In your activiy_main.xml your recyclerview should look something like

<androidx.recyclerview.widget.RecyclerView
                            android:id="@+id/my_recyclerview"
                            android:layout_width="match_parent"
                            android:layout_height="wrap_content"
                            android:orientation="horizontal"
                            app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
                            tools:listitem="@layout/featured_product_item"/>

in your activity you can access it like so:

val recyclerview = findViewById<RecyclerView>(R.id.my_recyclerview)
