fragment -> Activity / Activity -> fragment 데이터 전달 및 메소드 호출

 

 

Activity

       val bundle = Bundle()
                        bundle.putString("isEdited", "true")
// set Fragmentclass Arguments
// set Fragmentclass Arguments
                        val fragobj = Fragment()
                        fragobj.setArguments(bundle)

 

Fragment

    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        val isEdited = requireArguments().getString("isEdited")
        return inflater.inflate(R.layout.fragment_more, container, false)
    }

 

1. 프래그먼트에서 액티비티 함수 호출
to call activity function from fragment

 (activity as MainActivity).loginCheck(ScheduleFragment())

((MainActivity)getActivity()).testFunction();

 

2. 액티비티에서 프래그먼트 함수 호출
