Question

我是Android编程的巨大菜鸟，很抱歉，如果这是一个简单的任务。我几乎关注了推送通知的Vogella推送通知教程（http://www.vogella.com/articles/AndroidCloudToDeviceMessaging/article.html）。我已经阅读了其他一些堆栈溢出问题但是在收到通知后我对如何打开一个意图感到有点困惑。

例如，如果我只是想让通知引导我访问某个网站，那该怎么办？它是否必须一起在我的MessageReceivedActivity或其他项目/类下？

由于

以下是我的C2DMMessageReceiver

的代码

@Override
public void onReceive(Context context, Intent intent) {
    String action = intent.getAction();
    Log.w("C2DM", "Message Receiver called");
    if ("com.google.android.c2dm.intent.RECEIVE".equals(action)) {
        Log.w("C2DM", "Received message");
        final String payload = intent.getStringExtra("payload");
        Log.d("C2DM", "dmControl: payload = " + payload);
        // TODO Send this to my application server to get the real data
        // Lets make something visible to show that we received the message
        createNotification(context, payload);

    }
}

public void createNotification(Context context, String payload) {
    NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = new Notification(R.drawable.ic_launcher,
            "Message received", System.currentTimeMillis());
    // Hide the notification after its selected
    notification.flags |= Notification.FLAG_AUTO_CANCEL;

    //adding LED lights to notification
    notification.defaults |= Notification.DEFAULT_LIGHTS;

    Intent intent = new Intent(context, MessageReceivedActivity.class);
    intent.putExtra("payload", payload);

    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
            intent, 0);
    notification.setLatestEventInfo(context, "Message",
            "New message received", pendingIntent);
    notificationManager.notify(0, notification);

}

}

如果您想在通知上打开网站，请点击试试这个：

    public void createNotification(Context context, String payload) {
        NotificationManager notificationManager = (NotificationManager) context
                .getSystemService(Context.NOTIFICATION_SERVICE);
        Notification notification = new Notification(R.drawable.ic_launcher,
                "Message received", System.currentTimeMillis());
        // Hide the notification after its selected
        notification.flags |= Notification.FLAG_AUTO_CANCEL;

        //adding LED lights to notification
        notification.defaults |= Notification.DEFAULT_LIGHTS;

        Intent intent = new Intent("android.intent.action.VIEW", 
         Uri.parse("http://my.example.com/"));
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
                intent, 0);
        notification.setLatestEventInfo(context, "Message",
                "New message received", pendingIntent);
        notificationManager.notify(0, notification);

    }

在c2dm的基本接收器或扩展基本接收器的类中，你有一个handleMessage（）::

下面是启动activity ::

的句柄消息的示例代码

@Override
    protected void handleMessage(Context context, Intent intent) {
        String regId = C2DMessaging.getRegistrationId(context);
        String logKey = this.getClass().getSimpleName();
        String title="";
        String message="";
        if (regId!= null) {
            if (intent.hasExtra(Constants.TITLE)) {
                title = intent.getStringExtra(Constants.TITLE);
            }
            if(intent.hasExtra(Constants.MESSAGE)){
                message = intent.getStringExtra(Constants.MESSAGE);
            }
            // TODO Send this to my application server to get the real data
            // Lets make something visible to show that we received the message
            if(!title.equals("") && !message.equals(""))
                createNotificationForMsg(context,title,message);
        }
    }

    @Override
    public void createNotificationForMsg(Context context,String title,String message) {
        final String logKey = this.getClass().getSimpleName();

        try {
            NotificationManager notificationManager = (NotificationManager) context
                    .getSystemService(Context.NOTIFICATION_SERVICE);
            Notification notification = new Notification(R.drawable.icon,
                    "update(s) received", System.currentTimeMillis());
            // Hide the notification after its selected
            notification.flags |= Notification.FLAG_AUTO_CANCEL;
            //adding sound to notification
            notification.defaults |= Notification.DEFAULT_SOUND;            

                Intent intent = new Intent(context, YourAlertActivity.class);

                if(Constants.LOG)Log.d(logKey, Constants.TITLE +": "+ title +" , "+Constants.MESSAGE+": "+message);
                intent.putExtra(Constants.TITLE, title);
                intent.putExtra(Constants.MESSAGE, message);

                PendingIntent pendingIntent = PendingIntent.getActivity(context, Calendar.getInstance().get(Calendar.MILLISECOND),  intent, android.content.Intent.FLAG_ACTIVITY_NEW_TASK);
                notification.setLatestEventInfo(context, "Castrol",
                        title+"update Received", pendingIntent);
                notificationManager.notify(Calendar.getInstance().get(Calendar.MILLISECOND), notification);



        } catch (Exception e) {
//          MessageReceivedActivity.view.setText("createNotificationFor Msg: "
//                  + e.toString());
        }
    }
