fragment - custom dialog click Listener 구현 / fragment에서 supportFragmentManager

Fragment

 
private var myContext: FragmentActivity? = null
override fun onAttach(activity: Activity) {
    myContext = activity as FragmentActivity
    super.onAttach(activity)
}
 
 
 override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
 ....
 
        view.reservation_cancel_tv_reservation.setOnClickListener { content ->
//fragment manager - supportFragmentManager 구현

            var fragManager: FragmentManager = myContext!!.supportFragmentManager
            val dialog = DeleteDialog()
            // 버튼 클릭 이벤트 설정
            dialog.setButtonClickListener(object : DeleteDialog.OnButtonClickListener {
                override fun onButtonYesClicked() {

                    Log.d("Test", "DeleteDialog - 삭제 btn 클릭 Listen / Bottom에서 확인")
                    //삭제 레트로핏 구현
                    dismiss()
                }

                override fun onButtonCloseClicked() {
                    dismiss()
                }

                override fun onButtonCancelClicked() {
                    dismiss()
                }
            })
            dialog.show(fragManager, "CustomDialog")
        }

 

           var fragManager: FragmentManager = myContext!!.supportFragmentManager

fragManager 변수를 지정해서 사용. 

 

 

 

dialog

class DeleteDialog : DialogFragment() {
    private var _binding: DialogOngoingRvCancelBinding? = null
    private val binding get() = _binding!!

    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        _binding = DialogOngoingRvCancelBinding.inflate(inflater, container, false)
        val view = binding.root
        // 레이아웃 배경을 투명하게 해줌, 필수 아님
        dialog?.window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))

        binding.ongoingRvCancelDialogYes.setOnClickListener {

            buttonClickListener.onButtonYesClicked()
            dismiss()    // 대화상자를 닫는 함수
        }
        binding.ongoingRvCancelDialogIvClose.setOnClickListener {
            buttonClickListener.onButtonCloseClicked()
            dismiss()
        }
        binding.ongoingRvCancelDialogNo.setOnClickListener {
            buttonClickListener.onButtonCancelClicked()
            dismiss()
        }

        return view
    }

    override fun onDestroyView() {
        super.onDestroyView()
        _binding = null
    }

    // 인터페이스
    interface OnButtonClickListener {
        fun onButtonYesClicked()
        fun onButtonCloseClicked()
        fun onButtonCancelClicked()
    }
    // 클릭 이벤트 설정
    fun setButtonClickListener(buttonClickListener: OnButtonClickListener) {
        this.buttonClickListener = buttonClickListener
    }
    // 클릭 이벤트 실행
    private lateinit var buttonClickListener: OnButtonClickListener


}
