我已经实现了以下方法来在 android 中显示一些通知。该方法与 developer.android.com 教程非常相似，但我的通知不会显示，无论是在 4.1 上还是在 4.0 或 2.3 上。

public void showNotification() {
    String appname = "App Name";
    String title = "Notification Title";
    String text = "This is the notification text";
    String iconUrl = "http://url.to.image.com/image.png";
    Bitmap largeIcon = imageCache.getBitmap(iconUrl);
    NotificationManager notifyManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

    TaskStackBuilder stackBuilder = TaskStackBuilder.from(context);
    stackBuilder.addParentStack(NewsActivity.class);
    stackBuilder.addNextIntent(new Intent(context, NewsActivity.class));
    PendingIntent pendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
    builder.setContentTitle(title).setContentInfo(appname).setLargeIcon(largeIcon).setContentText(text).setContentIntent(pendingIntent);

    notifyManager.notify("textid", 123, builder.getNotification());
}

小图标是通知的必需元素。

builder.setSmallIcon(R.drawable.notification_icon);

这是状态栏中显示的图标。

试试这个：

notifyManager.notify("textid", 123, builder.build());
