What is the difference between a layout and a container in Android?

Question

In android studio, in design section, Layouts and Containers are categorized separately.

What is the fundamental difference between them?

Answer 1

I would define the differences as follows:

• Layouts are general-purpose ViewGroups dealing directly with graphical views. They have no requirements on what kind of children they can manage.
• Containers fulfill more specific tasks, that's why they have additional requirements on how many and which kind of children they can accept. Because of that most containers require writing Adapter classes in order to express those requirements.
