[Android] IndicatorView does not convey correct accessibility information

[Croppo]

Description

When using a CarouselView with an IndicatorView on Android with TalkBack enabled, the accessibility behavior is inconsistent and incomplete. For example, when focusing on the IndicatorView, TalkBack initially reads “out of list”, then when navigating to the other indicator dots it does not produce any announcements, leaving the user unaware of the current carousel position.

I have attached a repository to replicate this issue.

Steps to Reproduce

1. Enable TalkBack on an Android device.
2. Navigate to open carousel view
3. Focus on the IndicatorView (dots representing carousel position).
4. Swipe to navigate to the next item in the carousel.

Expected behavior:
TalkBack should announce the current position in the carousel each time the user navigates to a new item (e.g., “Item 2 of 5”, “Item 3 of 5”, etc.).

Actual behavior:
When initially focused, TalkBack reads the first dot as “out of list” (which appears to be a placeholder or mislabel).
After swiping to the next carousel item, TalkBack does not announce any updated information about the position.
Subsequent dots are not read out, leaving the user without feedback about their current position in the carousel.
