I have an Activity with a fragment called MainFragment which has a ViewPager2 to display a few Fragments. One of which is SearchFragment. SearchFragment has an EditText with a TextWatcher, upon text change, an API call is being made to fetch the suggestions. When I'm setting these suggestions to a RecyclerView which is shown right below the EditText, it won't get updated unless I touch the RecyclerView.

I've tried running a Handler to make the API call and update the RecyclerView without letting the EditText gain Focus, and it worked. RecyclerView updates the Data just fine when EditText is not Focused.

  • Can you share more details? (Fragment and Adapter classes) Are you calling notifyDataSetChanged after the API result? – Hamza Khan Nov 11 '19 at 10:43
  • I'm afraid I can't do that. I'll make a dummy Project and share that. – v15h4l Nov 11 '19 at 10:52
  • Thank you for the reply @HamzaKhan. The issue is resolved now. There was a bug in ViewPager2 library, updated it, and it's working now. – v15h4l Nov 11 '19 at 18:07

There was a problem with ViewPager2 Library.

I was using "androidx.viewpager2:viewpager2:1.0.0-beta05" which had a Bug that would cause View Elements to lose focus if EditText is in Focus.

Updated to "androidx.viewpager2:viewpager2:1.0.0-rc01" and Issue is resolved now.
