推荐答案

您需要两样东西：

• AlarmManager：安排您的通知在例行基地（每日，每周，..）
• 服务：启动您的通知时，AlarmManager熄灭

下面是一个基本的例子：

Here is a basic example:

在你的活动：

Intent myIntent = new Intent(this , NotifyService.class);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
PendingIntent pendingIntent = PendingIntent.getService(this, 0, myIntent, 0);

Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.SECOND, 0);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.HOUR, 0);
calendar.set(Calendar.AM_PM, Calendar.AM);
calendar.add(Calendar.DAY_OF_MONTH, 1);

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 1000*60*60*24 , pendingIntent);

这将触发报警的每天午夜（12日上午）的。你可以改变，如果你想要的。

This will trigger Alarm each day at midnight (12 am). You can change that if you want.

现在，创建一个服务 NotifyService ，并把这个code在其的onCreate（）：

Now, create a Service NotifyService and put this code in its onCreate():

@Override
public void onCreate() {
    NotificationManager mNM = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
    Notification notification = new Notification(R.drawable.notification_icon, "Notify Alarm strart", System.currentTimeMillis());
    Intent myIntent = new Intent(this , MyActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, 0);
    notification.setLatestEventInfo(this, "Notify label", "Notify text", contentIntent);
    mNM.notify(NOTIFICATION, notification);
}

这code将显示在收到报警时通知。

And this code will show the notification when the Alarm is received.

祝您好运！
