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

问题描述

我有我的Andr​​oid应用程序有问题。它通过谷歌云消息接收消息并显示在Notificationbar的通知。我想用传送通知一些数据。该数据来自通过谷歌云消息，应attatched的通知。

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 attatched to the Notification.

这是我的code显示通知：

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());

    }

和我的code来获得在其他活动中的可变因素intPageId和intCategorieId（巫婆通过单击通知打开）回来了，是这样的：

And my Code to get the Varibles "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();

但在这两个吐司的消息出现空，或通过在第一时间传递的值，点击该消息。

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

例如：
在第一时间我送：intPageId = 1。
敬酒说：页面打开：1。

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

在我第二次送：intPageId = 2。
敬酒说：页面打开：1。

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

我完全糊涂了，希望有人能帮助我。

I'm totally confused and hope someone can help me.

（对不起，spelling-和语法错误）

(Sorry for spelling- and grammatical errors)

推荐答案

第一种方法：

而不是下面一行：

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

改成这样：

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);
