Problem in some views in items row of recyclerview "not showing like design preview"

Issue

I trying to practice some android lessons that contains recyclerview topic, currently I succeed to implement all api and response but there's one problem with my item_article_preview.xml.

The title and description of news doesn't shows in emulator like it's in design preview

After running the app

here's my xml row

my adapter class

private const val TAG = "NewsAdapter"
class NewsAdapter : RecyclerView.Adapter<NewsAdapter.ArticleViewHolder>() {


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

        val binding = ItemRowBinding.inflate(LayoutInflater.from(parent.context))
        return ArticleViewHolder(binding)

    }

    override fun onBindViewHolder(holder: ArticleViewHolder, position: Int) {
        val article = differ.currentList[position]
//        holder.bind(article)

        holder.binding.apply {
            Glide.with(this.root).load(article.urlToImage).into(ivArticleImage)
            tvSource.text = article.source.name
            tvTitle.text = article.title
            tvDescription.text = article.description
            tvPublishedAt.text = article.publishedAt

           [email protected] {
               onItemClickListener?.let {
                        it(article)
                    }
           }
        }


    }

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

    inner class ArticleViewHolder( val binding: ItemRowBinding) :
        RecyclerView.ViewHolder(binding.root) {

    private var onItemClickListener: ((Article) -> Unit)? = null


    private fun setOnItemClickListener(listener: (Article) -> Unit) {
        onItemClickListener = listener
    }

    private val diffCallBack = object : DiffUtil.ItemCallback<Article>() {

        override fun areItemsTheSame(oldItem: Article, newItem: Article): Boolean {
            return oldItem.id == newItem.id
        }

        override fun areContentsTheSame(oldItem: Article, newItem: Article): Boolean {
            return oldItem == newItem
        }

    }

    val differ = AsyncListDiffer(this, diffCallBack)
}

Solution

I found the problem causes this spilled of screen, here in this line

val binding = ItemRowBinding.inflate(LayoutInflater.from(parent.context))

you just inflated the inflater of a parent but there are two parameters is missing,

the viewGroup which it "parent and attachToRoot = false

edit your onCreateViewHolder like this

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ArticleViewHolder {
        val inflater = LayoutInflater.from(parent.context)
        val binding = ItemRowBinding.inflate(inflater,parent,false)
        return ArticleViewHolder(binding)

    }
