FCM：當應用程序處於前台狀態時處理其應用程序的不同數據通知

Question

我正在使用雲功能在我的應用程序中發送2種不同的數據通知。

當我在應用程序中收到第一條通知並點擊通知時，它會使用未決Intent重定向到我的預期頁面。

現在，當我在應用程序中收到第二條通知並點擊通知時，如何重定向到另一個活動（已發送邀請頁面）。 如何實現這一點。

這是您從服務器推送的通知中使用標記的簡單代碼段。

當您在onMessageRecevied函數中收到通知時，提取該標志並將其傳遞給sendNotification

    private void sendNotification(int flag, String title,String messageBody ) {
NotificationManager    mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    long notificatioId = System.currentTimeMillis();


Intent intent=null;
   if(flag==1){
        intent = new Intent(getApplicationContext(), activity1.class);
   }
   else{
         intent = new Intent(getApplicationContext(), activity2.class);
   }

    intent.putExtra("fromItem",false);
    intent.putExtra("title", title);; // Here pass your activity where you want to redirect.

    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
    PendingIntent contentIntent = PendingIntent.getActivity(this, (int) (Math.random() * 100), intent, 0);

    int currentapiVersion = android.os.Build.VERSION.SDK_INT;
    if (currentapiVersion >= android.os.Build.VERSION_CODES.LOLLIPOP){
        currentapiVersion = R.mipmap.ic_launcher;
    } else{
        currentapiVersion = R.mipmap.ic_launcher;
    }

    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(currentapiVersion)
            .setContentTitle(this.getResources().getString(R.string.app_name))
            .setStyle(new NotificationCompat.BigTextStyle().bigText(messageBody))
            .setContentText(title)
            .setAutoCancel(true)
            .setPriority(Notification.PRIORITY_HIGH)
            .setDefaults(Notification.FLAG_AUTO_CANCEL | Notification.DEFAULT_LIGHTS | Notification.DEFAULT_VIBRATE | Notification.DEFAULT_SOUND)
            .setContentIntent(contentIntent);
    mNotificationManager.notify((int) notificatioId, notificationBuilder.build());
}

在服務器端代碼中，將標志添加到JSON消息中

 var data = new
            {

                to=deviceId,
                    notification = new
                    {
                        body = "\""+notificationMessage +"\"",
                        title = "\""+_title+"\"",
                        sound = "Enabled\""
                    }
                    ,
                    data=new {

                        flag= "\"" + _flag+"\"",
                        message= "\""+notificationMessage+"\"",
                        additional = "\"" + addtional+"\""

                    }




            };

這是json數據包的簡單代碼段

您無法在NotificationBuilder預定義它，但是您可以做一件事，創建一個通用活動，並使用某種標記/類型將所有通知路由到該活動，以識別通知類型。 通過檢查您傳遞的通知類型，您可以從此活動重定向到所需的活動。

Answer 3

在此函數內，根據messageBody更改Intent，

private void createNotification(String messageBody, String FirstName, String amount,String docId) {

    Intent intent=null;
    if(messageBody.contains(“xyz”))
            intent = new Intent( this, ReceivedNotification.class );
    else
            intent = new Intent( this, SecondReceivedNotification.class );

    — — —

    PendingIntent resultIntent = PendingIntent.getActivity( this , 0, intent,
            PendingIntent.FLAG_UPDATE_CURRENT);
}

並將其傳遞給“待處理的意圖”。
