notifyDataSetChanged not working

Question

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

Answer 1

You need to clear older myList.clear() and then call adapter.notifyDataSetChanged()

Update:

Change your code like:

public MiAdaptadorListaComercios(Context c,List<Comercio> myList){
this.contexto = c;
this.myList = new ArrayList<Comercio>();
}

Also, do it like

myList.clear();
myList.addAll(originalList);   

Answer 2

just change your myList and call adapter.notifyDataSetChanged() don't set a new adapter each time.

In the constructor of your custom adapter do call super that takes ArrayList as the argument.

call this:

public MiAdaptadorListaComercios(Context c,List<Comercio> myList){
    super(c,0,myList);
    this.contexto = c;
    this.myList = myList;
}

You can keep the adapter as it is the problem is in this line:

myList = filteredList;

instead of changing the reference you should change the list itself.

myList.clear();
myList.addAll(filteredList);

By doing this you will loose your original list to I would suggest keeping another list call ed originalList which will have the complete list and initialize myList in onCreate by:

myList=new ArrayList(originalList);

so every time you want to re-set just call:

myList.clear();
myList.addAll(originalList);    

and in

    for(Comercio co : originalList)
            {
                if(co.getName().contains(filer))
                {
                    filteredList.add(co);
                }
            }
