Re: [android-developers] Handling Adjacent Fragments in ViewPager Contributing to Options Menu

Write your own adapter.  ViewPager knows nothing about fragments; that is the job of the adapter.

You can take one of the existing adapters and modify it to do what you want; they are not very complicated.

Hi! I think it may be a little bit offtopic, but as you are talking about changing PageAdapter and ViewPager apis, I'd like to ask if it is possible to expose some method to get the fragment after you have added it to a ViewPager. 

I'm asking that because if you have to handle a ScreenOrientation after the fragment has been added, there is no way to get a reference to them later, unless you keep a reference to your fragments in a static variable. Another approach I used was to use the FragmentManager.putFragment() method to keep the fragment reference for me.

I noticed the FragmentPagerAdapter adds the fragments with a tag based on his position and parent id through the method makeFragmentName. I think it would be nice if external code could get access to this method so we could have access to the fragments inside the viewpager through the findFragmentByTag().

Thanks in advance.
