在你的activity课上，使用下面的方法:（检查方向和控制亮度）

 @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);

        // Checks the orientation of the screen
        if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
                    Settings.System.putInt(context.getContentResolver(),
               Settings.System.SCREEN_BRIGHTNESS, 0);
        } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
                   Settings.System.putInt(context.getContentResolver(),
               Settings.System.SCREEN_BRIGHTNESS, 100);
        }
    }
