Thanks Joe and Mallory for your thoughts!

Just found out that with viewCompat it is possible to modify default "Double tap to activate" hint.

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".

The below might be possible, but this is something Google should address in the API. Providing a Hint property via their accessibility API and linking it to TalkBack. Then the user can control if they want to hear hints or not. As a screen reader user, I would get rather annoyed hearing "double tap to like" each time I came across a control on the screen. Especially if it occurs multiple times on the same screen. I suspect you have thought of this, but will raise it anyway. Make sure it doesn't break the standard hint "Double Tap" anywhere else in the app.

The other thing to think of is if your label is descriptive enough. This is the way I would tackle it, rather than changing standard API properties.

How do you use viewCompat to change the spoken hint (after "double tap
to"), I am curious, could you post a code snippet?

Hi Birkir,

https://blog.novoda.com/customising-usage-hints-for-android-talkback/

https://overflow.buffer.com/2018/09/05/announce-actions/

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.
