Android LED_NOTIFICATION_ID 无法解析为变量

Question

我查找了有关如何让 Android 设备 LED 闪烁的示例，并且收到了有关无法将 LED_NOTIFICATION_ID 解析为变量的消息。我的代码如下。有谁可以告诉我为什么会收到此错误？

private void redFlashLight(Context context)
    {
        NotificationManager nm = ( NotificationManager ) context.getSystemService( context.NOTIFICATION_SERVICE );
        Notification notif = new Notification();
        notif.ledARGB = 0xFFff0000;
        notif.flags = Notification.FLAG_SHOW_LIGHTS;
        notif.ledOnMS = 100; 
        notif.ledOffMS = 100; 
        notif.flags = Notification.FLAG_SHOW_LIGHTS | Notification.FLAG_ONLY_ALERT_ONCE;
        nm.notify(LED_NOTIFICATION_ID, notif);
    }

Answer 1

那时您还没有将 LED_NOTIFICATION_ID 声明为变量。查找拼写错误。它应该用类名来限定吗？
