        val inflater = LayoutInflater.from(parent.context)

        val binding = ListItemBinding.inflate(inflater)


        return MovieViewHolder(binding)

    }

    override fun getItemCount(): Int {
        return moviesList.size

    override fun onBindViewHolder(holder: MovieViewHolder, position: Int) {
        val movie = moviesList.get(position)

    class MovieViewHolder(val binding: ListItemBinding) : RecyclerView.ViewHolder(binding.root) {
        fun setMovieData(movie: MovieItem) {
            binding.curMovie = movie
        }
    }

    fun setMovieList(moviesList : List<MovieItem>){
        this.moviesList = moviesList
        notifyDataSetChanged()
    }

Most likely, the pakage name begins with a capital letter https://stackoverflow.com/a/54752522/11738109 or in list_item.xml use the full class path instead of a brief MovieItem

no capital letter in my package. i can access to my Repository on my type, but not to MovieItem. i've uploaded package screenshot – Bruse Feb 12 '20 at 15:06
You already tried to do like this type="com.example.myapplication.model.MovieItem"? And check for "package com.example.myapplication.model" above import in MovieItem file. – Evgeny Feb 12 '20 at 15:24
I've tried this already, i get cannot resolved symbol for MovieItem. already tried clean/invalidate etc. – Bruse Feb 12 '20 at 15:26
