Question

I am trying to use a static class to pass value to a view instead of using intent as I have to pass a large amount of data. Sometimes I get this error and couldn\'t find out wha

Answer 1

look at your code:

 @Override
        public int getItemPosition(Object object) {
            return POSITION_NONE;
        }

this code is use to refresh view when view change. it is also called notifyDataSetChanged()

its optional ovverride method so you can remove it.

Take a look at this answer: ViewPager PagerAdapter not updating the View

or else you can Change the FragmentStatePagerAdapter to FragmentPagerAdapter
