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);
