We are going to jump directly to code first creating Adapter class which will responsible for inflating ReclerViews  with list_items view

create package called adapters and inside it create CardAdapter class which extends Recycler.Adapter copy the following code in your CardAdapter class.

 

The above CardAdapter class has three main methods onCreateViewHolder which  inflates the layout to main parent of the RecyclerView.

onBindViewHolder takes each views of the all_news.xml and set the values from AllNewsData class which contains setters and getters methods for each individual views.

Another important point to note is the use of Glide library to load images to the view.
