Le problème, dans ce cas prévis vient du fait que la méthode getSpanSizeForPosition(int) est appelé avec une position à -1. Comme la condition if (position < wrappers.size()) est remplie, l'application crash sur la ligne suivante :
return wrappers.get(position).getSpanSize();
Il convient donc de vérifier si, en plus, la position est bien supérieure ou égale à 0.
