I\'am using Fragment which is an instance of Fragment and not of DialogFragment.
I did google most of the search result shows how to use DialogFragment to have DateP
Use a DialogFragment
If i am guessing right you want to show a DatePicker on click of buttonDate
http://developer.android.com/guide/topics/ui/controls/pickers.html
On Button click
DialogFragment picker = new DatePickerFragment();
picker.show(getFragmentManager(), "datePicker");
DatePickerFragment.java
public 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);
}
@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("yyyy-MM-dd");
String formattedDate = sdf.format(c.getTime());
}
}
