android - 通知未在 android 中启动 Activity

Question

我正在开发一个小应用程序，我希望后台服务在其中发送通知，当用户单击通知时，它必须启动相应的 Activity 。我在这里发布通知代码，我的问题是通知显示在状态栏上，但是当我单击它时它不会启动 Activity 。有人可以建议我哪里出错了。请帮忙。

NotificationManager notificationManager = (NotificationManager) 
        getSystemService(NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.ic_launcher,
        "A New Message!", System.currentTimeMillis());
Intent notificationIntent = new Intent(NotificationService.this,
        com.jeris.android.MetroActivity.class);
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent pendingIntent = PendingIntent
        .getService(NotificationService.this, 0, notificationIntent,
                PendingIntent.FLAG_UPDATE_CURRENT | PendingIntent.FLAG_ONE_SHOT);
notification.setLatestEventInfo(NotificationService.this, "Bullion",
        "Rates for "+ parsedDate+"has not been updated. Go to app to check rates",
        pendingIntent);
notificationManager.notify(11, notification);

Answer 1

替换PendingIntent.getService(NotificationService.this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT | PendingIntent.FLAG_ONE_SHOT);

与PendingIntent.getActivity(NotificationService.this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT | PendingIntent.FLAG_ONE_SHOT);

注意 getService 被替换为 getActivity。
