How to ignore some UI elements as seperators or ImageViews for Talkback?

Question

I tried Talkback accessibility service on my app.

When I navigate through my app I have:

some line seperators, where Talkback reacts sensitive and talks something on that seperator which does not make any sense.
images beneath its explanation text, where talkback reacts sensitive to the images, instead of jumping to the text beneath and read the text here.

How can I ignore UI elements like seperators completely?
How can I ignore some certain designated images and navigate to their text explanation beneath instead?

Kudos for implementing/testing accessibility in your app!

To disable accessibility behavior, since API 16 you can use the android:importantForAccessibility="no" attribute, or programmatically via

myView.setImportantForAccessibility(View.IMPORTANT_FOR_ACCESSIBILITY_NO)

or

ViewCompat.setImportantForAccessibility(myView, ViewCompat.IMPORTANT_FOR_ACCESSIBILITY_NO);

To ignore some certain designated images and use their text explanation beneath you can set the text explanation as the contentDescription on the image. Talkback will read a views contentDescription.

myImageView.setContentDescription (string-value-from-caption)

Since I do not use any layouts anymore and I only have Composables .. what would be the pendant for Jetpack Compose? There is a `Modifier.toggleable`? – Ralf Wickum Jun 23 '21 at 13:44
Sorry I don't know Compose. You might try setting `contentDescription=null`? – CSmith Jun 23 '21 at 17:39
Its still selectable and navigatable with nulling contentDescription – Ralf Wickum Jun 25 '21 at 08:11
For Compose `Modifier.clearAndSetSemantics { }` should ignore the View – Steffen Funke Nov 15 '21 at 16:31
