Answer1: Values don't differ in my case, I am using DialogFragment here is my code:
public static class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {
@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);
}
public void onDateSet(DatePicker view, int year, int month, int day) {
// Do something with the date chosen by the user
Log.v(TAG, "Year: " + year + " ,Month: "+ month + " ,Day: " + day );
}
}
and this is the result: Year: 2014 ,Month: 1 ,Day: 25
the values are same for three versions of Android, ( 4.1.1, 4.4.2, 2.3.3 ) which I tested.
