the class DynamicListView method handleCellSwitch.

     * determined and the data set is changed. Upon posting a notification of the
     * data set change, a layout is invoked to place the cells in the right place.
     * Using a ViewTreeObserver and a corresponding OnPreDrawListener, we can
     * offset the cell being swapped to where it previously was and then animate it to
     * its new position.
