android - 向通知添加一个操作以再次显示通知，但稍后，就像通知的贪睡计时器一样？

Question

我的应用显示通知。我想通过 addAction 向通知添加一个操作，导致通知消失并在一小时后重新出现，但是我不想为此打开一个 Activity ，最好的情况是:用户单击操作，通知消失并且然后在一小时后重新出现，就像通知的贪睡计时器一样。

有没有办法在不打开 Activity 的情况下做到这一点？

谢谢你的帮助

Answer 1

每个通知操作都来自 PendingIntent。当然，您不想启动 Activity ，也不必这样做。

您的案例的最佳选择是创建您的 PendingIntent:

public static PendingIntent getBroadcast (Context context, int requestCode, Intent intent, int flags)

这样，每当用户点击通知时，它就会在系统上生成一个广播。然后你必须创建一个 BroadcastReceiver , 以接收此广播并使用 AlarmManager 安排另一个 PendingIntent .第二个未决 Intent 将是一个不同的广播，无论何时触发，您的 BroadcastReceiver 都可以接收并显示新的通知。

有道理吗？

只是为了澄清成一个伪例子:

• Your app have a BroadcastReceiver registered in the Manifest to receive Broadcasts of 'com.yourapp.mybroadcast'
• Notification have a com.yourapp.mybroadcast PendingIntent with extras boolean isSchedule = true and int time = 60 (60 minutes)
• The user taps the notification and this broadcast is fired and your BroadcastReceiver receives onReceive(Context context, Intent intent)
• Inside your onReceive you read isSchedule=true (meaning it have to create a new schedule and time = 60 minutes. So it uses the AlarmManager to create a new Broadcast PendingIntent with isSchedule = false; to be fired in 60 min
• The AlarmManager will call your BroadcastReceiver again in 60min but this time with isSchedule = false, so your BroadcastReceiver knows its time to show the notification again.
