Android: setting a spinner onClickListener()

Question

Im trying to get an onClickListener to fire on a Spinner, but i get the following error: Java.lang.RuntimeException is "Don't call setOnClickListener for an AdapterView. You probably want setOnItemClickListener instead," the thing is, im sure I want to call onClickListener and NOT onItemClickListener. I found this question asked by someone else on stackOverflow, the question is here: link text

The answer stated there is:

You will have to set the Click listener on the underlying view (normally a TextView with id: android.R.id.text1) of the spinner. To do so:

Create a custom Spinner In the constructor (with attributes) create the spinner by supplying the layout android.R.layout.simple_spinner_item Do a findViewById(android.R.id.text1) to get the TextView Now set the onClickListener to the TextView

I have tried the answer noted there, but it doesnt seem to work, I get a null pointer to the TextView after I do the findViewById().

This is what im doing:

Spinner spinner = (Spinner) findViewById(R.id.spinner);    
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,R.layout.layoutspinner,dataArray);

    spinner.setAdapter(adapter);

    TextView SpinnerText = (TextView)findViewById(R.id.spinnerText);
    if(SpinnerText==null){
        System.out.println("Not found");
    }else{
        SpinnerText.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View arg0) {
                //Do something
            }           
        });
    }

layoutspinner.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView 
xmlns:android="http://schemas.android.com/apk/res/android"
              android:id="@+id/spinnerText"
              android:singleLine ="true"
              android:layout_width="fill_parent"
              android:layout_height="wrap_content"
              android:textSize="6pt"
              android:gravity="right"/>

Any idea what am I doing wrong? I'm new to stack overflow, I didnt find any way to post an aditional question to the other thread (or comment since I have to little rep) so I started a new question.

Edit:

Per recomendation I tried this:

int a = spinnerMes.getCount();
        int b = spinnerMes.getChildCount();
        System.out.println("Count ="+a);
        System.out.println("ChildCount ="+b);
        for (int i = 0; i < b; i++) {
            View v = spinnerMes.getChildAt(i);
            if(v==null){
                System.out.println("View not found");
            }else{
                v.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        //Click code
                    }
                });
            }
        }

But logCat isnt showing promising results.

10-14 16:09:08.127: INFO/System.out(3116): Count =7
10-14 16:09:08.127: INFO/System.out(3116): ChildCount =0

I have tested this on API levels 7 and 8 with same results.

this works how you want but is not ideal

public class Tester extends Activity {

String[] vals = { "here", "are", "some", "values" };
Spinner spinner;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    spinner = (Spinner) findViewById(R.id.spin);
    ArrayAdapter<String> ad = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, vals);
    spinner.setAdapter(ad);
    Log.i("", "" + spinner.getChildCount());
    Timer t = new Timer();
    t.schedule(new TimerTask() {

        @Override
        public void run() {
            int a = spinner.getCount();
            int b = spinner.getChildCount();
            System.out.println("Count =" + a);
            System.out.println("ChildCount =" + b);
            for (int i = 0; i < b; i++) {
                View v = spinner.getChildAt(i);
                if (v == null) {
                    System.out.println("View not found");
                } else {
                    v.setOnClickListener(new View.OnClickListener() {

                        @Override
                        public void onClick(View v) {
                                    Log.i("","click");
                                    }
                    });
                }
            }
        }
    }, 500);
}

}

let me know exactly how you need the spinner to behave and we can work out a better solution
