-Whatever we see in any android app is considered as a VIEW. Generally, an android app is a collection of more than one views i.e. you get text, images, buttons, etc. on any application. For example, the logging page of facebook app consists of various views such as facebook logo(ImageView), text field to enter username and password(EditText), login button(Buttons), create new account(Button), etc. These view combinedly make a great looking app like facebook. So here we will try to look onto some of these views.

 **Layout**   
-A layout defines the structure for a user interface in your app.   
-All elements in the layout are built using a hierarchy of View and ViewGroup objects. A View usually draws something the user can see and interact with. Whereas a ViewGroup is an invisible container that defines the layout structure for View and other ViewGroup objects, as shown in figure.(We will see more about ViewGroup)

-So, to make it very simple we can say that android uses certain type of technique called XML(Extensible Markup Language) to define all these type of Views and ViewGroups.Android provides a straightforward XML vocabulary that corresponds to the View classes and subclasses, such as those for widgets and layouts.    
-You can also use Android Studio's Layout Editor to build your XML layout using a drag-and-drop interface.
