[android-developers] Re: DatePicker in a fragment

The solution I came up with was to subclass DialogFragment, returning
a DatePickerDialog in onCreate()

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

return new DatePickerDialog(sContext, dateSetListener,
sDate.get(Calendar.YEAR), sDate.get(Calendar.MONTH),
sDate.get(Calendar.DAY_OF_MONTH));

}

I implement DatePickerDialog.OnDateSetListener.onDateSet() in my
DateDialogFragment.

private DatePickerDialog.OnDateSetListener dateSetListener =
new DatePickerDialog.OnDateSetListener() {

@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {

Calendar newDate = Calendar.getInstance();
newDate.set(year, monthOfYear, dayOfMonth);
//call back to the DateDialogFragment listener
sListener.dateDialogFragmentDateSet(newDate);

}
};

I also define a listener interface in my DateDialogFragment for the
calling Activity/Fragment to implement.

public interface DateDialogFragmentListener{
public void dateDialogFragmentDateSet(Calendar date);
}

As you can see above, I fire my DateDialogFragmentListener from the
DatePickerDialog's listener.

I wrote about it in more detail with entire source here:
