Resume all fragments at once in viewpager/viewpager2 on calling onResume() method

Question

When we override onResume() method in any fragment of a viewpager, we notice that it is actually resumed only when viewpager is scrolled to that particular fragment page.

So, how to resume all fragments of a viewpager together?

Answer 1

call setOffscreenPageLimit with a number higher than half your fragments. This will force the viewpager to create and keep all of the fragments created as you have in your adapter.

viewPager.setOffscreenPageLimit(2);
viewPager.setAdapter(pagerAdapter);

Here I assumed 2 as the total number of fragments in viewpager
