Android笔记：Zing二维码扫描解决二维码被拉伸

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);
