为什么我不能从DialogFragment到Fragment接收数据？

Question

我正在尝试将数据从DialogFraank发送到创建此对话框的Fraank。在目标片段中，我使用以下代码：

val noteData = NoteData()
val bundle = Bundle()
noteData.setTargetFragment(this,0)
noteData.show(fragmentManager!!, noteData.TAG)

我还在fragment实现了我的接口：

class NotepadScr : Fragment(), NotesInterface

在DialogFragment中，我使用以下代码：

private var notesInterface: NotesInterface? = null
 override fun onAttach(context: Context) {
        super.onAttach(context)

        if (context is NotesInterface) {
            notesInterface = context
        } else if (parentFragment is NotesInterface) {
            notesInterface = parentFragment as NotesInterface
        }
    }

并发送数据：

notesInterface.archiveNote(recordID!!)

我还试图从这个问题中使用onActivityResult（）：

val i = Intent()
i.putExtra("selectedDate", 1122)
targetFragment!!.onActivityResult(1, Activity.RESULT_OK, i)

接收数据：

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        when(requestCode){
            1->{
                if (resultCode == Activity.RESULT_OK) {
                    // here the part where I get my selected date from the saved variable in the intent and the displaying it.
                    val bundle = data!!.extras
                    val resultDate = bundle!!.getInt("selectedDate")
                    Timber.i("****************************   %s", resultDate.toString())
                }
            }
        }
    }

但我没有收到数据：(((

Answer 1

数据必须按如下所示发送：

ReceivingFragment receivingFragment = new ReceivingFragment
Bundle bundle = new Bundle()
bundle.putString(KEY, value to be sent);//Use Int if you want to send int value
receivingFragment.setArguments(bundle);

这必须在接收碎片时完成

String receivingData = getArguments.getString(KEY);

确保KEY在发送片段和接收片段中相同。
