Navigate between headings with swipe while using talkback

Question

Android 9 has introduced accessibilityHeading tag, which can be used by talkback to announce the Headings.

Look for Heading-based navigation

In my app I have multiple Textviews in my activity with some Headings

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginBottom="10dp"
            android:accessibilityHeading="true"
            android:text="Accessibility Heading 1"
            android:textColor="#000000"
            android:textSize="18sp" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginBottom="20dp"
            android:text="Message"
            android:textColor="#000000" />

But when I run the app, headings are treated as normal textviews only and no special treatment is given by Talkback.

I can swipe left to navigate through all elements. There is option to swipe up to change mode for talkback announcements. e.g Default, Links, Controls, Headings etc.

When chosen Headings, I expect talkback to announce only headings and to jump from one heading to another but it stays at the same place even after Swipe Left or Swipe Right gesture.

Set both accessibilityHeading and focusableInTouchMode to true. Then, after setting the navigation mode to Headers (you can do this via the up down gesture), swiping up or down navigates you though the headers. Swiping right and left will still allow you to navigate through single items.
