AlarmReceiver 中的 Android 通知

我希望能够创建一个警报，每 2 分钟向用户发出一次启动应用程序的通知。一切正常，但当我手动启动应用程序时会出现通知。这是我的代码：

接收器：

public void onReceive(Context context, Intent intent) {
    nm = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
    CharSequence from = "myactivity";
    CharSequence message = "click to start activity";


    Intent scheduledIntent = new Intent(context, AmslerTestActivity.class);


    PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
            scheduledIntent, 0);
    Notification notif = new Notification(R.drawable.icon,
            message, System.currentTimeMillis());
    notif.setLatestEventInfo(context, from, message, contentIntent);
    notif.flags = Notification.FLAG_AUTO_CANCEL;
    notif.defaults |= Notification.DEFAULT_SOUND;
    nm.notify(1, notif);
    scheduledIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    context.startActivity(scheduledIntent);

}

调度程序：

cal.set(Calendar.HOUR_OF_DAY, 12);
    cal.set(Calendar.MINUTE, 01);
    cal.set(Calendar.SECOND, 0);

    Intent intent = new Intent(myactivity.this, AlarmReceiver.class);

    PendingIntent sender = PendingIntent.getBroadcast(this, 0, intent,
            PendingIntent.FLAG_CANCEL_CURRENT);

    // Get the AlarmManager service
    am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    am.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), 2 * 60 * 1000, sender);

我希望通知仅在代码未运行时响起。

原文

I want to be able to create an alarm to ring a notification to the user to start the application every 2 minutes. Everything works fine, but the notification appears when i start my application manually. Here are my code :

Receiver:

public void onReceive(Context context, Intent intent) {
    nm = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
    CharSequence from = "myactivity";
    CharSequence message = "click to start activity";


    Intent scheduledIntent = new Intent(context, AmslerTestActivity.class);


    PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
            scheduledIntent, 0);
    Notification notif = new Notification(R.drawable.icon,
            message, System.currentTimeMillis());
    notif.setLatestEventInfo(context, from, message, contentIntent);
    notif.flags = Notification.FLAG_AUTO_CANCEL;
    notif.defaults |= Notification.DEFAULT_SOUND;
    nm.notify(1, notif);
    scheduledIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    context.startActivity(scheduledIntent);

}

Scheduler:

cal.set(Calendar.HOUR_OF_DAY, 12);
    cal.set(Calendar.MINUTE, 01);
    cal.set(Calendar.SECOND, 0);

    Intent intent = new Intent(myactivity.this, AlarmReceiver.class);

    PendingIntent sender = PendingIntent.getBroadcast(this, 0, intent,
            PendingIntent.FLAG_CANCEL_CURRENT);

    // Get the AlarmManager service
    am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    am.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), 2 * 60 * 1000, sender);

I want the notification to only ring when the code is not running.

将代码的“调度程序”部分放入 onPause、onStop 或 onDestroy 中，以便仅在 Activity< 一次时设置闹钟/code> 停止。请阅读此处来决定哪个最适合您的目的。然后，在执行am.setRepeating时，对triggerAtTime使用System.currentTimeMillis() + 2 * 60 * 1000，使闹钟触发2从 Activity 停止的时间算起的分钟数。然后，它将根据第三个参数“间隔”每 2 分钟重复一次，您当前已将其正确设置为 2 分钟。
