Android:通过ContentIntent传输数据 [英] Android: Transferring Data via ContentIntent

问题描述

我的Android应用程序出现问题.它通过Google Cloud Messaging接收消息，并在通知栏中显示通知.我想通过通知传输一些数据.此数据来自Google Cloud Messaging，应附加到通知中.

I've got a problem with my Android Application. It receives Messages via Google Cloud Messaging and displays a Notification in the Notificationbar. I want to transfer some Data with the Notification. This Data comes via Google Cloud Messaging and should be attached to the Notification.

这是我显示通知的代码:

This is my Code to Display the Notification:

private void setNotification(String strTitle, String strMessage, int intPageId, int intCategorieId)
    {
        notificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);

        Intent intentOpen = new Intent(this, NotificationClick.class);
        intentOpen.putExtra("pageId", Integer.toString(intPageId));
        intentOpen.putExtra("categorieId", Integer.toString(intCategorieId));
        intentOpen.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);

        PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intentOpen, 0);


        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.launcher_icon)
                .setTicker(strTitle)
                .setContentTitle(strTitle)
                .setStyle(new NotificationCompat.BigTextStyle().bigText(strMessage))
                .setContentText(strMessage);


        notificationBuilder.setContentIntent(contentIntent);
        notificationBuilder.setDefaults(Notification.DEFAULT_ALL);
        notificationManager.notify(intCategorieId, notificationBuilder.build());

    }

然后我的代码在另一个Activity(通过单击通知打开女巫打开)中获取变量"intPageId"和"intCategorieId"，是这样的:

And my Code to get the Variables "intPageId" and "intCategorieId" in a other Activity(witch opens by clicking the Notification) back, is this:

 Bundle intentExtras = new Bundle();
        intentExtras = getIntent().getExtras();
        Toast.makeText(this, "Page To Open: " + intentExtras.getString("pageId"), Toast.LENGTH_LONG).show();
        Toast.makeText(this, "Page To Open: " + intentExtras.getString("kategorieId"), Toast.LENGTH_LONG).show();

但是在两个"Toast"消息中，消息均显示为"null"，或者是第一次传递的值，请单击"Message".

But in both "Toast" Messages appears "null", or the value that was passed through at the first time, clicking on the Message.

例如: 第一次发送:intPageId = 1. 吐司面包说:要打开的页面:1".

For Example: At the First time I send: intPageId=1. The Toast says: "Page To Open: 1".

第二次我发送:intPageId = 2. 吐司面包说:要打开的页面:1".

At the Second time I send: intPageId=2. The Toast says: "Page To Open: 1".

我很困惑.

推荐答案

第一种方法:

代替下面的行:

PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intentOpen, 0);

将其更改为此:

PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intentOpen, PendingIntent.FLAG_UPDATE_CURRENT);

第二种方法:

int iUniqueId = (int) (System.currentTimeMillis() & 0xfffffff);

PendingIntent contentIntent = PendingIntent.getActivity(getApplicationContext(),iUniqueId, intentForNotification, 0);
