Answer 1

在 showTime() 方法中设置日历中的时间如下:

public void showTime() {
    if(flag == true) {

        Calendar calender = Calendar.getInstance();
        myTimePicker = new TimePickerDialog(this, new OnTimeSetListener() {

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


                Calendar newTime = Calendar.getInstance();

                //newTime.set(hourOfDay, minute); // remove this line

                //Add these two line
                newTime.set(Calendar.HOUR_OF_DAY, hourOfDay);
                newTime.set(Calendar.MINUTE, minute);

                GotTime = GotDate + " At " + String.valueOf(hourOfDay) + " :" + String.valueOf(minute + 1);
                time.setText(GotTime);
            }
        }, calender.get((Calendar.HOUR_OF_DAY)), calender.get(Calendar.MINUTE), true);
    }

    }

编辑:要在上午/下午获得 HourOdDay，您可以执行以下操作:

String format = "hh:mm a"; // your own format
 SimpleDateFormat sdf = new SimpleDateFormat(format, Locale.US);
 String formated_time = sdf.format(newTime.getTime());  
 //formated_time would show you time like "hh:mm am/pm".
