我正在Kotlin中构建一个简单的电影应用程序（练习面试的现场编码），从这个教程：Build a Movie App using Retrofit and MVVM Architecture with Kotlin。一切都发生在主活动onCreate中，我想移动功能以使用片段。我目前收到错误"E/RecyclerView：未连接适配器;正在跳过布局""。
我已经看过许多类似的职位没有成功。这里是我的代码下面。所有的日志调用正在发生，除非指出。我会更新问题，如果需要更多的信息。
适配器：

package com.example.interviewpracticemvvm.adapter

import android.content.ContentValues.TAG
import android.util.Log
import android.view.LayoutInflater
import android.view.ViewGroup
import androidx.recyclerview.widget.RecyclerView
import com.bumptech.glide.Glide
import com.example.interviewpracticemvvm.databinding.MovieLayoutBinding
import com.example.interviewpracticemvvm.model.Result

class MovieAdapter : RecyclerView.Adapter<MovieAdapter.ViewHolder>() {
    private var movieList = ArrayList<Result>()

    fun setMovieList(movieList: List<Result>) {
        this.movieList = movieList as ArrayList<Result>
        notifyDataSetChanged()
        Log.d(TAG, "setMovieList called in adapter")
    }

    class ViewHolder(val binding: MovieLayoutBinding) : RecyclerView.ViewHolder(binding.root) {}

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
        return ViewHolder(
            MovieLayoutBinding.inflate(
                LayoutInflater.from(
                    parent.context
                )
            )
        )
        Log.d(TAG, "onCreateViewHolder called") //Not being called

    }

    override fun onBindViewHolder(holder: ViewHolder, position: Int) {
        Glide.with(holder.itemView)
            .load("https://image.tmdb.org/t/p/w500" + movieList[position].poster_path)
            .into(holder.binding.movieImage)
        holder.binding.movieName.text = movieList[position].title
        Log.d(TAG, "onBindViewHolder called") // Not being called

    }

    override fun getItemCount(): Int {
        return movieList.size
    }
}

我在使用数据绑定和safeargs时遇到了一系列的错误。我还没有找到一个帖子指出一个明显的问题。这个错误看起来不够具体，它可能是由项目中的许多事情引起的。
