What you want to do is have a flag that knows if the row is expanded or not. If it is, then run an animation that shrinks it, and vice versa.

public void onListItemClicked(int position)
{
    View v = listView.getView(position);
    if(expanded[position])
      v.startAnimation(shrinkAnimation);
    else
      v.startAnimation(growAnimation);  
    expanded[position] = !expanded[position];
}

Simple.

However if what you are doing is something similar to the screen shot you implemented, I would advise against doing this with a ListView. The views are each different enough to warrant just doing this manually with LinearLayouts. Only use the ListView if the number of rows is unknown or very large.
