Wizard Pager is a library that provides an example implementation of a Wizard UI on Android, it's based of Roman Nurik's wizard pager (https://github.com/romannurik/android-wizardpager)
If you need to put a different key or an id, just create a custom Page and override the getKey() method, then when you retrieve keys make sure that you use the same key
I have a problem when I use the same title on 2 views, you use titles as keys in your implementation so there are in conflict
