There is a class:

public class MyDatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener //Создадим объект календарь @Override public Dialog onCreateDialog(Bundle savedInstanceState) { Log.d(Constants.LOG_TAG, "MyDatePickerFragment - onCreateDialog - Создадим объект календарь"); // определяем текущую дату Calendar c = Calendar.getInstance(); int year = c.get(Calendar.YEAR); int month = c.get(Calendar.MONTH); int day = c.get(Calendar.DAY_OF_MONTH); // создаем DatePickerDialog и возвращаем его Dialog picker = new DatePickerDialog(getActivity(), this, year, month, day); picker.setTitle(R.string.choose_date); return picker; } @Override public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { }

I do a call like this:

public void changeDate (View view){ Log.d(Constants.LOG_TAG, "ChangeTask - changeDate - Метод изменения даты"); //вызываем диалог и заносим результат в текстВью MyDatePickerFragment dateDialog = new MyDatePickerFragment(); dateDialog.show(getFragmentManager(), "ChangeTask"); }

As I understand the second parameter in the show method is the TAG - identifier. There is a need to call the same dialogue in another Activity .

How to check where the call came from?

As I understand it somehow you need to pull out the TAG in the onDateSet method, but how?

    It can be different. If the task is reduced to the definition of which action is started - you can call getActivity() instanceof SOME_ACTIVITY_CLASS_NAME in the dialog - this is how you define activations.

    You can also pass a set of info through arguments when starting a dialog. Use Bundle and Fragment#setArguments(Bundle args) .

    If you want to call a dialog from the fragment, FragmentDialog#setTargetFragment(Fragment fr, int requestCode) will help you. More here
