Problem with Searchview android

Good to the problem, first I have a Searchview in my actionbar . I have a listview with a arraydapter custom which I fill with data that I send from the webservices and I through the class Asynctask full listiview.

Insert the Searchview since the user will be able to search for the client by name, only that he already implements the Filter but he does not look for anything and he does not send me an error.

I would like someone to guide me to know what I need to enter.

I leave my code ArrayadApter .

public class MyArrayAdapter extends ArrayAdapter<CXCPSaldoClienteProveedor> implements Filterable{

        List<CXCPSaldoClienteProveedor> original;
        List<CXCPSaldoClienteProveedor>filtered;


        public MyArrayAdapter(Context context, ArrayList<CXCPSaldoClienteProveedor> ArrayClientes) {
            super(context, 0, ArrayClientes);
            this.original = ArrayClientes;
        }

        public View getView(int position, View convertView, ViewGroup parent) {

            CXCPSaldoClienteProveedor O_Cliente = getItem(position);

            // Check if an existing view is being reused, otherwise inflate the view
            if (convertView == null) {
                convertView = LayoutInflater.from(getContext()).inflate(R.layout.row_cliente, parent, false);
            }

            //INICIALIZAR FORMAT
            DecimalFormat numberFormat = new DecimalFormat("###,##0.00");

            ((TextView) convertView.findViewById(R.id.nombrecli)).setText(O_Cliente.getClienteDescripcion());
            ((TextView) convertView.findViewById(R.id.nombrecli)).setTag(O_Cliente);

            ((TextView) convertView.findViewById(R.id.txtsaldov)).setText(numberFormat.format(O_Cliente.getSaldoVencido()));
            ((TextView) convertView.findViewById(R.id.txtsaldot)).setText(numberFormat.format(O_Cliente.getSaldo()));

            ((TextView) convertView.findViewById(R.id.idcliente)).setText(String.valueOf(O_Cliente.getCliente()));
            //((TextView) convertView.findViewById(R.id.clienid)).setTag(O_Cliente);

            // Se almacena en settag el objeto Cliente
            convertView.setTag(O_Cliente);

            CXCPSaldoClienteProveedor item = getItem(position);

            //Devolver al ListView la fila creada
            return convertView;
        }

Class filter

                    final FilterResults filterResults  = new FilterResults();
                    final ArrayList<CXCPSaldoClienteProveedor> Values = new ArrayList<CXCPSaldoClienteProveedor>();
                    if(constraint != null && original!=null) {
                        int length=original.size();
                        int i=0;
                        while(i<length){
                            CXCPSaldoClienteProveedor item=original.get(i);
                            //do whatever you wanna do here
                            //adding result set output array

                            Values.add(item);

                            i++;
                        }
                        //following two lines is very important
                        //as publish result can only take FilterResults objects
                        filterResults.values = Values;
                        filterResults.count = Values.size();
                    }

Edit: Solution

After investigating and doing tests, I finally managed to solve the problem to this question, which was that it did not work, I leave the solution that was only a line of code.

public boolean onCreateOptionsMenu(android.view.Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_cliente, menu);

        final MenuItem searchItem = menu.findItem(R.id.action_search);
        final SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
        if (searchView != null) {
            searchView.setQueryHint(getString(R.string.search));
            searchView.setMaxWidth(2129960);
            searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
                @Override
                public boolean onQueryTextChange(String newText) {
                    adaptador.getFilter().filter(newText);
                    return true;
                }

                @Override
                public boolean onQueryTextSubmit(String query) {
                    // this is your adapter that will be filtered
                    System.out.println("on text submit text: " + query);
                    return true;
                }
            });
        }
