the class DragLayer method animateView.

/**
     * This method animates a view at the end of a drag and drop animation.
     *
     * @param view The view to be animated. This view is drawn directly into DragLayer, and so
     *        doesn't need to be a child of DragLayer.
     * @param from The initial location of the view. Only the left and top parameters are used.
     * @param to The final location of the view. Only the left and top parameters are used. This
     *        location doesn't account for scaling, and so should be centered about the desired
     *        final location (including scaling).
     * @param finalAlpha The final alpha of the view, in case we want it to fade as it animates.
     * @param finalScale 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 alphaInterpolator The interpolator to use for the alpha of the view.
     * @param onCompleteRunnable Optional runnable to run on animation completion.
     * @param fadeOut Whether or not to fade out the view once the animation completes. If true,
     *        the runnable will execute after the view is faded out.
     * @param anchorView If not null, this represents the view which the animated view stays
     *        anchored to in case scrolling is currently taking place. Note: currently this is
     *        only used for the X dimension for the case of the workspace.
