Android LinearLayout Example

 

In Android application, an activity displays the user interface (UI).

An activity provides a screen with Views and ViewGroups.

A View represents a widget such as button, label, text field…

A ViewGroup is a container that can group other Views or other ViewGroups.

The LinearLayout is a ViewGroup providing a layout in which views are ordered in a single column (vertical orientation) or a single row (horizontal orientation).

In this example, we will see how to use the LinearLayout to arrange our views and define their layout properties.
