Android talkback; how to disable announcing cell position and cell count?

When I have a recycler view with 12 items, when accessibility focus goes onto cell number 3, for example, talkback announces "Double tap to activate. Item 3 of 12".

I want to keep the action but stop it from announcing the item position and item count. How can I do this? I have tried to assign a delegate to the recycler view but not sure what to override in the delegate.

How can I do this?

So I figured it out. An AccessibilityNodeInfo has a method called SetCollectionInfo(). CollectionInfo has properties like rowCont and columnCount. I simply set the info to null.

Note, the below is xamarin:

    private class TabLayoutTabAccessibilityDelegate: View.AccessibilityDelegate
    {
        public override void OnInitializeAccessibilityNodeInfo(View host, AccessibilityNodeInfo info)
        {
            base.OnInitializeAccessibilityNodeInfo(host, info);
            info.SetCollectionInfo(null);
        }
    }

This is a functionality that should not be disabled: it lets people using Talkback know that they are in a list, how long is the list, which element is currently focused (are there more elements above/below).
