Android > Viewholder/Adapter/layout manager

Question

Hi,
I'm beginner with Android Studio and I keep reading stuff about recyclerview, viewholder, adapter, layout manager but I cannot get what are viewholder, adapter and layout manager.
For now I only successed to understand how to add a text and edit it using Java xD
Tehn I don't get the workflowCan anyone can explain what they are with simple words ? Maybe compare it with daily life things ?

Answer 1

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.
