How to set the brightness

 
阅读更多 
android.provider.Settings.System.putInt(getContentResolver(),android.provider.Settings.System.SCREEN_BRIGHTNESS, brightness); // 0-255 
WindowManager.LayoutParams lp = getWindow().getAttributes();
lp.screenBrightness = brightness / 255.0f;
getWindow().setAttributes(lp);

 另外需要延迟关闭应用，大概需要延迟几百毫秒吧～
