Interfaces

Animator.AnimatorListener

An animation listener receives notifications from an animation. 

Animator.AnimatorPauseListener A pause listener receives notifications from an animation when the animation is paused or resumed
Animator.AnimatorUpdateListener Implementors of this interface can add themselves as update listeners to an ValueAnimator instance to receive callbacks on every animation frame, after the current frame's values have been calculated for that ValueAnimator
Interpolator An interpolator defines the rate of change of an animation. 
TimeAnimator.TimeListener Implementors of this interface can set themselves as update listeners to a TimeAnimator instance to receive callbacks on every animation frame to receive the total time since the animator started and the delta time since the last frame. 
TypeEvaluator<T> Interface for use with the ValueAnimator.setEvaluator(TypeEvaluator) function. 

Classes

AccelerateDecelerateInterpolator An interpolator where the rate of change starts and ends slowly but accelerates through the middle. 
AccelerateInterpolator An interpolator where the rate of change starts out slowly and and then accelerates. 
Animator This is the superclass for classes which provide basic support for animations which can be started, ended, and have AnimatorListeners added to them. 
AnimatorInflater This class is used to instantiate animator XML files into Animator objects. 
AnimatorListenerAdapter This adapter class provides empty implementations of the methods from Animator.AnimatorListener
AnimatorSet This class plays a set of Animator objects in the specified order. 
AnimatorSet.Builder The Builder object is a utility class to facilitate adding animations to a AnimatorSet along with the relationships between the various animations. 
AnimatorTestRule JUnit TestRule that can be used to run Animators without actually waiting for the duration of the animation. 
AnticipateInterpolator An interpolator where the change starts backward then flings forward. 
AnticipateOvershootInterpolator An interpolator where the change starts backward then flings forward and overshoots the target value and finally goes back to the final value. 
ArgbEvaluator This evaluator can be used to perform type interpolation between integer values that represent ARGB colors. 
BidirectionalTypeConverter<T, V> Abstract base class used convert type T to another type V and back again. 
BounceInterpolator An interpolator where the change bounces at the end. 
CycleInterpolator Repeats the animation for a specified number of cycles. 
DecelerateInterpolator An interpolator where the rate of change starts out quickly and and then decelerates. 
FloatArrayEvaluator This evaluator can be used to perform type interpolation between float[] values. 
FloatEvaluator This evaluator can be used to perform type interpolation between float values. 
FloatProperty<T> An implementation of Property to be used specifically with fields of type float
IntArrayEvaluator This evaluator can be used to perform type interpolation between int[] values. 
IntEvaluator This evaluator can be used to perform type interpolation between int values. 
IntProperty<T> An implementation of Property to be used specifically with fields of type int
Keyframe<T> This class holds a time/value pair for an animation. 
LinearInterpolator An interpolator where the rate of change is constant  
ObjectAnimator This subclass of ValueAnimator provides support for animating properties on target objects. 
OvershootInterpolator An interpolator where the change flings forward and overshoots the last value then comes back. 
PathInterpolator An interpolator that can traverse a Path that extends from Point (0, 0) to (1, 1)
PointFEvaluator This evaluator can be used to perform type interpolation between PointF values. 
PropertyValuesHolder This class holds information about a property and the values that that property should take on during an animation. 
RectEvaluator This evaluator can be used to perform type interpolation between Rect values. 
TimeAnimator This class provides a simple callback mechanism to listeners that is synchronized with all other animators in the system. 
TypeConverter<T, V> Abstract base class used convert type T to another type V. 
ValueAnimator This class provides a simple timing engine for running animations which calculate animated values and set them on target objects.
