使用 AutocompleteTextView 和 onclicklistener 自定义 ArrayAdapter

嘿伙计们！我已经编写了一个 AutocompleteTextView 并且效果很好。现在我需要在自动完成的下拉视图上使用侦听器。我已经根据需要实现了自定义 ArrayAdapter，但现在当我使用侦听器时，我得到了一个执行 (IndexOutOfBoundExecption)。

autoCompleteTextView.setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView<?> listView, View view, int position, long id) {
                Intervento intervento = (Intervento) listView.getItemAtPosition(position);
                Integer idIntervento = intervento.getIdintervento();
                //autoCompleteTextView.setText(intervento);
            }
        });

listView 包含一个空的 arrayList ，它应该有服务器响应。

这是 arrayAdapter 自定义代码

public class AutoCompleteCustomAdapter extends ArrayAdapter<Intervento>  implements Filterable {

    static class ViewHolder{
         private TextView  textName;
    }

    private ArrayList<Intervento> arrayListIntervento;
    private int              layout;


    public ArrayList<Intervento> getArrayListIntervento() {
        return arrayListIntervento;
    }

    public void setArrayListIntervento(ArrayList<Intervento> arrayListIntervento) {
        this.arrayListIntervento = arrayListIntervento;
    }

    @Override
      public int getCount() {
        return arrayListIntervento.size();
      }

    @Override
    public Intervento getItem(int index) {
        return arrayListIntervento.get(index);
    }


     @Override
        public Filter getFilter() {
         Filter myFilter = new Filter() {
                @SuppressWarnings("unchecked")
                @Override
                protected void publishResults(CharSequence contraint, FilterResults results) {
                    if(results != null && results.count > 0) {
                        arrayListIntervento = (ArrayList<Intervento>)results.values;
                        setArrayListIntervento(arrayListIntervento);
                        notifyDataSetChanged();
                    }
                    else {
                        notifyDataSetInvalidated();
                    }
                }

                @Override
                protected FilterResults performFiltering(CharSequence arg0) {
                    FilterResults filterResults = new FilterResults();
                    if(arg0 != null) {
                        try {
                            arrayListIntervento = new InterventoController().execute("http://192.168.1.162:8080/Clinigo/InterventoHasSinonimoName/{interventohassinonimo_interventoNomeIntervento}/1/interventos", arg0.toString()).get();
                        }
                        catch(Exception e) {
                            e.printStackTrace();
                        }
                        // Now assign the values and count to the FilterResults object
                        filterResults.values = arrayListIntervento;
                        filterResults.count = arrayListIntervento.size();
                    }
                    return filterResults;
                }
            };
            return myFilter;
     }




    @Override
    public View getView(int position, View contentView, ViewGroup viewGroup) {

        View       view = null;
        ViewHolder viewHolder = null;

        if(contentView==null){
            LayoutInflater inflater =  (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            view = inflater.inflate(R.layout.suggest_list, viewGroup, false);

            if (view != null) {
                viewHolder = new ViewHolder();
                viewHolder.textName = (TextView) view.findViewById(R.id.nomeIntervento);
                view.setTag(viewHolder);
                Intervento intervento = arrayListIntervento.get(position);
                if(intervento!=null){
                    viewHolder.textName.setText(intervento.getNome());
                }
            }
        }else {
            view = contentView;
            viewHolder = (ViewHolder) contentView.getTag();
        }

        if (viewHolder != null) {
            Intervento intervento = arrayListIntervento.get(position);
            if(intervento!=null){
                viewHolder.textName.setText(intervento.getNome());
            }
        }

        return view;

    }

    public AutoCompleteCustomAdapter(Context context, int textViewResourceId) {
        super(context, textViewResourceId);

        this.arrayListIntervento= new ArrayList<Intervento>();
        this.layout=textViewResourceId;
    }


}

有什么建议么？
