Android - 通知后删除感应警报

我想要做的是有一个接近警报服务，只有当您步入半径（不停止服务）时才会触发通知。我的代码会在每次进入半径内以及每次走出半径时触发通知。我一直在尝试与布尔和removeProximityAlert，但没有成功。有任何想法吗？Android - 通知后删除感应警报

做尝试也许因为它通过它已经通过不同的背景下，现在 – JRowan 2013-05-09 21:04:58

是啊，试过太 – KKO 2013-05-09 21:15:09

我读使用String键= LocationManager.KEY_PROXIMITY_ENTERING移除，而不是proximityIntent的PendingIntent; \t \t \t \t \t \t布尔输入= arg1.getBooleanExtra（key，false）;在onRecieve和使用if（进入）{}其他{}是进入和退出，我不能让它工作，虽然 – JRowan 2013-05-09 21:18:06

它触发后，您应该删除接近警报，而不是再重新创建它（节省一些标志，作为一个变量，或者，如果你使用SQLite，在你的分贝）。

删除警报是有点棘手，有2层要采取的步骤，都将产生不想要的结果（显然）“开火”：

注销您的接收器

您可以保存接收器（或接收器的阵列）和直接unregister它：

for (ProximityReceiver proximityReceiverLocal:proximityReceiverArray) { 
    context.unregisterReceiver(proximityReceiverLocal); 
    proximityReceiverArray.remove(proximityReceiverLocal); // clear pile 
}

删除警报

注意：您无法将警报另存为对象，您必须重新创建PendingIntent并将其提交至removeProximityAlert方法。挂起的意图必须具有相同的意图（即相同action name）和相同的未决意图ID：

public void removeProximityAlert(int pendingIntentIdIn, String intentActionNameIn) { 
    Intent intent = new Intent(intentActionNameIn); 
    PendingIntent pendingIntent = PendingIntent.getBroadcast(context , pendingIntentIdIn, intent, 0); 
    locationManager.removeProximityAlert(pendingIntent); 
}

如果你删除一个，而不是其他，你会达到什么您的预期目标，你什么时候出现的输入POI的半径，但是会浪费宝贵的电池寿命和内存。
