Android “Best Practice” returning values from a dialog

Question

What is the \"correct\" way to return the values to the calling activity from a complex custom dialog - say, text fields, date or time picker, a bunch of radio buttons, etc,

Answer 1

I'm using following way:

1. All my activities has one and the same parent Activity (let's say ControlActivity). ControlActivity has private volatile Bundle controlBundle; with appropriate getter/setter

2. When I start dialog, I used to call dialog thru my own method:

   public void showMyDialog(int id, Bundle bundle)
   {
       this.controlBundle=bundle;
       this.showDialog(id, bundle);
   }
   

So each time I know parameters sent to dialog

3. When dialog is about to complete, I'm forming in dialog another Bundle with necessary values and then put them thru my Activity bundle setter:

((ControlActivity )this.getOwnerActivity).setControlBundle(bundle);

So in the end when dialog finishes I know value "returned" from dialog. I know that it's not like int retCode=this.showMyDialog(); it's a bit more complex, but it's workable.
