FragmentPagerAdapter deprecated

Question

Since API 27 FragmentPagerAdapter is deprecated. What\'s the best alternative to use for this?

In my case, I understand something like super(fragm

Answer 1

Replace:

class MyViewPagerAdapter(manager: FragmentManager) : FragmentPagerAdapter(manager)

with:

class MyViewPagerAdapter(manager: FragmentManager) : FragmentPagerAdapter(manager, FragmentPagerAdapter.BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT)

(assuming that MyViewPagerAdapter does not need this value to be configurable)

Answer 2

It seems like not only the constructor without behavior, but the class FragmentPagerAdapter (which can consume a good amount of memory by keeping Framents in memory), and FragmentStatePagerAdapter are both in deprication stage. I wonder what can be used to extend abstract class PagerAdapter to extend codebase lifespan.

Answer 3

The javadocs actually has the following deprecation notice on FragmentPagerAdapter:

---

This class is deprecated.

Switch to ViewPager2 and use FragmentStateAdapter instead.
