不显示 GCM 通知

Question

我正在使用 PUSH Notification.I 在接收来自 GCM 的消息时使用以下代码：

    public class MyGcmListenerService extends GcmListenerService {

    private static final String TAG = "MyGcmListenerService";

    /**
     * Called when message is received.
     *
     * @param from SenderID of the sender.
     * @param data Data bundle containing message data as key/value pairs.
     *             For Set of keys use data.keySet().
     */
    // [START receive_message]
    @Override
    public void onMessageReceived(String from, Bundle data) {
        String message = data.getString("message");
        Log.e(TAG, "From: " + from);
        Log.e(TAG, "Message: " + message);

        if (from.startsWith("/topics/")) {
            // message received from some topic.
        } else {
            // normal downstream message.
        }

        // [START_EXCLUDE]
        /**
         * Production applications would usually process the message here.
         * Eg: - Syncing with server.
         *     - Store message in local database.
         *     - Update UI.
         */

        /**
         * In some cases it may be useful to show a notification indicating to the user
         * that a message was received.
         */
        sendNotification(message);
        // [END_EXCLUDE]
    }
    // [END receive_message]

    /**
     * Create and show a simple notification containing the received GCM message.
     *
     * @param message GCM message received.
     */
    private void sendNotification(String message) {
        Intent intent = new Intent(this, WelcomeActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,PendingIntent.FLAG_ONE_SHOT);

        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                //.setSmallIcon(R.drawable.ic_stat_ic_notification)
                .setContentTitle("GCM Message")
                .setContentText(message)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

        NotificationManager notificationManager = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(1, notificationBuilder.build());
    }
}

消息已收到但未显示为notification.I不知道我在这里遗漏了什么。请帮助我解决问题。

public void notify (int id, Notification notification)

Post 在状态栏中显示的通知。如果同id的通知已经被你的应用发布过，并且还没有被取消，那么它将被更新后的信息所取代。

http://developer.android.com/reference/android/app/NotificationManager.html#notify%28int,%20android.app.Notification%29

public void showNotificationMessage(String title, String message, Intent intent) {

        if (TextUtils.isEmpty(message))
            return;

        int icon = R.drawable.ic_launcher;

        int mNotificationId = new Random().nextInt(5000);

        PendingIntent resultPendingIntent = PendingIntent.getActivity(mContext, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);

        NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();

        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(mContext);
        Notification notification = mBuilder.setSmallIcon(icon).setTicker(title).setWhen(0)
                .setAutoCancel(true)
                .setContentTitle(title)
                .setStyle(inboxStyle)
                .setContentIntent(resultPendingIntent)
                .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
//                .setLargeIcon(BitmapFactory.decodeResource(mContext.getResources(), icon))
                .setContentText(message)
                .build();

        NotificationManager notificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(mNotificationId, notification);
    }

希望这能让您了解通知在 android 中的工作原理。
