Is it possible to create/spawn an object into a different layout?

I want the player to collect items in the game and then would like them to be able to view these in a 'wallet' on the home screen which is a different layout, can this be done?

Yes you would go to the home layout, or you can create the thing you mentioned on a new layer in the current layout and make it visible.

Thanks Lionz. Do you know if I can create an object in a separate layout but still remain in the same one? Then when the user goes back to the home screen, their collectables are already there, ready to view in the 'wallet'.

Not like you're describing, when you are in one layout it is like the others don't exist. You can go to the other layout and load data though. What you're describing is probably done with array data, you store collected items in there and load them in the wallet layout.
