如何添加fcm通知？

Question

如何在應用程序處於後臺時在收件箱樣式中添加fcm通知？

當我添加了下面的代碼，我得到的收件箱風格，當應用程序是開放

但如果應用程序是背景，顯示單獨的通知

public class MyFirebaseMessagingService extends FirebaseMessagingService { 

    private static final String TAG = "MyFirebaseMsgService"; 

    Integer notify_no = 0; 

    Integer numMessages = 0; 

    DBHelper db = new DBHelper(this); 

    private final int notificationID = 237; 
    private static int value = 0; 
    // Notification.InboxStyle inboxStyle = new Notification.InboxStyle(); 
    //Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.newlogo); 


     // TODO(developer): Handle FCM messages here. 

     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()); 
      /* Integer badge = Integer.parseInt(remoteMessage.getData().get("badge")); 
      Log.d("notificationNUmber",":"+badge); 
      setBadge(getApplicationContext(), badge);*/ 
     } 

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



     Intent intent = new Intent(); 
     intent.setAction("com.ksoft.propreka.CUSTOM_INTENT"); 
     sendBroadcast(intent); 

     db.insertNotification(remoteMessage.getNotification().getBody(),remoteMessage.getData().get("room_id")); 

     //EventBus.getDefault().post(remoteMessage.getNotification().getBody()); 
     // 

     try { 
      if (remoteMessage.getNotification() != null) { 
       sendNotification(remoteMessage.getData().get("text")); 
      } else if (!remoteMessage.getData().isEmpty()) { 
       sendNotification(remoteMessage.getData().get("text")); 
      } 
     } catch (Exception e) { 
      Log.d("json error", e.toString()); 
     } 

     //sendNotification(remoteMessage.getData().get("text")); 
     Log.d("test",":test notification"); 
     //createpushnotification(); 

     // Also if you intend on generating your own notifications as a result of a received FCM 
     // message, here is where that should be initiated. See sendNotification method below.

Answer 1

使用數據有效載荷發送通知數據，並使用這個類表現出來的手機。

例如：

隨着通知有效載荷

{ 
    "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...", 
    "notification" : { 
     "body" : "great match!", 
     "title" : "Portugal vs. Denmark", 
     "icon" : "myicon" 
    } 
    } 

此數據將被火力顯示到手機默認通知時，應用程序是在背景但從FirebaseMessagingService的onMessageReceived方法將被調用當應用程序在前臺。

隨着數據有效載荷

每次你發送通知onMessageReceived方法將被調用。所以你可以建立你想要的通知。

{ 
    "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...", 
    "data" : { 
    "Nick" : "Mario", 
    "body" : "great match!", 
    "Room" : "PortugalVSDenmark" 
    }, 
}

有兩種類型的FCM消息。

• 通知消息。
• 數據信息。

FCM

發送數據信息，那麼它會在您的通話方式。

當在後臺應用時，FCM不會調用onMessageReceived方法。 而不是顯示默認通知。
