推荐答案

可以从通知中启动服务.

It is possible to start a service from a notification.

您必须使用 PendingIntent.getService 而不是 pendingIntent.getActivity.

You have to use PendingIntent.getService instead of pendingIntent.getActivity.

Intent notificationIntent = new Intent(mContext, HandleNotificationClickService.class);
PendingIntent pendingIntent = PendingIntent.getService(mContext, 0, notificationIntent, 0);

Notification notification = new Notification(icon, tickerText,System.currentTimeMillis());
notification.setLatestEventInfo(mContext,contentTitle , contentText, pendingIntent);
notification.flags = Notification.FLAG_AUTO_CANCEL | Notification.FLAG_ONGOING_EVENT;

NotificationManager notificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);

notificationManager.notify(CALLER_ID_NOTIFICATION_ID, notification);
