ZXing 二维码Surface拉伸问题处理

原因：

zxing横屏变竖屏之后，Camera的代码还是采用的横屏代码设置的参数

定位：

CameraConfigurationManager.java文件

方法：

initFromCameraParameters方法中，

在 Log.d(TAG, "Screen resolution: " + screenResolution);这句之后增加
Point screenResolutionForCamera = new Point();
screenResolutionForCamera.x = screenResolution.x;
screenResolutionForCamera.y = screenResolution.y;
        
if (screenResolution.x < screenResolution.y) {
screenResolutionForCamera.x = screenResolution.y;
screenResolutionForCamera.y = screenResolution.x;
 }

再将cameraResolution = getCameraResolution(parameters, screenResolution);

更改为

cameraResolution = getCameraResolution(parameters, screenResolutionForCamera);
