取消服务，当用户点击通知 [英] cancel Service when user clicks Notification

问题描述

类似<一个href=\"http://stackoverflow.com/questions/20501225/using-service-to-run-background-and-create-notification\">this帖子我得到了确实在后台的一些工作的服务。在服务启动时，我展示的通知。通常你可以assing的意图，当用户点击到的通知所触发的通知。大多是一个活动，然后启动。

Similar to this post I got a service that does some work in the background. When the service starts, I'm displaying a notification. Usually you can assing an intent to the notification that is triggered when the user clicks onto the notification. Mostly an activity is then started.

但我怎么可以用一个通知，告知用户想要的取消其操作的后台服务？

But how can I use a notification to inform the background service that the user want's to cancel its operation?

推荐答案

您可以有一个BroadcastReceiver停止服务，这是通过通知的触发的PendingIntent

You can have a BroadcastReceiver to stop the Service, which is triggered through the PendingIntent of the Notification.

有一个看的 PendingIntent.getBroadcast（...），并用它代替 PendingIntent.getActivity（）的方法。您可以使用它是这样的：

Have a look at the PendingIntent.getBroadcast(...) and use it instead of the PendingIntent.getActivity() method. You can use it like this:

  Intent broadcastIntent = new Intent(context, YourBroadcastReceiver.class);      
  PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, broadcastIntent, 0);
  Notification noti = new Notification.Builder(this)
         ...
         .setContent(pendingIntent);
         .build();

  notification.setContent(pendingIntent);

该广播接收器可能是一个内部类中为您服务，只需拨打 stopService（）在的onReceive（）方法。
