AndroidSome new terms are introduced for similar programming terms, which will be described in the following sections:

Views

View is a basic UI class in the visual interface element and a commonly known control or widget ). All the UI controls and layout classes are inherited from the View.

ViewGroups

ViewGroup is an extension of View. It can accommodate multiple sub-views. By extending the ViewGroup class, you can create a composite control composed of correlated sub-views. The ViewGroup class can also be extended as the layout manager, such as LinearLayout, to help you build the UI.

Activities

Activity, which is described in detail in the previous chapter, represents a window or screen displayed to the user. Activity is the Form in Android. To display the UI, you only need to specify View or Layout for the Activity.

Android provides some general UI controls, widgets, and layout managers.
