view.setTextViewText(R.id.tv, "下载" + progress + "%");// 关键部分，如果你不重新更新通知，进度条是不会更新的

// 设置通知在状态栏显示的图标

notification.icon = R.drawable.icon;

// 通知时发出的默认声音

notification.defaults = Notification.FLAG_ONLY_ALERT_ONCE;

// 通过RemoteViews 设置notification中View 的属性

       notification.contentView = view;

    notification.contentIntent = pendingIntent;

// 这个可以理解为开始执行这个通知
