问题描述

我正在使用 Firebase 云消息传递 API 创建应用程序...我能够从服务器向我的客户端应用程序发送通知和数据.但问题是当应用程序打开时，数据出现时通知没有触发(我的意思是我记录了它)这不是问题.但是当应用程序关闭时，会收到通知，当我单击通知时，活动已打开，而我看不到日志数据.我需要将数据更新到 TextView..

I am Creating an App using Firebase cloud messaging API... I am able to send notification and data to my client application from the server. But the problem is When the application is open the notification is not firing while the data appears (I Mean I logged it) It is not an issue. But when the application is closed, the notification is received, while I clicked on notification the activity is opened while I am not able to see the log data. I need to Update the data to a TextView..

我的 MyFirebaseMessagingService :

My MyFirebaseMessagingService :

public void onMessageReceived(RemoteMessage remoteMessage) {
        // TODO: Handle FCM messages here.
        // If the application is in the foreground handle both data and notification messages here.
        // Also if you intend on generating your own notifications as a result of a received FCM
        // message, here is where that should be initiated.
        Log.d(TAG, "From: " + remoteMessage.getFrom());
        Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
        Log.e("FROM", "From: " + remoteMessage.getFrom());
        String data = remoteMessage.getData().get("message");
        Log.e("KOIII", "Notification Message Body: " + remoteMessage.getNotification().getBody());
       // showNotificationS(remoteMessage.getNotification().getBody(),2);
        if(data.equals("true")){
            Log.e("DATA", "SUCCESS");
           // Fragment1.getInstace().updateTheTextView(data, data, data);
        }
    }

我的清单:

<activity
            android:name=".SplashScreen"
            android:label="@string/app_name"
            android:launchMode="singleInstance">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".myHome"
            android:label="@string/app_name">
        </activity>
<service android:name=".MyFirebaseMessagingService">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT"/>
            </intent-filter>
        </service>
        <service android:name=".FirebaseIDService">
            <intent-filter>
                <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
            </intent-filter>
        </service>

推荐答案

如果您的应用在前台，FCM 将不会显示通知，因此您手动显示如下:-

FCM will not show notification if your app is in foreground, So you have manually show that like this:-

@Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        // TODO(developer): Handle FCM messages here.
        // If the application is in the foreground handle both data and notification messages here.
        // 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.
        Log.d(TAG, "From: " + remoteMessage.getFrom());
        Log.d(TAG, "From: " + remoteMessage.getData().get("message"));
//        Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
        sendNotification(remoteMessage.getData().get("message"));
    }
    // [END receive_message]

    /**
     * Create and show a simple notification containing the received FCM message.
     *
     * @param messageBody FCM message body received.
     */
    private void sendNotification(String messageBody) {
        Intent intent = new Intent(this, MarketActivity.class);
//        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        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.drawable.ic_launcher)
                .setContentTitle("Fred Notification")
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
                .setContentIntent(pendingIntent);

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

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