About

A short description of RecyclerView.

Components

In order to use RecyclerView you need to setup following pieces:

• item: our data
• adapter: converts data/item to RecyclerView's format. Check also code comment.
• viewholders: pool of reuse views
• recyclerview: RecyclerView interacts with ViewHolder

Now we implement our logic

• create class Datasource: as the name suggests the data provider
• create data class ProgrammingLang: our entity

Transform model to android

Next we need a way to take the data from data source and format it to RecyclerView's format The transformation is done with Adapters.

Adapter is a design pattern that adapts the data into something that understands RecyclerView
