单击通知构建器

Question

我想知道用户何时点击通知，我在我的服务中添加以下代码

RemoteViews remoteviews = new RemoteViews("com.eample.triplogger", R.layout.custom_notifications);

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(GcmIntentService.this)
              .setContent(remoteviews)
               .setSmallIcon(R.drawable.ic_launcher)
               .setContentTitle("My notification")
               .setContentText("Hello World!")
               .setOngoing(true);
PendingIntent  contentIntent = PendingIntent.getActivity(this, PENDING_TRIPS_NOTIFICATION_ID,
               new Intent(this, MainActivity.class).putExtra("is_log", true), Intent.FLAG_ACTIVITY_CLEAR_TOP);
remoteviews.setOnClickPendingIntent(R.layout.custom_notifications, contentIntent);

    mBuilder.setContentIntent(contentIntent);//click on whole notification action
                mNotificationManager.notify(PENDING_TRIPS_NOTIFICATION_ID, mBuilder.build());

当用户点击notifficaion时，我的主要活动是打开的，但是我希望得到当用户点击通知时会调用的那部分代码（如在seOnclickListener（）的情况下调用onClick（View v），同样在这里哪个回调将调用setOnClickPendingIntent（）。
