AutoCompleteTextView force to show all items

Question

There is a moment in my app, that I need to force to show all items in the suggestion list, no matter what the user has typed. How can I do that?

Basically, after 5-6 hours of experimentation to understand how the damn filter works, I wrote my own adapter which does exactly what I want:

    public class burtuAdapteris extends ArrayAdapter implements Filterable {

       ArrayList _items = new ArrayList();
       ArrayList orig = new ArrayList();

       public burtuAdapteris(Context context, int resource, ArrayList items) {
           super(context, resource, items);    

           for (int i = 0; i < items.size(); i++) {
                orig.add(items.get(i));
            }
       }

       @Override
       public int getCount() {
           if (_items != null)
               return _items.size();
           else
               return 0;
       }

       @Override
       public String getItem(int arg0) {
           return _items.get(arg0);
       }


      @Override

      public Filter getFilter() {
          Filter filter = new Filter() {
              @Override
              protected FilterResults performFiltering(CharSequence constraint) {

                  if(constraint != null)
                      Log.d("Constraints", constraint.toString());
                  FilterResults oReturn = new FilterResults();

                /*  if (orig == null){
                    for (int i = 0; i < items.size(); i++) {
                        orig.add(items.get(i));
                    }
                  }*/
                  String temp;  
                  int counters = 0;
                  if (constraint != null){

                      _items.clear();
                      if (orig != null && orig.size() > 0) {
                          for(int i=0; i 0) {
                        notifyDataSetChanged();
                        }
                        else {
                            notifyDataSetInvalidated();
                        }

              }

            };

          return filter;

      }


 }

And it's simple to use, just replace original adapter with this:

final burtuAdapteris fAdapter = new burtuAdapteris(this, android.R.layout.simple_dropdown_item_1line, liste);

In my case liste is: ArrayList liste = new ArrayList();
