Are you worried about not by clicking on the TAB switch to ViewPaeer?

[parin9097]

Yes exactly i want to achieve this thing.

On click of these tabs i want to open their layouts in viewpager.

Thanks.

[panpf]

You need to call pagerSlidingTabStrip.setViewPager(viewPager) method to bind the ViewPager, PagerSlidingTabStrip will monitor the TAB Click events and ViewPager switching

[parin9097]

yes i know that but how can i set my layout in viewpager and can flip the layouts in viewpager

[panpf]

You can't use ViewPager?

I have a ViewPager, and FragmentPagerAdpater and 3 Fragments to implement an tab swipe view. Is the ViewPager supposed to "remember" the 3 views after first time rendering?

My problem is that after some time, the layouts of the 3 views are "forgotten". That means I need to update them again and user will see the ugly part before updating.

Is there a view holder pattern for viewpager as well? What technique can i use to remain those already rendered views or preventing them being destroyed?

[panpf]

call ViewPager.setOffscreenPageLimit(3)
