элемент не выбирается из выпадающего списка

Question

Элемент не выбирается из раскрывающегося меню. Даже если он выбирается, почему он не появляется в TextView?

Кроме того, я получаю эти странные точки после каждого элемента, который я извлекаю из базы данных Microsoft SQL Server.

@Override 
public void onItemSelected(AdapterView<?> parent, View view, 
            int position, long id) { 
    choosenItem = dynamicSpinner.getItemAtPosition(position).toString(); 
    Log.v("item", choosenItem); 
    TextView show = (TextView) findViewById(R.id.show); 
    show.setText(choosenItem);
