Try a different trick... instead of assigning the animation to the whole
list view (which works fine as a Layout Animation) try doing the animation
per view on each call of getView.
Since the dataset changes, getView will be called for each of the visible
views.. have each view animate itself out of view, replace the data with
the new data and then animate in. You'll probably have to use
onAnimationEndListener for doing the actual data replacement (on the
animation out)
