Problem :
I personalized my actionBar (SupportActionBar) with a renderer on my CustomNavigationPage beacause I use AppCompat theme. So, I added my CustomView (a SearchBar) in the actionbar from this class.
But ... when we change the orientation (Portrait->Landscape / Landscape->Portrait) my view disappear and I must recreate my CustomNavigationPage if I want to see again my CustomView.
I need your help, thank you in advance !
