推荐答案

你需要做两件事:

• AlarmManager:定期(每天、每周……)安排您的通知.
• 服务:在 AlarmManager 关闭时启动通知.

这是一个基本示例:

在您的活动中:

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);

这将在每天午夜(凌晨 12 点)触发警报.如果你愿意，你可以改变它.

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 并将此代码放入其 onCreate() 中:

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);
}

此代码将在收到警报时显示通知.

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

祝你好运！
