Updated code

FragmentFile

public class FirstFragment extends Fragment implements DatePickerDialogFragmentEvents{
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_first, container, false);
        EditText editText = (EditText) view.findViewById(R.id.visitDateFiled);

        editText.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                DialogFragment picker = new DatePickerFragment();
                picker.setDatePickerDialogFragmentEvents(FirstFragment.this); //Changed
                picker.show(getFragmentManager(), "Date Picker");
            }
        });
        return view;
    }

    //This is where you will get selected date value
    @Override
    public void onDateSelected(String date) {
        String selectedDate = date;
    } 
 }

DialogFragment

public class DatePickerFragment extends DialogFragment
        implements DatePickerDialog.OnDateSetListener {

    //Interface created for communicating this dialog fragment events to called fragment
    public interface DatePickerDialogFragmentEvents{
       void onDateSelected(String date);
    }

    DatePickerDialogFragmentEvents dpdfe

    public void setDatePickerDialogFragmentEvents(DatePickerDialogFragmentEvents dpdfe){
         this.dpdfe = dpdfe;
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the current date as the default date in the picker
        final Calendar c = Calendar.getInstance();
        int year = c.get(Calendar.YEAR);
        int month = c.get(Calendar.MONTH);
        int day = c.get(Calendar.DAY_OF_MONTH);
        // Create a new instance of DatePickerDialog and return it
        return new DatePickerDialog(getActivity(), this, year, month, day);
    }

    @Override
    public void onDateSet(DatePicker view, int year, int month, int day) {
        Calendar c = Calendar.getInstance();
        c.set(year, month, day);

        SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");
        String formattedDate = sdf.format(c.getTime());
        dpdfe.onDateSelected(formattedDate); //Changed
    }
}

So i created an interface named DatePickerDialogFragmentEvents in your dialogfragment class and implemented that in caller fragment. From caller fragment when you create a instance of dialogfragment, set DatePickerDialogFragmentEvents instance of fragment by using setDatePickerDialogFragmentEvents method of dialog fragment class.
