  <p>Kotlin code within the RecyclerViewAdapter,</p>
  
  <pre><code>class RecyclerViewAdapter(private val recyclerViewItems: ArrayList&lt;HearthstoneCardItemData&gt;, context: Context) :

          return RecyclerViewHolder(view)
      }
  }
  </code></pre>
  
  <p>Below is the xml layout.</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
                xmlns:card_view="http://schemas.android.com/apk/res-auto"

                android:orientation="vertical"&gt;
      &lt;android.support.v7.widget.CardView
              android:id="@+id/cardView"
              android:layout_width="match_parent"
              android:layout_height="150dp"

                      android:padding="5dp"/&gt;
          &lt;/RelativeLayout&gt;
  
      &lt;/android.support.v7.widget.CardView&gt;
  
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>I've also added the right dependencies within the gradle file (i think)</p>
  
  <pre><code>implementation 'androidx.appcompat:appcompat:1.1.0-alpha02'
  implementation 'androidx.recyclerview:recyclerview:1.1.0-alpha02'
  implementation 'androidx.cardview:cardview:1.0.0'
  </code></pre>
  
  <p>I've cleaned  re-build as well, still no change
  Any advice would be appreciated!</p>
