 *        final location (including scaling).
 * @param finalAlpha The final alpha of the view, in case we want it to fade as it animates.
 * @param finalScaleX The final scale of the view. The view is scaled about its center.
 * @param finalScaleY The final scale of the view. The view is scaled about its center.
 * @param duration The duration of the animation.
 * @param motionInterpolator The interpolator to use for the location of the view.
 * @param onCompleteRunnable Optional runnable to run on animation completion.
 * @param animationEndStyle Whether or not to fade out the view once the animation completes.
