Java 如何在android中设置特定时间的日历

我不想加年份或月份，只想加上每天的小时、分钟和秒。 如何使用日历对象来执行此操作？ 这是我的密码

// get a Calendar object with current time
Calendar cal = Calendar.getInstance();
// add 5 minutes to the calendar object

cal.add(Calendar.HOUR, 4);
cal.add(Calendar.MINUTE, 40);




Intent i = new Intent(this, Receiver.class);
i.putExtra("alarm_message", "O'Doyle Rules!");
// In reality, you would want to have a static variable for the request code instead of 192837
PendingIntent sender = PendingIntent.getBroadcast(this, 192837, i, PendingIntent.FLAG_UPDATE_CURRENT);

// Get the AlarmManager service
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), sender);

试用

calendar.set(Calendar.HOUR_OF_DAY, 4);
calendar.set(Calendar.MINUTE, 40);
calendar.set(Calendar.SECOND, 0);

也试试这个

cal.set(2013,2,7,15,42,30);

注意：月份值为

MonthNumber-1

（

Jan为0

，

Feb为1

，依此类推）
