On iOS you can move focus by posting a notification with a layout change and include the control to focus as the second parameter.

UIAccessibilityPostNotification(UIAccessibilityLayoutChangedNotification,
controlToFocus);


On Android you typically have to allow the control to be focusable by setting setFocusable, etc. and then attempt to request focus. For controls that don't take typical focus you will likely need to create an accessibility focus event and dispatch the event using sendAccessibilityEvent. It's been a while since I played with this so I can't recall the specifics without researching it.

Subject: [WebAIM] Focus handling on Native App

Native app experts - Can anyone advise the coding best practice for native app focus handling?

Say clicking on a link opens the action sheet/bottom sheet on the native app, how the focus move be coded for screen readers?

Like in web applications, there are ways to handle the focus using tabindex, javascript, etc.

Thanks,
Poornima.
