GCM通知未显示通知中收到的消息 [英] GCM Notification Not Showing Message Received In Notification

问题描述

我已成功创建PUSH通知应用程序，但问题是收到的消息未显示在通知栏上。它只显示我在代码中设置的标题。

I have successfully create a PUSH Notification App but the problem is the Message Received is not getting displayed on notification bar. It only Displays the title which I have set in the code.

@Override
    protected void onMessage(Context context, Intent intent) {

        if(aController == null)
            aController = (Controller) getApplicationContext();

        Log.i(TAG, "Received message");
        String message = intent.getExtras().getString("price");

        aController.displayMessageOnScreen(context, message);
        // notifies user
        generateNotification(context, message);
    }

private static void generateNotification(Context context, String message) {

        int icon = R.drawable.ic_launcher;
        long when = System.currentTimeMillis();

        NotificationManager notificationManager = (NotificationManager)
                context.getSystemService(Context.NOTIFICATION_SERVICE);
        Notification notification = new Notification(icon, message, when);

        String title = context.getString(R.string.app_name);

        Intent notificationIntent = new Intent(context, MainActivity.class);
        // set intent so it does not start a new activity
        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
                Intent.FLAG_ACTIVITY_SINGLE_TOP);
        PendingIntent intent =
                PendingIntent.getActivity(context, 0, notificationIntent, 0);
        notification.setLatestEventInfo(context, title, message, intent);
        notification.flags |= Notification.FLAG_AUTO_CANCEL;

        // Play default notification sound
        notification.defaults |= Notification.DEFAULT_SOUND;

        //notification.sound = Uri.parse("android.resource://"+ context.getPackageName()+ "your_sound_file_name.mp3");

        // Vibrate if vibrate is enabled
        notification.defaults |= Notification.DEFAULT_VIBRATE;
        notificationManager.notify(0, notification);

    }

// Notifies UI to display a message.
    void displayMessageOnScreen(Context context, String message) {

        Intent intent = new Intent(Config.DISPLAY_MESSAGE_ACTION);
        intent.putExtra(Config.EXTRA_MESSAGE, message);



        // Send Broadcast to Broadcast receiver with message
        context.sendBroadcast(intent);

    }

推荐答案

我认为你需要请包含以下代码：

I think you need to do include this code:

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
				this).setSmallIcon(R.drawable.gcm_cloud)
				.setContentTitle("GCM Notification")
				.setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
				.setContentText(yourMessage);

mBuilder.setContentIntent(intent );
notificationManager.notify(NOTIFICATION_ID, mBuilder.build());
Log.d(TAG, "Notification sent successfully.");
