Question

我创建了一个TimePickerDialog，在我的对话框的顶部，我看到了我设置的时间。我看到HH：mm AM但是我不想看到＆＃34; AM＆＃34;。我没有设置标题，我也不知道如何覆盖这个标题。我怎么能这样做？

 public static class TimePickerFragment extends DialogFragment implements TimePickerDialog.OnTimeSetListener{

        private TimePickerDialog timepic;
        private Calendar dateLimit;


        @Override
        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

            Calendar calendar = new GregorianCalendar();
            calendar.set(Calendar.HOUR_OF_DAY, hourOfDay);
            calendar.set(Calendar.MINUTE, minute);
            if (flag == 0) {
                calendar.set(Calendar.HOUR_OF_DAY, 0);
                calendar.set(Calendar.MINUTE, 0);
                calendar.set(Calendar.SECOND, 0);
                calendar.set(Calendar.MILLISECOND, 0);
                startDate = calendar.getTime();
//                if (endDate.getTime() < startDate.getTime())
//                    tvEndDate.setText("");
//                tvStartDate.setText(simpleDateFormat.format(startDate));
            } else if (flag == 1) {
                calendar.set(Calendar.HOUR_OF_DAY, 23);
                calendar.set(Calendar.MINUTE, 59);
                calendar.set(Calendar.SECOND, 59);
                calendar.set(Calendar.MILLISECOND, 0);
                endDate = calendar.getTime();
//                if (endDate.getTime() >= startDate.getTime())
//                    tvEndDate.setText(simpleDateFormat.format(endDate));
//                else
//                    Toast.makeText(getActivity().getApplicationContext(), "Data końcowa musi być większa od daty początkowej", Toast.LENGTH_LONG).show();
            }
        }

        @Override
        public Dialog onCreateDialog(Bundle savedInstanceState) {
            Calendar c = Calendar.getInstance();
            if (flag == 0) {
                c = DateToCalendar(startDate);
            } else if (flag == 1) {
                c = DateToCalendar(endDate);
            }
            timepic = new TimePickerDialog(getActivity(), this, c.get(Calendar.HOUR_OF_DAY), c.get(Calendar.MINUTE), true);
            return timepic;
        }
    }

TimePickerDialog是AlertDialog的子类。这意味着您可以在调用setTitle(CharSequence text)时直接使用onTimeSet方法。

Java android TimePickerDialog改变了tittle显示时间
