[英]cancel Service when user clicks Notification
Similar to this post I got a service that does some work in the background. 与这篇文章类似,我得到了一项在后台执行某些工作的服务。 When the service starts, I'm displaying a notification. 服务启动时,我正在显示通知。 Usually you can assing an intent to the notification that is triggered when the user clicks onto the notification. 通常,您可以为用户单击通知时触发的通知添加意图。 Mostly an activity is then started. 然后通常会开始一项活动。
But how can I use a notification to inform the background service that the user want's to cancel its operation? 但是,如何使用通知来通知后台服务用户希望取消其操作?
You can have a BroadcastReceiver to stop the Service, which is triggered through the PendingIntent of the Notification. 您可以有一个BroadcastReceiver来停止服务,该服务是通过通知的PendingIntent触发的。
Have a look at the PendingIntent.getBroadcast(...) and use it instead of the PendingIntent.getActivity()
method. 看一下PendingIntent.getBroadcast(...)并使用它代替PendingIntent.getActivity()
方法。 You can use it like this: 您可以像这样使用它:
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);
The BroadcastReceiver could be an inner class in your Service to simply call stopService()
in the onReceive()
method. BroadcastReceiver可以是您Service中的一个内部类,以仅在onReceive()
方法中调用stopService()
。
