android - FCM : Handling different data notification of an android app when app is in foreground

Question

我在我的应用程序中使用云功能发送 2 个不同的数据通知。

当我在应用程序中收到第一个通知并点击通知时，它会使用 pendingIntent 重定向到我想要的页面。

现在，当我在应用程序中收到第二个通知并点击通知如何重定向到另一个 Activity (已发送邀请页面)时。如何实现。

这是简单的 fragment 在您从服务器推送的通知中使用标志。

当您在 onMessageRecevied 函数中收到通知时，提取该标志并将其传递给 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());
}

在服务器端代码中，在 JSON 消息中添加标志

 var data = new
            {

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

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

                    }




            };

这是json数据包的简单 fragment
