My app uses a MultiColumnListView (https://github.com/huewu/PinterestLikeAdapterView) and as its name says it helps creating multi column list views.

You need to clear older myList.clear() and then call adapter.notifyDataSetChanged()
myList.clear()
adapter.notifyDataSetChanged()
Update:
Change your code like:
public MiAdaptadorListaComercios(Context c,List myList){ this.contexto = c; this.myList = new ArrayList(); }
Also, do it like
myList.clear(); myList.addAll(originalList);
