Question

对于我正在创建的活动，我希望能够在调用方法时将LED的颜色（指示充电状态的相同LED）更改为Solid RED，并在调用其他方法时将Solid Green更改为Solid Green。到目前为止，我没有尝试过任何工作。也许这在HTC手机上是不可能的。我正在使用HTC Desire 626.我尝试了我的功能，设备插入并没有插入USB。似乎根本没有改变这个通知。我没有看到任何需要包含的特殊权限，我在LogCat中没有例外。

我将提供更改LED的方法，请帮忙！

private void notification_RED(){
    AccelerometerResult.setText("The Indicator light should now be Red");
    AccelerometerResult.setTextColor(Color.RED);
    String ns = getApplicationContext().NOTIFICATION_SERVICE;
    NotificationManager mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

    Notification notification = new Notification();
    notification.flags = Notification.FLAG_SHOW_LIGHTS;
    notification.defaults = 0;
    notification.ledARGB = 0xff0000ff;
    //notification.ledARGB = Color.RED;
    notification.priority = Notification.PRIORITY_MAX;
    notification.ledOnMS = 1000;
    notification.ledOffMS = 300;
    mNotificationManager.notify(1, notification);
}

private void notification_GREEN(){
    AccelerometerResult.setText("The Indicator light should now be GREEN");
    AccelerometerResult.setTextColor(Color.GREEN);

    String ns = getApplicationContext().NOTIFICATION_SERVICE;
    NotificationManager mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

    Notification notification = new Notification();
    notification.flags = Notification.FLAG_SHOW_LIGHTS;
    notification.ledARGB = Color.GREEN;
    notification.priority = Notification.PRIORITY_DEFAULT;
    notification.ledOnMS = 1000;
    notification.ledOffMS = 300;

    mNotificationManager.notify(1, notification);

}

此灯只能在手机锁定时更改。这就是为什么它被称为通知灯。要在屏幕开启时通知某事，请使用Toast，弹出窗口或通知。
