How to apply a non-static fragment method from another class?

Question

Android

I'm new to android programming.
Actually, the problem is this:
There is a class inherited from a fragment, it has a non-static method. How to call this method from another class?

Answer 1

Get a pointer to a fragment instance in this other class and call this method on the instance.
The pointer can be obtained in very different ways - it all depends on your architecture. From which thread findViewByID, to the singleton.
