FCM通知onclick未打开所需的活动

Question

我已经尝试了几乎每一个解决方案张贴在这里和每一个标志的组合，但它是不工作的。

当我在RateEventActivity场景中单击来自后台模式的通知时，意图丢失在某个地方（未在创建时传递给MainActivty)。

我也尝试传递唯一的id到我的待定意图，但没有运气。我花了很多时间和精力来解决这个问题，但每次都失败了

这是我的FCM代码

  private void createNotification(RemoteMessage remoteMessage) {
    RemoteMessage.Notification notification = remoteMessage.getNotification();
    NotificationManager mNotificationManager = (NotificationManager)
            this.getSystemService(Context.NOTIFICATION_SERVICE);

    Log.v("Notification Title", remoteMessage.getNotification().getTitle());

    Intent intent = new Intent(this, MainActivity.class);
    //intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
    if (remoteMessage.getData().containsKey("notificationUser")) {
        intent.putExtra("notificationUser", remoteMessage.getData().get("notificationUser"));
    } else if (remoteMessage.getData().containsKey("notificationId")) {
        intent.putExtra("notificationId", remoteMessage.getData().get("notificationId"));
    } else if (remoteMessage.getData().containsKey("event")) {
        if (remoteMessage.getNotification().getTitle().equalsIgnoreCase("Event Feedback")) {


            Log.v("Notification Event", remoteMessage.getData().get("event"));
            intent.putExtra("eventId", remoteMessage.getData().get("event"));
        }


    }


    //PendingIntent.FLAG_UPDATE_CURRENT
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0 , intent,
            PendingIntent.FLAG_UPDATE_CURRENT);

    Bitmap largeIcon = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);

    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.drawable.ic_notification)
                    .setLargeIcon(largeIcon)
                    .setContentTitle(notification.getTitle())
                    .setStyle(new NotificationCompat.BigTextStyle()
                            .bigText(notification.getBody()))
                    .setContentText(notification.getBody())
                    .setAutoCancel(true);

    mBuilder.setContentIntent(contentIntent);
    mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}

   if (getIntent().hasExtra("notificationId")) {
        Intent intent = new Intent(this, NotificationActivity.class);
        intent.putExtra("notificationId", getIntent().getStringExtra("notificationId"));
        startActivity(intent);
    } else if (getIntent().hasExtra("user")) {
        Intent intent = new Intent(this, ProfileActivity.class);
        intent.putExtra("userId", getIntent().getStringExtra("user"));
        startActivity(intent);
    } else if (getIntent().hasExtra("eventId")) {
        Intent intent = new Intent(this, RateEventActivity.class);
        intent.putExtra("eventId", getIntent().getStringExtra("eventId"));
        startActivity(intent);
    }

我的清单文件

        android:name=".activities.MainActivity"
        android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
        android:launchMode="singleTop"
        android:screenOrientation="portrait"
        android:theme="@style/HomeTheme" />

如果你想打开你的应用程序并执行一个特定的动作[在后台]，在通知负载中设置click_action，并将它映射到你想要启动的活动中的一个意图过滤器。例如，将click_action设置为OPEN_ACTIVITY_1以触发如下所示的意图筛选器：

正如react-native-fcm文档中所建议的,要求后端以如下形式发送json数据,

 {

    "to":"some_device_token",

    "content_available": true, 
    "notification": {
    "title": "hello",
    "body": "yo",
    "click_action": "OPEN_ACTIVITY_1" // for intent filter in your activity
    },

"data": {
"extra":"juice"
}
}

并在mainfest文件中为您的活动添加intent-filter，如下所示

<intent-filter>
  <action android:name="OPEN_ACTIVITY_1" />
  <category android:name="android.intent.category.DEFAULT" />
</intent-filter>

Bundle b = getIntent().getExtras();// add these lines of code to get data from notification
String someData = b.getString("someData");
