Please include a sample project that reproduces your issue.

be...@gmail.com <be...@gmail.com> #3Jun 21, 2022 05:53PM

Here is the sample project.

Steps to reproduce:
1. Press on "Search" icon;
2. Write something;
3. Search this text, keyboard will be dismissed;
4. Tap on "Dialog" button;
5. Dissmiss dialog;

With the new 1.5.0 fragment library version text will be cleared in the search box after dismissing dialog.
In the version 1.4.1 and lower text in the search is not clearing and this is correct behaviour.

Please suggest some workarounds or how to fix this issue?

Hello, have you checked sample project? I hope it will help find the issue.

I've described a weird workaround that I got, here:

It probably has bugs of its own that I didn't think of.
Google please fix this.

Hello I raised similar issue with this ticket https://issuetracker.google.com/issues/249247706

This makes the SearchView unusable/broken when fragments are changed (i.e base on searchView input query)

What can we do to fix this problem? What is the progress of work on solving this problem?

Hi, i am also facing this issue after we dismiss a DialogFragment, the callback comes in the onPrepareOptionsMenu(), which is causing the issues for me.
Any idea on when it will be fixed?

Facing a similar kind of issue when scrolling the fragments using a ViewPager.

Can you update regarding any progress on this issue.

jb...@google.com <jb...@google.com> #12Mar 21, 2023 10:04PM

Marked as fixed.

I wonder if the new SearchBar has this issue:

Add check to only invalidate options menu when contributing menu items

FragmentManager previously appropriately only added
a MenuProvider when the host is a MenuHost **and**
we are at the root fragment that is providing the
menu items. This behavior should be mirrored when
removing a MenuProvider as well, so that only
components that directly contribute menu items will
invalidate the options menu.

Bug: 244336571
Test: all tests pass
