Hi Kostya,
I have a GalleryView in my ViewStub and I dynamically add images to
the Gallery. I would like to control from a menu option, the
visibility of the complete ViewStub view. So basically, when the
ViewStub is up displaying the gallery and I press the menu option, the
whole view gets hidden but the content (i.e. Gallery items) remain in
the stub. On pressing menu option again, the whole view is displayed
again with the gallery items selected earlier.
I don't know what you mean by replacing the stub with <include> and
toggle its contents' visibility. Could you elaborate a little more?
Thanks,
Abhi
