInflater = LayoutInflater.from(parent.context)
        contextAdapter = parent.context
        val inflatedView: View = layoutInflater.inflate(R.layout.row_item_fasilitas, parent, false)

        return LeagueViewHolder(inflatedView)
    }

    override fun onBindViewHolder(holder: LeagueViewHolder, position: Int) {
        holder.bindItem(data[position], listener, contextAdapter, position)
    }

    override fun getItemCount(): Int = data.size

    class LeagueViewHolder(view: View) : RecyclerView.ViewHolder(view) {
        private val tvNamaFasilitas: TextView = view.findViewById(R.id.tv_fasilitas)
        private val ivFasilitas: ImageView = view.findViewById(R.id.iv_ic_fasilitas)

        fun bindItem(data: FasilitasModel, listener: (FasilitasModel) -> Unit, context: Context, position: Int) {

            tvNamaFasilitas.text = data.nama

            Glide.with(context)
                .load(data.url)
                .apply(RequestOptions.circleCropTransform())
                .into(ivFasilitas)

            itemView.setOnClickListener {
                listener(data)
            }
        }
    }
}

Fasilitas模型

import android.os.Parcelable
import kotlinx.android.parcel.Parcelize

@Parcelize
data class FasilitasModel (
    var nama: String ?="",
    var url: String ?=""
): Parcelable

酒店模型

import android.os.Parcelable
import kotlinx.android.parcel.Parcelize

@Parcelize
data class Hotel (
    var biaya: String ?="",
    var deskripsi: String ?="",
    var lokasi: String ?="",
    var namaHotel: String ?="",
    var poster: String ?="",
    var rating: String ?="",
): Parcelable

Firebase 数据库

RecyclerView 不显示仅发生在“设施”而不是“酒店”上。我在代码中看不到任何红色警告，只有布局未显示，并且 logcat 中出现“未连接适配器；正在跳过”警告。谢谢你 ：）
