RecyclerView does not handle item selection or states like a ListView does. Instead you have to handle this manually in your view holder.

The first thing you can do is declare your item view as clickable, in your `ViewHolder constructor :

public ViewHolder(View itemView) { super(itemView);

// Make this view clickable
itemView.setClickable(true);

// ...

}
