This seems to me as the desired behavior.  If there were a large number of hidden items that you were forced to swipe through it could be inefficient though.

I suppose the user could be advised in the contentDescription property if this is a native app.  I don't think the API is rich enough to indicate the number of items or what is shown any other way.  However, when you use contentDescription for additional purposes you can run into challenges with localization, etc.

Subject: Talkback and horizontal scroll

Hi All,

I am testing a mobile app which has social media and other image links (about 8 links) towards the end of the screen.
These items are in layed out in one line and has a horizontal scroll.

When the page loads for the first time, this slightly animates to let the users know that there are more items that can be scrolled to.
The last visible item on-screen is chopped, which is another way to tell the users that there are more items and that they can scroll.

Visually I don't see a problem. However I noticed that when I choose to read from top option, TalkBack reads only the visible items on screen. When I swipe from left to right one element after another, all the hidden items receive focus.

Is this a TalkBack limitation. How can we let screen reader users know that there are more items to the right and they need to scroll to access?

Thanks in advance.

Regards,
Madhavi.
