created issue #1

Jun 2, 2019 11:03AM

Artifact used:
- androidx.viewpager2:viewpager2:1.0.0-alpha04

I noticed that ViewPager2 sometimes crashes with the following stack trace. Currently, I have not figured out how to reproduce the error frequently, so I will attach the procedure/sample project for reproduction later.

commit 47ac9fee0e3d43b4da33f53b8a2ff590f0d46079
Author: Jakub Gielzak <jgielzak@google.com>
Date: Tue Aug 20 13:57:06 2019

Addressed issues with EditText causing scroll

EditText methods: bringPointIntoView, and handleFocusGainInternal
trigger requestChildRectangleOnScreen in ViewPager2's internal
RecyclerView.

This can cause:
- unwanted scrolling -- e.g. when typing on some API versions
- a jump to page 0 -- EditText sometimes reports over -1M px mScrollX

This fix bypasses requestChildRectangleOnScreen calculations taking
advantage of the fact that PagerSnapHelper constraints valid scroll
values to a snapped position ones, and as a result, the problem is
reduced to choosing the correct currentItem.

Hi! I have successfully created a demo project which can reproduce this issue. Please check the following repo and I hope it helps to resolve the issue.

[UPDATE]
This issue still exists on ViewPager2 v1.0.0-alpha06 with RecyclerView v1.1.0-beta01.

I can confirm I can repro this and will try to provide a workaround / fix soon.
Big thanks for the sample app, repro steps and research info. Super appreciated!

jg...@google.com <jg...@google.com> #8Jul 16, 2019 03:53PM

The easiest workaround would involve copying FragmentStateAdapter and FragmentViewHolder into your project, and in FragmentStateAdapter adding ensureFragment(holder.getAdapterPosition()) as the first line of placeFragmentInViewHolder method. Attached as a patch to your sample app.

We'll work on a proper fix. Might unblock you in the meantime though. Thanks again for reporting and a sample app.

Fix for FragmentStateAdapter transient state issue

Fixes a crash when a ViewHolder which has gone through
onFailedToRecycleView is shown again violating Adapter's design
assumptions.
