Animation.RELATIVE_TO_PARENT.pivotXValue
- The X coordinate of the point about which the object
is being rotated, specified as an absolute number where 0 is the
left edge. This value can either be an absolute number if
pivotXType is ABSOLUTE, or a percentage (where 1.0 is 100%)

Animation.ABSOLUTE, Animation.RELATIVE_TO_SELF, or
Animation.RELATIVE_TO_PARENT.pivotYValue
- The Y coordinate of the point about which the object
is being rotated, specified as an absolute number where 0 is the

interpolatedTime
- The value of the normalized time (0.0 to 1.0)
after it has been run through the interpolation function.t
- The Transformation object to fill in with the current
transforms.public void initialize(int width, int height, int parentWidth, int parentHeight)
Animation
Objects that interpret Animations should call this method when
the sizes of the object being animated and its parent are known, and
before calling Animation.getTransformation(long, android.view.animation.Transformation)
.
