Ошибка сообщения Spinner

Question

У меня проблема со счетчиком. Когда я автоматически открываю класс (где есть прядильщик), он выбирает меня последним элементом в списке, но не показывает мне сообщение в тосте. И когда я выбираю элемент, щелкая по нему, они появляются мне сообщение. Что не так в моем коде?

Вот мой код:

public class SelectCodIncidence extends Activity {

private ArrayList<String> datos;
protected netAppApplication app;
Spinner sp;  
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.codigoincidencia);
    datos = new ArrayList<String>();
    //datosCod = new ArrayList<String>();

    try {
        NotesCenter messageCenter = new NotesCenterImpl();

        List<CodIncidence> codincidence = messageCenter.getCodIncidence();                                      
        for (CodIncidence e : codincidence) {
            //datosCod.add("1");
            datos.add(e.id);

        }   
        } catch (Exception ex) {
        //  showMessage(ex);
            Log.v("blah", ex.getMessage());


        }
    sp = (Spinner)findViewById(R.id.spinner);

    ArrayAdapter<String> adaptador = 
            new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, datos);  
    sp.setAdapter(adaptador);

    sp.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

        public void onItemSelected(AdapterView<?> arg0, android.view.View arg1, int arg2, long arg3) {

                   int count = sp.getCount(); 
                if (count > 0){
                    sp.setSelection(count -1,true);

                    int item = sp.getSelectedItemPosition();

                     Toast.makeText(getBaseContext(), 

                                "Incidence Selected: " + datos.get(item), 
                                Toast.LENGTH_SHORT).show();

                }

            }
        public void onNothingSelected(AdapterView<?> arg0) {
            return;
        }

    });
    }
  }
}

Answer 1

положи тост сразу после этого условия как указано ниже

 if (count > 0){
    sp.setSelection(count-1,true);
     Toast.makeText(getBaseContext(), 
                "Incidence Selected: " + datos.get(item), 
                Toast.LENGTH_SHORT).show();
