How do you get the selected value of a spinner — Android

public class YourItemSelectedListener implements OnItemSelectedListener {

    public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
        String selected = parent.getItemAtPosition(pos).toString();
    }

    public void onNothingSelected(AdapterView parent) {
        // Do nothing.
    }
}

Finally, your ItemSelectedListener needs to be registered in the Spinner:

spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());
