ViewStub vs. View.GONE

Question

As far as I undestand, neither a ViewStub nor a View that's GONE participate in the measure and layout passes (or rendering anyway).

Is there a difference in rendering performance? What's the best practice about when to use which?

Answer 1

The rendering performance comes into picture when you are inflating the views.

My guess is that its much cheaper to inflate a ViewStub than to inflate a View, either from XML or by changing visibility. ViewStub is especially used when you need to add/remove (indefinite) views (eg. add phone numbers to a given contact). Hope this is what you were looking for.
