两种背景灯设置
1.getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON, WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
?
2.
PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE); ??
wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK, "DoNotDimScreen");?
这两种好像没啥区别 除了一个要权限一个不要
