ViewStub vs. View.GONE

As far as I undestand开发者_开发百科, 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?

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.
