Have you tried onContentChanged() yet?
The documentation says
This hook is called whenever the content view of the screen changes (due to a call to Window.setContentView or Window.addContentView).
Question
is there a listener or some way to determine when contentView is created? I have used other type listeners and they work for other child views inside of content view. however content view is different. I have not yet found anything that works.
