Android Dialogfragment - Get Reference To Date Picker

The Android docs tell us to implement date pickers like so, extending DialogFragment: public static class DatePickerFragment extends DialogFragment implemen

Solution 1:

http://developer.android.com/reference/android/app/DatePickerDialog.html

In onCreateDialog(Bundle savedInstanceState) you returning reference on DatePickerDialog. return new DatePickerDialog(getActivity(), this, year, month, day);

DatePickerDialog has method getDatePicker () you can use this to get DatePicker.

UPDATE

publicstaticclassDatePickerFragmentextendsDialogFragmentimplementsDatePickerDialog.OnDateSetListener {

private DatePicker mDatePicker;

@Overridepublic Dialog onCreateDialog(Bundle savedInstanceState) {
    // Use the current date as the default date in the pickerfinalCalendarc= Calendar.getInstance();
    intyear= c.get(Calendar.YEAR);
    intmonth= c.get(Calendar.MONTH);
    intday= c.get(Calendar.DAY_OF_MONTH);

    DatePickerDialogdialog=newDatePickerDialog(getActivity(), this, year, month, day);
    mDatePicker = dialog.getDatePicker();

    return dialog;
}

publicvoidonDateSet(DatePicker view, int year, int month, int day) {
    // Do something with the date chosen by the user
}

public DatePicker getDatePicker() {
    return mDatePicker
}

}

And now you can access this datePicker.

publicvoidshowDatePickerDialog(View v) {
DatePickerFragmentnewFragment=newDatePickerFragment();
newFragment.show(getSupportFragmentManager(), "datePicker");
DatePickerpicker= newFragment.getDatePicker();

}

Solution 2:

I sorted this out with the help of this StackOverflow answer:

publicvoidshowDatePickerDialog() {
    DialogFragmentnewFragment=newDatePickerFragment();
    newFragment.show(getFragmentManager(), "datePicker");
    getFragmentManager().executePendingTransactions();     // commits the show method from aboveDatePickerDialogdialog= (DatePickerDialog) newFragment.getDialog();
    DatePickerdatePicker= (DatePicker) dialog.getDatePicker();
    Datenow=newDate();
    datePicker.setMaxDate(now.getTime());
}

You need to call .executePendingTransactions()on the fragment manager to stop the dialog fragment being added asynchronously, otherwise the getDialog() method gives a null pointer exception.

I am putting it in here for anyone in the future who may have this problem.
