Question

In my application I am using ViewPager from the support library- v4

1. In main screen I have viewPager which got max 5 Fragment, all fragment belongs to one class ArticlePager

2. Now in main screen there are list on categories, now the content of the pager is based on that selection,

The problem I am having is, I have used FragmentPagerAdapterwhich stores the Fragment and if the fragment is already exist, It will return the old Fragment without recreating it. That things runs perfectly, but Problem Occurs @ the time of orientation change.

For instance

If there are 5 View normally in every fragment For the given position, but There are also some which contains 2-3 views. Now if I change the orientation on page No. lets say 5 which contains only 3 view inside.

So, by now in every category on Page 5 I’ll got the view containing 3 view, which is not something I want.

In my application each category contains the pagination

Is there any way such that i can destroy and recreate the Fragment on click of category? or any other work around

Thank you

OK thanks to open source I find my solution, FragmentPagerAdapter I have override the method instantiateItem and got the solution.

This can be easily achieved by FragmentStatePagerAdapter such that it doesn’t store the fragment. It recreate it all the time, but I don’t want that in 100’s of page because of only few pages.
