RotateAnimation

public class RotateAnimation
extends Animation

java.lang.Object
↳	android.view.animation.Animation
	↳	android.view.animation.RotateAnimation

An animation that controls the rotation of an object. This rotation takes place in the X-Y plane. You can specify the point to use for the center of the rotation, where (0,0) is the top left point. If not specified, (0,0) is the default rotation point.

Public methods

initialize

Added in API level 1

void initialize (int width, 
                int height, 
                int parentWidth, 
                int parentHeight)

Initialize this animation with the dimensions of the object being animated as well as the objects parents. (This is to support animation sizes being specified relative to these dimensions.)

Objects that interpret Animations should call this method when the sizes of the object being animated and its parent are known, and before calling getTransformation(long, Transformation).

Parameters
`width`	`int`: Width of the object being animated
`height`	`int`: Height of the object being animated
`parentWidth`	`int`: Width of the animated object's parent
`parentHeight`	`int`: Height of the animated object's parent

Protected methods

applyTransformation

Added in API level 1

void applyTransformation (float interpolatedTime, 
                Transformation t)

Helper for getTransformation. Subclasses should implement this to apply their transforms given an interpolation value. Implementations of this method should always replace the specified Transformation or document they are doing otherwise.

Parameters
`interpolatedTime`	`float`: The value of the normalized time (0.0 to 1.0) after it has been run through the interpolation function.
`t`	`Transformation`: The Transformation object to fill in with the current transforms.
