firstSpinner.setOnItemSelectedListener(this); secondSpinner.setOnItemSelectedListener(this); @Override public void onItemSelected(AdapterView<?> parent, View v, int position, long id) { Spinner spinner = (Spinner) parent; switch (spinner.getId()) { case R.id.first_spinner: // item selected on the first spinner // use position break; case R.id.second_spinner: // item selected on the second spinner // use position break; default: break; } }
