In Java, classes can be nested within one another in order to organize data and functionality in an orderly fashion. Anonymous inner classes are basically developer shorthand, allowing the developer to create, define, and use a custom object all in one go. Anonymous inner classes are frequently used in Android to define handlers for controls, define and launch new threads, and create and return custom objects in methods without cluttering code with unnecessary setup.

For a thorough discussion of nested and inner classes, including anonymous inner classes, see our tutorial called Learn Java for Android Development: Inner Classes
