【思路】1、在滑动回调里发送广播给 BrightnessDialog 后台进行计算，同样以BrightnessDialog 的num值作为是否关闭对话框的标准。（解决：滑动时不会消失）2、在滑动回调将异步操作改为动态操作（解决：点击或滑动不能动态改变亮度值和动画效果）frameworks/base/packages/SystemUI/src/com/android/systemui/setting

【思路】1、每次点击亮度键时，我们需要发送一个广播给BrightnessDialog 进行后台计算2、创建 num变量，表示 来回点击标志。3、BrightnessDialog.java 的后台， 判断对话框是否需要自动关闭，每三秒请求一次，以num为状态标准4、判断逻辑为：每次点击num+1，三秒后计时器请求判断对话框是否需要自动关闭，若num为0就会关闭，若num不为0，则继续显示且重新在后台
△注意：这里有一个坑点。功能我们Framework这边是实现了，但是有时候Ctrl+FN一旦组合使用后，会导致其他按键不正常，经排查是由于Ctrl键一直处于锁定状态（按下状态），为什么呢？我可以告诉你，这是驱动上报事件写的问题，因为我不知道驱动已经写好了这样的事件，导致自己写了一个估计与他们产生了冲突，只要是组合键他只会上报CTRL+FN的组合键值，并不会上报给我CTRL和FN的单个键值，所以导致
