Introduction to Layout

In this tutorial we discuss about layouts.

A layout defines the visual structure for a user interface, such as the UI for an activity or app widget.
You can declare a layout in two ways:

Instantiate layout elements at runtime: Your application can create View and ViewGroup objects (and manipulate their properties) programmatically.
