ViewGroup is a subclass of the Android View class(parent of all Android graphical widgets) which can contain child views.

ViewGroup is the base class for all Android layouts and views containers. This class is designed to be extended so the user can implement his own layout(which arranges the children following the desired logic, one not covered by the standards layouts) or a new view container.
