Android 主动亮屏WakeLock

<!--权限 唤醒cpu ,点亮屏幕  miui 上有开关-->
    <uses-permission android:name="android.permission.WAKE_LOCK"/>

public static void lightUpScreen(Activity context) {
        ScreenUtil.setScreenAlwaysOn(context,true);
//        PARTIAL_WAKE_LOCK:保持CPU 运转，屏幕和键盘灯有可能是关闭的。
//        SCREEN_DIM_WAKE_LOCK：保持CPU 运转，允许保持屏幕显示但有可能是灰的，允许关闭键盘灯
//        过期:SCREEN_BRIGHT_WAKE_LOCK：保持CPU 运转，允许保持屏幕高亮显示，允许关闭键盘灯 ,WindowManager.LayoutParams#FLAG_KEEP_SCREEN_ON
//        FULL_WAKE_LOCK：保持CPU 运转，保持屏幕高亮显示，键盘灯也保持亮度

//        下面这俩要和上面的4个配合,才能使用
//        ACQUIRE_CAUSES_WAKEUP：强制使屏幕亮起，这种锁主要针对一些必须通知用户的操作.
//        ON_AFTER_RELEASE：当锁被释放时，保持屏幕亮起一段时间
