Scala on android (retrieving data from multiple custom dialogs)

Question

The problem I'm having is capturing data from my option menu dialogs. The example below has an options menu with four dialog layout to of the dialog capture a stringa that I need returned to the host activity. Can someone explain why the code below does not work. Here is a sample of my code:

class ClientConfigActivity extends Activity with TypedActivity {

// Called when the activity is first created                        
override def onCreate(savedInstanceState: Bundle) {                 
  super.onCreate(savedInstanceState)                                
  setContentView(R.layout.clientconfig)                             

  // Dialog Test                                                    
  Log.d("Option", getIntent.getExtras.get("localIP").toString)      
  Log.d("Option", getIntent.getExtras.get("remoteIP").toString)     
}                                                                   

// Relieves results from clientConfig option menu                                     
override def onActivityResult(requestCode: Int, resultCode: Int, data: Intent) {      
  super.onActivityResult(requestCode, resultCode, data)                             

  requestCode match {                                                                 
    case 0 => Log.d("Option", "Option 1 got here")                                    

      //local_IPAddress.setText("hello")                                              

    case 1 => Log.d("Option", "Option 2 got here")                                    
  }                                                                                   
}         

// Called when an options menu is created.               
override def onCreateOptionsMenu(menu: Menu) = {         
  // Inflates XML file into something that can be used.  
  val inflater = getMenuInflater                         
  inflater.inflate(R.menu.clientconfigmenu, menu)        

  super.onCreateOptionsMenu(menu)                        
}      

// Test to see which option was clicked.                                                                                           
override def onOptionsItemSelected(item: MenuItem) = {

You might want to look at your description because it's confusing and not very consistent. — thoredge, Apr 27 '12 at 14:58

What happens when you try to show the dialog?

Dialogs have a life-cycle that may seem a little strange. See http://developer.android.com/guide/topics/ui/dialogs.html for details.

You're expected to call showDialog(yourDialogId) to open the dialog. Dialog creation is done in onCreateDialog(id). Here you'll match the id to your yourDialogId and create and return the dialog.
