How to disable/Manage Accessibility announcement on ImageView? Android

Question

My Screen has Image and Titleview. I need to announce talkback as the Title text when the page loads. But it always announces the contentDescription of an ImageView.

View Hierarichy

ImageView and then title.

What I tried ?

Tried to set focus on title, For that I set these attributes to ImageView

android:focusable="false"
android:accessibilityTraversalAfter="@id/title"
android:importantForAccessibility="no"

Bad luck, none of these worked in my case. As a second try, I added these in my fragment

onResume {

    if (accessibilityManager?.isEnabled == true) {
        activity.title = title
        activity.window.decorView.sendAccessibilityEvent(AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED)
    }
}

Still not working !! Does contentDescription of an ImageView has this much power?

I need to announce the title text when the page loads and if the user taps (or swipe left/right)then Imageview description needs to announce

XML ....
