spinner.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {

            spinner.setSelectedItem(5);
        }

        @Override

        }
    });

Answer 2

Solved: I guess the main problem was the custom spinner adapter. This works fine now

if (spinner.getCount() > 0) {
    pos = spinner.getSelectedItemPosition();
}
MySpinnerAdapter adapter = new MySpinnerAdapter(context, myNewObjects);
spinner.setAdapter(adapter);
spinner.setSelection(pos); // needed
adapter.notifyDataSetChanged();

Answer 3

Did u tried notifydatasetChanged() or notifydatasetInvalidate() method of adapter.

newAdapter.notifydatasetChanged()
