ViewPager recache pages

When I add page after current page, and flip to it, I see not added page, but cached page.

Is this possible recache pages manually after adding new page if new page is near current page?

P.S. notifyDataSetChanged() in adapter doesn't help.

I apologize as I can't comment so this will have to do as an answer:

This will depend on the adapter you wrote or are using, and the exact method. Namely, if you were using a customized adapter with the appropriate overridden methods [which would be best for anything fairly complicated like this]:

  1. When you add the new fragment/page, add it to the internal list within the page [which should work naturally with the other overridden functions, including getCount()]
  2. Make sure to set up the fragment appropriately and implement its lifecycle accordingly so its data changes. [Ie, this is a possible source for your bug if you're using an adapter] If you merely used the onCreate and other basic lifecycle functions, then it may be an issue where the lifecycle method already occurred so the changes won't be taken place [Possible solution: call a function in this case]

That's the basics of the issue. Without any code for the adapter and how+where it's being used, I can't say much else. Hope this helps.
