Can getContext() be null in this flow?

If I have an onClickListener that is called when user clicks on a button and that listener does a callback to a method of the containing fragment which does getContext().
Is there a case that the getContext() in this sequence could return null?
I am trying to understanding if doing Context c = getContext(); if(c == null) return; makes sense in this specific case/flow or is a useless defensive check

Update for the referred links in the comments:
I understand that when we access the context via a callback it can be null e.g. when handling a network request.
But a callback that is called when the user did an interaction with a UI element as in the case I describe is there a situation that can be null.
Flow is:

User clicks a button
Action listener is called and calls another callback
The callback listener inside the containing fragment does getContext()

Can this flow ever end up with getContext() returning null?

@nyulan: Very useful but the flow I describe is very specific and not if in general it can ever be `null` – Jim Aug 29 '18 at 08:31

are you inside a fragment or an activity? if fragment then call using getActivity() and if activity then call using (Activity Name).this or this or getContext(). – ChandraShekhar Kaushik Jul 08 '19 at 09:44
