How to retrieve the value from dialog input field?

I am creating a dialog with the input text allow using to fill in the text with 2 button ok and exit which to continue the next process. But i dunno how to retrieve the value.. what syntax?
i will pose u the dialog code, I done the code already, i think it can work fine, just dunno where and which part to get the value.
hopefully someone can check for me.. how to get the value which user key in the text.
looking for solution with the syntax, i think it is just a simple syntax...


final class TestDialog extends Dialog{

    private EditField userNameField;
    private ButtonField okButton;
    private ButtonField cancelButton;

    public TestDialog(String choices[],int values[]){
        super("Enter a username", choices,values,Dialog.OK, Bitmap.getPredefinedBitmap(Bitmap.QUESTION), Dialog.GLOBAL_STATUS);
        userNameField = new EditField("User Name: ", "", 50, EditField.EDITABLE | EditField.FILTER_FILENAME); 
        net.rim.device.api.ui.Manager delegate = getDelegate();
        if( delegate instanceof DialogFieldManager){
            DialogFieldManager dfm = (DialogFieldManager)delegate;
            net.rim.device.api.ui.Manager manager =dfm.getCustomManager();
            if( manager != null ){
                manager.insert(userNameField, 0);              
              
            }
        }
       
    }    

   ( public String getUsernameFromField(){
    	Dialog.alert("testing111"+userNameField.getText());
    	return userNameField.getText();
    }

}



final class TestScreen extends MainScreen
{
    public TestScreen userNameField;
	private Dialog diag;
   

    public TestScreen()
    {
    	String choices[] = {"Ok","Cancel"};
        int values[] = {Dialog.OK,Dialog.CANCEL};
       
        //int values[] = {0,Dialog.OK,Dialog.CANCEL};
        
         diag = new TestDialog(choices,values);
        
        UiApplication.getUiApplication().invokeLater(new Runnable()
        {
            public void run()
            {
                int iResponse = diag.doModal();

                if(iResponse == Dialog.OK)
                {
                    //return;
                	//Dialog.alert("testing"+diag);
                	System.out.println(userNameField);
                }
                else
                {
                    System.exit(0);
                	                }               }
        });          
    }
}

your getUsernameFromField() method will return the inputted value, you'd just call it by the look of it
