Access fragment methods and events

Hello everyone, it’s possible to access the methods and events of the fragment from the screen where it is invoked. In other words, if I have an event programmed in a button and I need to rewrite it or return your response to know it from the main screen. I’m designing a survey form, the questions and answers change depending on the client’s profile, so it is something dynamic, but there are steps within the survey that require me to show or not other fragments and I do not know how to interact with other fragments depending on the that a previous fragment has in information or answers.

Thank you very much for any help or ideas.
