Provides classes that handle tweened animations.
Android provides two mechanisms
that you can use to create simple animations: tweened
animation, in which you tell Android to perform a series of simple
transformations (position, size, rotation, and so on) to the content of a
View; and frame-by-frame animation, which loads a series of Drawable resources
one after the other. Both animation types can be used in any View object
to provide simple rotating timers, activity icons, and other useful UI elements.
Tweened animation is handled by this package (android.view.animation); frame-by-frame animation is
handled by the AnimationDrawable class.
For more information on creating tweened or frame-by-frame animations, read the discussion in the 2D Graphics Dev Guide.
| Animation.AnimationListener | An animation listener receives notifications from an animation. |
| Interpolator | An interpolator defines the rate of change of an animation. |
| 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. |
| AlphaAnimation | An animation that controls the alpha level of an object. |
| Animation | Abstraction for an Animation that can be applied to Views, Surfaces, or other objects. |
| Animation.Description | Utility class to parse a string description of a size. |
| AnimationSet | Represents a group of Animations that should be played together. |
| AnimationUtils | Defines common utilities for working with animations. |
| 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. |
| 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. |
| GridLayoutAnimationController | A layout animation controller is used to animated a grid layout's children. |
| GridLayoutAnimationController.AnimationParameters | The set of parameters that has to be attached to each view contained in the view group animated by the grid layout animation controller. |
| LayoutAnimationController | A layout animation controller is used to animated a layout's, or a view group's, children. |
| LayoutAnimationController.AnimationParameters | The set of parameters that has to be attached to each view contained in the view group animated by the layout animation controller. |
| LinearInterpolator | An interpolator where the rate of change is constant |
| OvershootInterpolator | An interpolator where the change flings forward and overshoots the last value then comes back. |
| RotateAnimation | An animation that controls the rotation of an object. |
| ScaleAnimation | An animation that controls the scale of an object. |
| Transformation | Defines the transformation to be applied at one point in time of an Animation. |
| TranslateAnimation | An animation that controls the position of an object. |
