Views and layout manager

Views are user interface widgets, e.g. buttons or text fields. Views have attributes which can be used to configure their appearance and behavior.

A ViewGroup is responsible for arranging other views. It is also known as layout manager. The base class for these layout managers is the android.view.ViewGroup class which extends theandroid.view.View class which is the base class for views.

Layout managers can be nestled to create complex layouts.
