Question

我在android.it中使用谷歌云消息显示警报正在某些设备和模拟器中工作，但不能正常工作，如Samsunng Galaxy Grand和我的一些模拟器，它只显示通知的图标和标题消息是空白的。

mNotificationManager = (NotificationManager) this
            .getSystemService(Context.NOTIFICATION_SERVICE);

    PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
            new Intent(this, MyActivity.class), 0);

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
            this).setSmallIcon(R.drawable.ic_launcher)
            .setContentTitle("Siom Alert")//TITLE CAN BE TSKEN FROM HERE
            .setStyle(new NotificationCompat.BigTextStyle().bigText(mes))
            .setContentText(mes);

    mBuilder.setContentIntent(contentIntent);
    mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());

Answer 1

请尝试这个。

// Put the message into a notification and post it.
// MainActivity is the activity which you wish to load. Setting setWhen() with 0 will not publish time.

private void sendNotification(String msg) {
    mNotificationManager = (NotificationManager)
            this.getSystemService(Context.NOTIFICATION_SERVICE);

    PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
            new Intent(this, MainActivity.class), 0);

    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.drawable.your_app_icon)
                    .setContentTitle(getResources().getText(R.string.your_title))
                    .setStyle(new NotificationCompat.BigTextStyle()
                            .bigText(msg))
                    .setWhen(0).setPriority(NotificationCompat.PRIORITY_HIGH)
                    .setContentText(msg)
                    .setAutoCancel(true);

    mBuilder.setContentIntent(contentIntent);
    mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}

我希望你拥有所需的权限。参考：GCM Reference

尝试这样可以帮到你

mNotificationManager = (NotificationManager) this
                .getSystemService(Context.NOTIFICATION_SERVICE);

        PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
                new Intent(this, MyActivity.class), 0);

    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN) {
      NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
                this).setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("Siom Alert")//TITLE CAN BE TSKEN FROM HERE
                .setStyle(new NotificationCompat.BigTextStyle().bigText(mes))
                .setContentText(mes);

    } else {
          //code for simple notification
    }

试试这段代码。

 private void generateNotification(Context context, String message) {
        long when = System.currentTimeMillis();
        NotificationManager notificationManager = (NotificationManager)   context.getSystemService(Context.NOTIFICATION_SERVICE);
        Notification notification = new Notification(R.drawable.ic_launcher, message, when);         
        String title = "New POC Alert";         
        Intent notificationIntent = new Intent(context, null);
        // 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;

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

// Mainfest权限

<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="vibrate" />
