RecyclerView is possibly most used View in Android development for showing list of items. There was something called ListView the use of which is now outdated. It is not deprecated but RecyclerView does much better task of managing list of thousands of items. It is because of the View Holder pattern.
RecyclerView relies on this functionality to correctly position the view as the list scrolls, and to do interesting things like animate views when items are added or removed in the Adapter. If RecyclerView does need to access the views stored in the ViewHolder, it can do so using the view holder’s itemView property. RecyclerView uses itemView.
Why do we have RecyclerView? Because we also had ListView. We have the Item Animator that handles the animations because animations are also first class in RecyclerView, and we have the adapter that takes If the user is scrolling or something else happens, the item might be detached.
