FCM：当应用程序处于前台时处理android应用程序的不同数据通知

Question

我正在使用云功能在我的应用中发送 2 个不同的数据通知。

当我在应用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活动时（已发送邀请页面）。如何实现。

这里是简单的 sn-p 在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sn-p

Answer 2

在这个函数里面，根据messageBody改变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);
}

并将其传递给 Pending Intent。

您无法在NotificationBuilder 中预定义它，但您可以做一件事，您可以创建一个通用活动并将所有通知路由到此活动，并使用某些标志/类型来识别通知类型。从此活动中，您可以通过检查您传递的通知类型重定向到所需的活动。
