Adding Text to a PreferenceFragment

I'm trying to add some text to the bottom of a PreferenceFragment. The data will will be some copyright info with a link that is used to send email. Everything compiles. When the code runs, I don't see anything on the screen. When I step through my code, I'm the textview is not a null reference, so i think that the textview access is correct. Any ideas how to get the text to be displayed or a different way to add text, or a textview, to a preference fragment.

I've got the following code in preference fragment in my OnCreate:

public override void OnCreate (Bundle savedInstanceState) { base.OnCreate (savedInstanceState);

        app = (ConstructionApplication)this.Activity.Application;
        _prefs =  this.Activity.GetPreferences(FileCreationMode.WorldReadable);

        //Load view
        AddPreferencesFromResource (Resource.Xml.Preferences);
                    // load up my other preferences

        Preference copyright = (Preference)FindPreference ("prefcopyright");
        var v = copyright.GetView (null, null);
        var cr = v.FindViewById<TextView> (Resource.Id.copyRightOnSettings);
        cr.TextFormatted = Html.FromHtml(app.Copyright);
        cr.SetBackgroundColor (Color.White);
        cr.Gravity= GravityFlags.Center;

        SetHasOptionsMenu (true);
    }

My Resources/xml/Preferences.xml file content is: <?xml version="1.0" encoding="utf-8"?>
