This can be done by setting a OnItemSelectedListener on your spinner. Beneath is an example:

    spin.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> parent, View view,
                int position, long id) {

            String country = (String)AdapterCountries.get(postion);
            Toast.makeText(<YourActivityNameHere>.this, "You selected " + country, Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {
        }
    }
    );
