public class TimePickerFragment extends DialogFragment implements  TimePickerDialog.OnTimeSetListener{ 

@Override 
public Dialog onCreateDialog(Bundle savedInstanceState){ 
    //Use the current time as the default values for the time picker 
    final Calendar c = Calendar.getInstance(); 
    int hour = c.get(Calendar.HOUR_OF_DAY); 
    int minute = c.get(Calendar.MINUTE); 

    //Create and return a new instance of TimePickerDialog 
    return new TimePickerDialog(getActivity(),this, hour, minute, 
      DateFormat.is24HourFormat(getActivity())); 
} 

//onTimeSet() callback method 
public void onTimeSet(TimePicker view, int hourOfDay, int minute){ 

    Log.d("Choosen Time = ","Hour : " + String.valueOf(hourOfDay) 
      + "\nMinute : " + String.valueOf(minute) + "\n");

import android.support.v4.app.DialogFragment; 

FragmentManager fm = getActivity().getSupportFragmentManager(; 
     DatePickerFragment dialog = new DatePickerFragment(); 
     dialog.show(fm, "timeFragment"); 

DatePickerFragment() muss sich von:. android.support.v4.app.DialogFragment
