Hi Birkir,

Above are some examples of how to do this as I have never created this functionality in an app myself with this technique.


To Ajay about your comment

Although it is not possible to change the "Double tap to" string but it could be made more contextual by changing the action e.g. "Double tap to like":

You cannot change the "Double tap to" because ViewCompat is changing the "click" and "LongClick" actions which always require a double tap gesture with TalkBack.

If you look at the second link, their "LongClick" action pulls up a menu of new options that are accessible to non-TalkBack users through a "tap and drag left/right" gesture

If you are using a custom gesture that is not a "Click" or "LongClick", you will have to create a custom AccessibilityEvent tracking that gesture and providing feedback to Android that can be passed to TalkBack. Creating this level of custom control is beyond my current knowledge.
