View holder does not contain anything when it created, RecyclerView binds data to it.

ViewHolder Object is used to define each individual element in the list.

It itself a View so, it is added to the layout file as any other UI element is added.

RecyclerView is a ViewGroup that contains Views corresponding to your data.

RecyclerView was introduced in Material Design in Android 5.0(API level 21.0). In RecyclerView we supply data and define how each item looks, and the RecyclerView library dynamically creates the content when it is needed.

RecyclerView is used for providing a limited window to a large data set, which means it is used to display a large amount of data that can be scrolled very efficiently by maintaining a limited number of Views. RecyclerView is more flexible and advanced version of ListView and GridView.
