Answer 1

To avoid reaching back into items[] from the listener use getItemAtPosition which returns an Object from the Adapter. To access the MyData methods you must cast the object like so:

public void onItemSelected(
        AdapterView parent, View view, int position, long id) {
    MyData d = (MyData) parent.getItemAtPosition(position);
    valueTextView.setText( d.getValue() );
}
