You have two options for Java and Kotlin. However, logic of both ways are same. You should call activity after call finish() method.

Answer_1: activity!!.finish()
Answer_2: activity?.finish()

getActivity().finish();

When working with fragments, instead of using this or refering to the context, always use getActivity(). You should call

getActivity().finish();

to finish your activity from fragment.
