android arrayAdapter with autocomletetextview not working with List<...>

Question

1) The code below : getView does not get called when I type in autocompletetextview. Watch out the list in the fragment and the adapter class extending List

   public class SigninFragment extends Fragment {
        private List<Test> list= null;

@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    Test tes= new Test ();
    tes.setId(1);
    tes.setDesc("descabc");
    list= new ArrayList<>();
    list.add(prof);

    tesListAdapter =
            new TesListAdapter(
                    rootView.getContext()
                    ,R.layout.list_row_adapter
                    ,list);

    autocompletetextview.setThreshold(3);
    autocompletetextview.setAdapter(tesListAdapter );

My Adapter Class :

public class ProfissoesListAdapter extends ArrayAdapter<Test> { **<==HERE**
    private LayoutInflater inflater;
    private int resource;

public TesListAdapter(Context activity, int resource, List<Test> listaProf) **<==HERE**{

    super(activity, resource, listaProf);
    this.inflater = (LayoutInflater) activity
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    this.resource = resource;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder holder;

...

2) The code below : YES... getView() does get called when I type in autocompletetextview. watch out in the fragment the String[] array and the adapter exteding ArrayAdapter

   public class SigninFragment extends Fragment {
        private List<Test> list= null;

@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);


    String[] list =  {"abcde","bbbbbb","bbbakaka","ccccccc","dddddd"};

    tesListAdapter =
            new TesListAdapter(
                    rootView.getContext()
                    ,R.layout.list_row_adapter
                    ,list);

    autocompletetextview.setThreshold(3);
    autocompletetextview.setAdapter(tesListAdapter );

My Adapter Class :

public class ProfissoesListAdapter extends ArrayAdapter<String> {  **<==HERE**
    private LayoutInflater inflater;
    private int resource;

public TesListAdapter(Context activity, int resource, String[] listaProf) {  **<==HERE**

    super(activity, resource, listaProf);
    this.inflater = (LayoutInflater) activity
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    this.resource = resource;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder holder;

...

In the first case getView() doesn't get called because it doesn't match what you type in the autocomplete widget. The problem is that, when used with a custom class(not String/CharSequence), ArrayAdapter gets the data by calling toString() on the data object(in your case the Test's toString() method).

If you haven't overridden that method to return something meaningful(like the value set with setDesc()) it will return something like this Test@(somenumbershere) which will not match what you type as a filter. So, the key is to provide a proper toString() method.
