Save and Restore state of Selected list of RecycleView in fragment on TabLayout or ViewPager



Add This Line To viewPager:-

 viewPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(viewPager);
viewPager.setOffscreenPageLimit(4);

Here 4 is the Number of Tabs.
If you have 3 tabs change to :-

 viewPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(viewPager);
viewPager.setOffscreenPageLimit(3);
