AlarmManager在特定的日期和时间(AlarmManager at specific dat

2019-08-04 13:15发布

我想显示在特定日期和时间(25/12/2012 12.00),我使用此代码的对话框。 我喜欢设置11个月(因为0是根),但报警器不启动。 什么是我的错?

Calendar cal=Calendar.getInstance();
    cal.set(Calendar.MONTH,11);
    cal.set(Calendar.YEAR,2012);
    cal.set(Calendar.DAY_OF_MONTH,25);
    cal.set(Calendar.HOUR_OF_DAY,12);
    cal.set(Calendar.MINUTE,00);
    cal.set(Calendar.SECOND,0);

Intent _myIntent = new Intent(context, Notify.class);
    PendingIntent _myPendingIntent = PendingIntent.getBroadcast(context, 123, _myIntent, PendingIntent.FLAG_UPDATE_CURRENT|  Intent.FILL_IN_DATA);

AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), _myPendingIntent);  

Answer 1:

看看下面的代码对我是多么要设置为12月当月报警:

// for Alarm 25/12/2012 at 12.00   
Calendar myAlarmDate = Calendar.getInstance();
myAlarmDate.setTimeInMillis(System.currentTimeMillis());
myAlarmDate.set(2012, 11, 25, 12, 00, 0);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);

Intent _myIntent = new Intent(context, AlarmReceiverNotificationForEveryMonth.class);
_myIntent.putExtra("MyMessage","HERE I AM PASSING THEPERTICULAR MESSAGE WHICH SHOULD BE SHOW ON RECEIVER OF ALARM");
PendingIntent _myPendingIntent = PendingIntent.getBroadcast(context, 123, _myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager.set(AlarmManager.RTC_WAKEUP, myAlarmDate.getTimeInMillis(),_myPendingIntent);

您可以更新您的意图和类上面的代码,你会得到你的愿望输出。

希望这帮助你。
