/src folder is empty unable to use

My project is mature and uses non-support fragments. Changing the code base to use support fragments is non-trivial. It would be neat if your library supported both types. :)

If using inside an Activity, works as expected.
If used inside a fragment, throws:

"java.lang.IllegalStateException: The application's PagerAdapter changed the adapter's contents without calling PagerAdapter#notifyDataSetChanged! Expected adapter item count: 3, found: 5"

"final Bundle savedFragmentState = f.mSavedFragmentState;" - Not found this field! Not build.

Update

I fixed half of my issue and made a second post (below). There's still a problem, but at least it's scrolling infinitely now

Original

I'm brand new to Android development, so forgive any terrible code or lack of understanding of simple concepts (like the difference between an Activity and a Fragment)

For my work I was asked to create a simple app with 3 screens that you could cycle between with a swipe, and on each of these screens we wanted a streaming video (same subject, different angles). Because Android supports OpenGL I know that in the worst-case scenario this is guaranteed to be possible by drawing all of the content to the screen myself, but Android had a lot of built-in UI components that seemed to make the job easier. Unfortunately I quickly learned that the ViewPager wouldn't meet my needs - as every solution online suggests you need at least 4 screens (I want 3) and their suggestion of having getCount() return Integer.MAX_VALUE means you can swipe right infinitely, but you still hit 0 if you swipe left.

Then I found this library - and the demo worked perfectly. I believe this will do everything I need. But when I tried to implement it in my project, I got the following behavior:

Load app: Displays screen A
Swipe left: Failed (hit the edge)
Swipe right: Displays screen A
Swipe right: Displays screen B
Swipe right: Displays screen C
Swipe right: Displays screen A
Swipe right: Failed (hit the edge)
Swipe left: Briefly displays screen C, then switches to screen B when the animation completes
Swipe left: Displays screen B again
Swipe left: Displays screen A
Swipe left: Displays screen C
Swipe left: Failed (hit the edge)

Here's a link to the repository where I temporarily uploaded my code (I've removed the license key for our Red5 streaming server from the code, so the video won't work -- but there's a red bar at the bottom of each screen which reads "test 1", "test 2", and "test 3" for each screen)

I'm not sure if I'm doing something wrong or if I found a bug in the library.

i have a grid view inside viewPagerFragment when i scrolling view pager it shine at the "end" of item. i mean at the first item or last item that repeated. i set view pager and grid view "overScrollMode="never" ",in xml and java code, but the problem not solved!

It do not scroll properly, when i am on last page, and swipe right, it sets item on first index instead of 0th index and vice versa.

I tried to reinitialize like this

viewpager.setAdapter(new BranchCircularViewPagerAdapter(getApplicationContext(), getSupportFragmentManager(), temp)); final CircularViewPagerHandler circularViewPagerHandler = new CircularViewPagerHandler(viewpager); circularViewPagerHandler.setOnPageChangeListener(createOnPageChangeListener()); viewpager.addOnPageChangeListener(circularViewPagerHandler);

But it previous fragment is still there it wont remove..

how to create shape in circular and put this viewpager at bottom of the screen so that user can keep rotating as arc menu

Hi, and thanks for this library. I can't get setCurrentItem to work properly - the item I set is always off by one. The only way seems to be to use a "+1" when I invoke setCurrentItem, so for instance: if the user clicks on the item 0, I need to launch the pager and use setCurrentPager(1).
Is this somehow expected by the CircularViewPager? I see that in the CircularViewPagerHandler constructor, the current item is set at 1 by default and not at 0.
Thanks for any hint.
