Add a Filter on an ArrayAdapter to AutoCompleteTextView (Android)

gistfile1.java

@Override
public Filter getFilter() {
  Filter myFilter = new Filter() {
    @Override
    protected FilterResults performFiltering(CharSequence constraint) {
      FilterResults filterResults = new FilterResults();
      if(constraint != null) {
        List<GenericProduct> filteredProducts = new ArrayList<GenericProduct>();
        for(GenericProduct currentGenericProduct : genericProductList){
          if(currentGenericProduct.getName().contains(constraint)){
            filteredProducts.add(currentGenericProduct);
          }
        }
        // Now assign the values and count to the FilterResults object
        filterResults.values = filteredProducts;
        filterResults.count = filteredProducts.size();
      }
      return filterResults;
    }

    @Override
    protected void publishResults(CharSequence contraint, FilterResults results) {
      if(results != null && results.count > 0) {
      notifyDataSetChanged();
      }
      else {
        notifyDataSetInvalidated();
      }
    }
  };
  return myFilter;
}
