public class TimePickerFragment extends DialogFragment implements TimePickerDialog.OnTimeSetListener {
    int hour, minute;

    public Dialog onCreateDialog(Bundle savedInstanceState) {
        return new TimePickerDialog(getActivity(), this, hour, minute, false);//返回一个TimePickerDialog
    }

    @Override
    public void onTimeSet(TimePicker view, int hourOfDay, int minuteOfHour) {
        hour = hourOfDay;
        minute = minuteOfHour;
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("hh:mm aa");
        Date date;
        Calendar calendar = Calendar.getInstance();//Date构造方法过时，Calendar转Date
        calendar.set(0,0,0,hour,minute);
        date = calendar.getTime();
        String strDate = simpleDateFormat.format(date);

        Toast.makeText(getActivity(), "you have selected" + strDate,
                Toast.LENGTH_SHORT).show();
    }
}
