Android Zxing二维码扫描图片拉伸的解决方法

二维码扫描，Android Zxing图片拉伸解决。

Zxing是google提供的二维码扫描工程

默认是横屏的  转换成竖屏后图片出现拉伸 

这里提供解决办法: 

Zxing 修改 CameraConfigurationManager.Java文件的void initFromCameraParameters(Camera camera)方法

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;
 // preview size is always something like 480*320, other 320*480
 if (screenResolution.x < screenResolution.y) {
 screenResolutionForCamera.x = screenResolution.y;
 screenResolutionForCamera.y = screenResolution.x;
 }

在把其后的
cameraResolution = getCameraResolution(parameters, screenResolution);  
中的screenResolution改为screenResolutionForCamera
如下:
cameraResolution = getCameraResolution(parameters, screenResolutionForCamera);
