java - Is there a way to use setOnClickListener with an Android Spinner?

The java.lang.RuntimeException is "Don't call setOnClickListener for an AdapterView. You probably want setOnItemClickListener instead," but that is not correct. I am using setOnItemClickListener to do some stuff based on the new selection, but I also need to do some stuff before the user changes the selection. Specifically, I am collecting data for each selection that needs to be saved to a file before moving to another selection, since the other selection is associated with different set of data. Is there a way to use setOnClickListener with an Android Spinner?

spinner.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        // Do some stuff before the user changes the selection
        ...

spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parent,
            View view, int pos, long id) {
            // Do some stuff based onItemSelected
            ...

You can replicate the an onclick event using ontouch events

    this.spinner=(Spinner)findViewById(R.id.spinner);
    this.spinner.setClickable(false);
    this.spinner.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            Log.v(TAG, "spinner touch");

            //replicating a click
            if(event.getAction() == MotionEvent.ACTION_UP){
                v.playSoundEffect(android.view.SoundEffectConstants.CLICK);
            }
            return true;
        }
    });
