Zxing图片拉伸解决 Android 二维码扫描

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);

 这样就大功告成了，快去试试吧！
