chipGroup.getCheckedChipIds() does not seem to update

[NLLAPPS]

I don't have time to create a sample app to show the bug but chipGroup.getCheckedChipIds() does not seem to return up to date list of checked chips.

My use case is doing search as user taps and checks/unchecks filters. I used to rely on getCheckedChipIds to filter search results. Just noticed that it does not return up to date list of checked items. Cannot say which version broke it.

chipGroup.children.filter { (it as? Chip)?.isChecked ?: false }.map { it.id } works fine

Version I am using is 1.6.0

On the MDC catalog I'm able to reproduce getCheckedChipIds() returning unexpected values after the reload FAB button is clicked. Is your situation something similar? could you provide more details of the observed behaviors and what is the method returning for you?

In my case I simply call getCheckedChipIds() once user checks/unchecks one of them

Confirmed with version 1.6, was fine in 1.5.*. When a chip is checked/unchecked and its OnCheckedChangeListener called, a following call to ChipGroup.getCheckedChipIds does return the previous checked state, not taking into account the latest change.

@drchen this seems like a change in behavior due to f3c6430 which first made it into 1.6.0?

I'll take a look.

Hi so I think the root cause is that OnCheckedChangeListener.onCheckedChanged() is called before ChipGroup's internal data structure is updated.

I'll work on a fix of this. In the meantime I'll suggest you to use ChipGroup.OnCheckedStateChangeListener instead, which should work correctly.
