Question

timepickerdialog screenshot1 2我只需要从timepicker对话框中获取开始时间和结束时间，并使用开始时间和结束时间值设置TextView，但是我有相同的开始时间和结束时间值，因为我可以不能从timepicker中获取开始时间的值，当我单击完成时，它会同时分配timepicker的最后一个值，这很有意义。顺便说一句，如果有不好的代码实现，我真的很抱歉。谢谢您的帮助。

private int openingHour = 0;
private int openingMinute = 0;
private int closingHour = 0;
private int closingMinute = 0;
private void setWorkingHoursTextView() {
    // TODO Auto-generated method stub
    Calendar mCurrentTime = Calendar.getInstance();
    int initialHour = mCurrentTime.get(Calendar.HOUR_OF_DAY);
    int initialMinute = mCurrentTime.get(Calendar.MINUTE);
    TimePickerDialog mTimePickerDialog = new TimePickerDialog(getContext(), new TimePickerDialog.OnTimeSetListener() {
        @Override
        public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                        openingHour = timePicker.getHour();
                        openingMinute = timePicker.getMinute();
                   if (openingHour != 0) {
                        closingHour = timePicker.getHour();
                        closingMinute = timePicker.getMinute();

在TimePickerDialog上，有变量selectedHour和selectedMinute。您可以使用它来检索所选内容的值。代码应该是这样的

TimePickerDialog mTimePickerDialog = new TimePickerDialog(getContext(), new TimePickerDialog.OnTimeSetListener() {
        @Override
        public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
            if (openingHour != 0) {
                closingHour = selectedHour;
                closingMinute = selectedMinute;
            }
            else {
                openingHour = selectedHour;
                openingMinute = selectedMinute;
            }
            workingHoursTextView.setText(
                    openingHour + ":" + openingMinute + "-" + closingHour + ":" + closingMinute);
        }
    }, initialHour, initialMinute, true);//Yes 24 hour time

如何从一个时间获取小时和分钟PickerDialog两次以获取开始时间和结束时间
