Android Custom Spinner - What is the useable result?

Question

I have a custom spinner (customized for formatting). It works fine and shows the result of the selected array item. The string array with my data is called mydata[].

I want to do something with that result - I've tried hours of changes but, it seems I don't know what the container is for the selected result - it just displays automatically. The mNumber refers to a case select in a class (it's result is based on what's passed into-it).

My question(s) - refer to the * WHAT DO I USE HERE * shown in the code's last line:
1. What is the container for the result?
2. How to access and syntax it?

Here's the code:
Thank you!

**[declared in onCreate]**  
    Spinner spinner = (Spinner) findViewById(R.id.Spinner01);    
    MySpinnerAdapter adapter = new MySpinnerAdapter(this, R.layout.mspinner, R.id.text,mydata);   
    spinner.setAdapter(adapter);  

**[declared outside of onCreate]**  
    @SuppressWarnings("unchecked")  
    private class MySpinnerAdapter extends ArrayAdapter{  
    public MySpinnerAdapter(Context context, int resource, int textViewResourceId, String[] objects) {  
    super(context, resource, textViewResourceId, objects);  
    final TextView woof =(TextView)findViewById(R.id.TextView07);  
    woof.setText(String.valueOf(dogday.mNumber(*** WHAT DO I USE HERE ? ***)));  
    }  
    }  

EDITED - FOR MY RESPONSE TO COMMONSWARE (too many characters for a comment box).

Thanks. You know the result that gets displayed in a spinner (by default) when something's selected - that's the piece of data I need. I want to use it as an argument for a call.

The user selects something in the spinner - The selected item will be used to make some choices in the class method (dogDay), which takes a data argument for mNumber(data) and returns a result (just like a function).

I want to do some math calcs with the result. First, I want to display what's coming back (for now) so, I'm using the dogDay.mNumber(data) as an argument for woof.text.

My question is this, How to get the piece of data (the thing the user selected in the Spinner)? How did the spinner know what to display for my selection - that's what I want? I tried using something like getSelectedItem (or whatever the it was - I can't remember just now) but, it crashes.

Is their an easier way to custom format a spinner? (and get the data) I searched hi and low for info and found only one applicable to android 1.5/later (I want a spinner with all black background and red text - I can do it via the way shown in my code using a the custom layout).

Thanks - I got a bit long winded!

EDITED - with full code Here's a full code with the custom spinner and the call you suggested. As I mentioned, I already tried it - it only shows the first item in the list - never the selected one. I use the result of getSelectedItem as an argument for the string... I tried it from both within and outside the adapter...

int poop;

/** Called when the activity is first created. */

    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    spinner.setAdapter( adapter );

    poop = spinner.getSelectedItemPosition();

        final TextView sayWhat = (TextView) findViewById(
                                            R.id.TextView01);
        sayWhat.setText(String.valueOf(mydata[poop]));

    }//end MySpinnerAdapter

Your question makes little sense to me. I am assuming that "I want to do something with that result" means "I want to find out the selected item's position in the array". If that assumption is correct, you can get the selected position for a Spinner by calling getSelectedItemPosition(). This will be 0 when the Spinner first appears, unless you change the position yourself.

Your code is also very strange, IMHO. The constructor of an ArrayAdapter should not be attempting to manipulate a widget.
