我正在尝试使用报警管理器在特定时间向用户发送通知.基本上,什么也没有发生,对我来说代码看起来不错.我的Alarm Manager的代码如下：

/** Notify the user when they have a task */

public void notifyAtTime() {

Intent myIntent = new Intent(PlanActivity.this,Notification.class);

AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);

PendingIntent pendingIntent = PendingIntent.getService(PlanActivity.this,myIntent,0);

Calendar calendar = Calendar.getInstance();

calendar.set(Calendar.HOUR_OF_DAY,12);

calendar.set(Calendar.MINUTE,17);

calendar.set(Calendar.SECOND,00);

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

}

“通知”类中的通知代码如下：

public class Notification extends Service {

@Override

public void onCreate() {

Toast.makeText(this,"Notification",Toast.LENGTH_LONG).show();

Intent intent = new Intent(this,PlanActivity.class);

PendingIntent pending = PendingIntent.getActivity(this,intent,0);

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(

this).setSmallIcon(R.drawable.ic_launcher)

.setContentTitle("Football")

.setContentText("Don't forget that you have Football planned!")

.setContentIntent(pending);

NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

manager.notify(0,mBuilder.build());

}

@Override

public IBinder onBind(Intent intent) {

// TODO Auto-generated method stub

return null;

}

}

在Notification类中设置的Toast也不会出现.我不知道这是真的很傻,我失踪了,但任何帮助将不胜感激！
