 二维码扫描  Android Zxing图片拉伸解决

Zxing是google提供的二维码扫描project

默认是横屏的  转换成竖屏后图片出现拉伸

这里提供解决的方法:

Zxing  改动 CameraConfigurationManager.java文件的

void initFromCameraParameters(Camera camera)方法

在 Log.d(TAG, "Screen resolution: " + screenResolution);这句之后添加

 

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
例如以下:

cameraResolution = getCameraResolution(parameters, screenResolutionForCamera);

 

 

不足之处请在下方留言  谢谢

希望对您实用
