                .setUseAutoRemoveTutorialFragment(true)
                .setUseInfiniteScroll(true)
                .setPagesColors(mPagesColors)
                .setPagesCount(TOTAL_PAGES)
                .setIndicatorOptions(indicatorOptions)
                .setTutorialPageProvider(new TutorialPagesProvider())
                .setOnSkipClickListener(new OnSkipClickListener(this))
                .build();
        final TutorialFragment tutorialFragment = TutorialFragment.newInstance(tutorialOptions);
        getFragmentManager()
                .beginTransaction()
                .replace(R.id.container, tutorialFragment)
                .commit();



//This is the test, but tutorialOptions return any options in null
(ImageView) imgView = (ImageView)tutorialOptions.getActivity().findViewById(R.id.img_view_test);

if(imgView != null){

} 
}

You should learn basics of using of fragments. When you call getFragmentManager().commit(), it posts operation to queue so fragment will be added to screen asynchronously. When you then try to find an image view, it's not added to view hierarchy yet. See Javadoc of commit method:

Schedules a commit of this transaction. The commit does not happen immediately; it will be scheduled as work on the main thread to be done the next time that thread is ready.

But you can use commitNow method instead.

Also note:

1. Do not ever use views from fragments in other Android components (i.e. activities, other fragments). Only fragment that displays that view must find and use it. So if you need to interact with image view, do it in the fragment.
2. TutorialOptions instance used by this library's internal components. You don't need to use it at all. Just construct it and pass to TutorialFragment.

According to the title of this issue Add findViewById in fragment method of library:

It's you who decide which fragments to use. If you need to interact with views of your fragment, then create your own fragment and extend it from PageFragment. There you can manipulate fragment's views. Then you should use TutorialPageProvider instead TutorialPageOptionsProvider. See Configure Tutorial Pages: Via TutorialPageProvider.
