Reusing views vs creating new views. Performance-wise

I have an application that lets you flip through cards in a deck.

Would it be better to reuse maybe 2-3 views(cards) and just change the text/image on them.

Or should i recreate(inflate) a new view(card) each time?

Performance wise which is better?

Reusing is always better performance wise. Think about it- if you create new ones, you have to create these large objects, then set values to various properties. If you reuse, you just set the values. Creation is a superset of the work you do or reuse. If you want to see the difference, create a relatively complex ListView. Run it with full recycling. Then run it where you create a new View for each getView call. That performance difference is due to creation.

Now the question is if its enough of a bonus to be worth doing. If the number of subviews is small enough, maybe not. As the complexity of the views and the number of them increase, then it is.
