Is there a fragment manager transaction end event?

Question

Java

Is there any event that happens after the transaction, like adding a fragment, is over? I just need to interact with the fragment view from the activity. Of course, you can write certain methods in the activity, then call these methods in the fragment's OnViewCreated and pass the view to them. But this option does not suit me. There is also an option to make interactions with the fragment in the onStart activity, but this does not quite suit me.
