Interfaces

ContextMenu Extension of Menu for context menus providing functionality to modify the header of the context menu. 
ContextMenu.ContextMenuInfo Additional information regarding the creation of the context menu. 
GestureDetector.OnDoubleTapListener The listener that is used to notify when a double-tap or a confirmed single-tap occur. 
GestureDetector.OnGestureListener The listener that is used to notify when gestures occur. 
KeyEvent.Callback  
LayoutInflater.Factory  
LayoutInflater.Filter Hook to allow clients of the LayoutInflater to restrict the set of Views that are allowed to be inflated. 
Menu Interface for managing the items in a menu. 
MenuItem Interface for direct access to a previously created menu item. 
MenuItem.OnMenuItemClickListener Interface definition for a callback to be invoked when a menu item is clicked. 
SubMenu Subclass of Menu for sub menus. 
SurfaceHolder Abstract interface to someone holding a display surface. 
SurfaceHolder.Callback A client may implement this interface to receive information about changes to the surface. 
View.OnClickListener Interface definition for a callback to be invoked when a view is clicked. 
View.OnCreateContextMenuListener Interface definition for a callback to be invoked when the context menu for this view is being built. 
View.OnFocusChangeListener Interface definition for a callback to be invoked when the focus state of a view changed. 
View.OnKeyListener Interface definition for a callback to be invoked when a key event is dispatched to this view. 
View.OnLongClickListener Interface definition for a callback to be invoked when a view has been clicked and held. 
View.OnTouchListener Interface definition for a callback to be invoked when a touch event is dispatched to this view. 
ViewGroup.OnHierarchyChangeListener Interface definition for a callback to be invoked when the hierarchy within this view changed. 
ViewManager Interface to let you add and remove child views to an Activity. 
ViewParent Defines the responsibilities for a class that will be a parent of a View. 
ViewStub.OnInflateListener Listener used to receive a notification after a ViewStub has successfully inflated its layout resource. 
ViewTreeObserver.OnGlobalFocusChangeListener Interface definition for a callback to be invoked when the focus state within the view tree changes. 
ViewTreeObserver.OnGlobalLayoutListener Interface definition for a callback to be invoked when the global layout state or the visibility of views within the view tree changes. 
ViewTreeObserver.OnPreDrawListener Interface definition for a callback to be invoked when the view tree is about to be drawn. 
ViewTreeObserver.OnScrollChangedListener Interface definition for a callback to be invoked when something in the view tree has been scrolled.

Window.Callback API from a Window back to its caller. 
WindowManager The interface that apps use to talk to the window manager. 

Classes

AbsSavedState A Parcelable implementation that should be used by inheritance hierarchies to ensure the state of all classes along the chain is saved. 
ContextThemeWrapper A ContextWrapper that allows you to modify the theme from what is in the wrapped context. 
Display  
FocusFinder The algorithm used for finding the next focusable view in a given direction from a view that currently has focus. 
GestureDetector Detects various gestures and events using the supplied MotionEvents. 
GestureDetector.SimpleOnGestureListener A convenience class to extend when you only want to listen for a subset of all the gestures. 
Gravity Standard constants and tools for placing an object within a potentially larger container. 
HapticFeedbackConstants Constants to be used to perform haptic feedback effects via performHapticFeedback(int)  
KeyCharacterMap  
KeyCharacterMap.KeyData  
KeyEvent Contains constants for key events. 
KeyEvent.DispatcherState Use with dispatch(Callback, DispatcherState, Object) for more advanced key dispatching, such as long presses. 
LayoutInflater This class is used to instantiate layout XML file into its corresponding View objects. 
MenuInflater This class is used to instantiate menu XML files into Menu objects. 
MotionEvent Object used to report movement (mouse, pen, finger, trackball) events. 
OrientationEventListener Helper class for receiving notifications from the SensorManager when the orientation of the device has changed. 
OrientationListener This class is deprecated. use OrientationEventListener instead. This class internally uses the OrientationEventListener.  
SoundEffectConstants Constants to be used to play sound effects via playSoundEffect(int)  
Surface Handle on to a raw buffer that is being managed by the screen compositor. 
SurfaceView Provides a dedicated drawing surface embedded inside of a view hierarchy. 
TouchDelegate Helper class to handle situations where you want a view to have a larger touch area than its actual view bounds. 
VelocityTracker Helper for tracking the velocity of touch events, for implementing flinging and other such gestures. 
View

This class represents the basic building block for user interface components. 

View.BaseSavedState Base class for derived classes that want to save and restore their own state in onSaveInstanceState()
View.MeasureSpec A MeasureSpec encapsulates the layout requirements passed from parent to child. 
ViewConfiguration Contains methods to standard constants used in the UI for timeouts, sizes, and distances. 
ViewDebug Various debugging/tracing tools related to View and the view hierarchy. 
ViewGroup

A ViewGroup is a special view that can contain other views (called children.) The view group is the base class for layouts and views containers. 

ViewGroup.LayoutParams LayoutParams are used by views to tell their parents how they want to be laid out. 
ViewGroup.MarginLayoutParams Per-child layout information for layouts that support margins. 
ViewStub A ViewStub is an invisible, zero-sized View that can be used to lazily inflate layout resources at runtime. 
ViewTreeObserver A view tree observer is used to register listeners that can be notified of global changes in the view tree. 
Window Abstract base class for a top-level window look and behavior policy. 
WindowManager.LayoutParams  

Enums

ViewDebug.HierarchyTraceType Defines the type of hierarhcy trace to output to the hierarchy traces file. 
ViewDebug.RecyclerTraceType Defines the type of recycler trace to output to the recycler traces file. 

Exceptions

InflateException This exception is thrown by an inflater on error conditions. 
Surface.OutOfResourcesException Exception thrown when a surface couldn't be created or resized  
SurfaceHolder.BadSurfaceTypeException Exception that is thrown from lockCanvas() when called on a Surface whose is SURFACE_TYPE_PUSH_BUFFERS. 
WindowManager.BadTokenException Exception that is thrown when trying to add view whose WindowManager.LayoutParams token is invalid.
