onBindViewHolder

Here we need to retrieve the article according to the position that we received, and load the text of the views accordingly:

override fun onBindViewHolder(holder: ViewHolder, position: Int) {    val article = articles[position]    holder.feed.text = article.feed    holder.title.text = article.title    holder.summary.text = article.summary}

This function will be called initially to display the first group of articles, and later will be called when the user scrolls to replace the content of the articles.
