打开特定活动时通知在后台点击

Question

有在FCM（火力地堡云消息）两种类型的消息：

显示信息：这些消息只触发onMessageReceived（）回调时，你的应用程序是在前台

数据消息： 论文的消息触发，即使你的应用程序是在前台/后台onMessageReceived（）回调/时在前台接到通知遇难

我能够打开通知按特定的活动，但在通知收到背景我可以T处理通知按（它会自动启动的主要活动）

我做了一些搜索，发现：

我添加了这些意向过滤器，以我的通知活动：

<activity android:name="com.mahdi.tiger.alahedclubnewtesting.activity.News_description" 
      android:exported="true"> 
      <intent-filter> 
       <action android:name="com.mahdi.tiger.alahedclubnewtesting.activity.News_description"></action> 
       <category android:name="android.intent.category.DEFAULT"></category> 
      </intent-filter> 
     </activity> 

但它不将不起作用..

我还发现：

When your app is in the background, Android directs notification messages to the system tray. A user tap on the notification opens the app launcher by default. 

那我该怎么办？我希望在后台收到通知来处理点击并打开我的具体活动。

这是我使用的代码：

public class myFirebaseMessagingService extends FirebaseMessagingService { 

     private static final String TAG = "FirebaseMessageService"; 
     Bitmap bitmap; 

     /** 
     * Called when message is received. 
     * 
     * @param remoteMessage Object representing the message received from Firebase Cloud Messaging. 
     */ 
     @Override 
     public void onMessageReceived(RemoteMessage remoteMessage) { 
      // There are two types of messages data messages and notification messages. Data messages are handled 
      // here in onMessageReceived whether the app is in the foreground or background. Data messages are the type 
      // traditionally used with GCM. Notification messages are only received here in onMessageReceived when the app 
      // is in the foreground. When the app is in the background an automatically generated notification is displayed. 
      // When the user taps on the notification they are returned to the app. Messages containing both notification 
      // and data payloads are treated as notification messages. The Firebase console always sends notification 
      // messages. For more see: https://firebase.google.com/docs/cloud-messaging/concept-options 
      // 
      Log.d(TAG, "From: " + remoteMessage.getFrom()); 

      // Check if message contains a data payload. 
      if (remoteMessage.getData().size() > 0) { 
       Log.d(TAG, "Message data payload: " + remoteMessage.getData()); 
      } 

      // Check if message contains a notification payload. 
      if (remoteMessage.getNotification() != null) { 
       Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody()); 

       String title=remoteMessage.getNotification().getTitle(); 
       String body=remoteMessage.getNotification().getBody(); 
       String action=remoteMessage.getNotification().getClickAction(); 



       sendNotification2(title,body,action); 
      } 

      //The message which i send will have keys named [message, image, AnotherActivity] and corresponding values. 
      //You can change as per the requirement. 
      String text = remoteMessage.getData().get("title"); 
      //message will contain the Push Message 
      String message = remoteMessage.getData().get("message"); 
      //imageUri will contain URL of the image to be displayed with Notification 
      //If the key AnotherActivity has value as True then when the user taps on notification, in the app AnotherActivity will be opened. 
      //If the key AnotherActivity has value as False then when the user taps on notification, in the app MainActivity will be opened. 
      String TrueOrFlase = remoteMessage.getData().get("AnotherActivity"); 

      //To get a Bitmap image from the URL received 
      sendNotification(message, text,TrueOrFlase); 

     } 


     /** 
     * Create and show a simple notification containing the received FCM message. 
     */ 

     private void sendNotification(String messageBody,String text, String TrueOrFalse) { 
      Intent intent = new Intent(this, Slider_description.class); 
      intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
      intent.putExtra("AnotherActivity", TrueOrFalse); 
      PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent, 
        PendingIntent.FLAG_ONE_SHOT); 

      Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); 

      NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) 
        .setSmallIcon(R.mipmap.ahed_me) 
        .setContentTitle(text) 
        .setAutoCancel(true) 
        .setContentText(messageBody) 
        .setSound(defaultSoundUri) 
        .setContentIntent(pendingIntent); 

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

      notificationManager.notify(0 /* ID of notification */, notificationBuilder.build()); 
     } 
} 

注：我使用火力地堡控制台发送通知。

非常感谢。

经过一些测试，我发现这一点。

为你的有趣的部分。

有两种类型的消息数据消息和通知 消息。数据消息在onMessageReceived中处理，无论是 该应用程序在前台还是后台。数据消息是传统上与GCM一起使用的 类型。当应用处于前台时，通知消息仅在onMessageReceived中收到 。当 应用程序在后台时，自动生成的通知显示为 。当用户点击通知时，他们将返回到 该应用程序。包含通知和数据有效载荷的消息是 作为通知消息处理。 Firebase控制台始终会发送 通知消息。

如果你想在你需要发送数据报文通知完全控制。根据我的理解，您无法使用Firebase控制台执行此操作。
