Connecting the adapter to the activity

Now we have an adapter that can map a List<Article> into views. We just need to use this adapter in conjunction with the RecyclerView that we added to the main activity.

For this, we will need some variables in our MainActivity class:

class MainActivity : AppCompatActivity() {    ...    private lateinit var articles: RecyclerView    private lateinit var viewAdapter: ArticleAdapter    private lateinit var viewManager: RecyclerView.LayoutManager    ...}

We will instantiate all of them inside the onCreate() function:

override fun onCreate(savedInstanceState: Bundle?) {    super.onCreate(savedInstanceState)    setContentView(R.layout.activity_main)    viewManager = LinearLayoutManager(this)    viewAdapter = ArticleAdapter() articles ...
