In order to add an accessibility action the below line of code suffices, using ViewCompat which is backwards compatible to API 21.

ViewCompat.addAccessibilityAction(viewToAddActionTo,"String to describe what the action does", (v,b) -> actionCalled);
//a sample request would look like
ViewCompat.addAccessibilityAction(swipeLayout,"Delete Item in List",(v,b) -> deleteItem(position);

Addition of Actions in Local Context Menu

Hopefully this suffices, the action to be done i.e delete, star, archive (Similar to Gmail) can be added to custom views using this. Key Points are to figure out which View needs the action and what should the action perform.

You can add a custom action to the AccessibilityNodeInfo object inside the onInitializeAccessibilityNodeInfo method of an AccessibilityDelegate.

If the action is then selected by the user, the performAccessibilityAction method is called on the View.

In the example "myCustomAction" is the text that is displayed to the user.

MyCustomView.kt

init {
    accessibilityDelegate = object : View.AccessibilityDelegate() {
        override fun onInitializeAccessibilityNodeInfo(host: View?, info: AccessibilityNodeInfo?) {
            super.onInitializeAccessibilityNodeInfo(host, info)

            info?.addAction(AccessibilityNodeInfo.AccessibilityAction(R.id.myCustomAccessibilityEvent, "myCustomAction"));
        }
    }
}

override fun performAccessibilityAction(action: Int, arguments: Bundle?): Boolean {
    if (action == R.id.myCustomAccessibilityEvent) Log.d("TAG", "Accessibility event triggered")
    return true;
}

res/values/accessibility.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <item type="id" name="myCustomAccessibilityEvent"/>
</resources>
