android - installation-like form dialog box -

i've got problem dialog box. i'd installation-like form asks question type / choose option. @ moment did simple dialog box shows layout spinner. ideas should create new dialog box on "next" button (or maybe somehow change layout of current dialog box?) asks next question?

picture:

my code:

public class dialog_box extends sherlockdialogfragment  {     @override     public dialog oncreatedialog(bundle savedinstancestate) {          final alertdialog.builder builder = new alertdialog.builder(getactivity());         final layoutinflater inflater = getactivity().getlayoutinflater();         builder.setview(inflater.inflate(r.layout.my_layout, null));         builder                .settitle("question i")                .setpositivebutton(r.string.next, new dialoginterface.onclicklistener() {                    public void onclick(dialoginterface dialog, int id) {                      }                })                .setnegativebutton(r.string.cancel, new dialoginterface.onclicklistener() {                    public void onclick(dialoginterface dialog, int id) {                      }                });         return builder.create();     } } 

you this:

implement function creates dialog , receives int question number

createdialog(int questionnumber) 

in function can have switch-case title , content, , after switch set next button call

dismiss(); createdialog(++questionnumber); 

this close current one, , construct next one.

the first 1 can call different button using createdialog(0);

also, @ beginning of method, should check if last one, assuming have 5 dialogs:

max_dialogs = 5;  if (questionnumber >= max_dialogs) {     return; } 

you still have code every dialog, there's no getting around it.
