In simple words
ViewHolder => it conatins view like textView imageView ext.. if you have some data you can set that data in that view.
Adapter => he is links your data to the view. In adapter class you can override 2 important method
1. onCreatViewHolder => this method creats a list item view for storing yours data.
2. onBindViewHolder => this method put your data (Ex => images, text ) to the View.
That's what you made.
LayoutManager => The layout manager's job is how your View and data will appear in the layout.
