Zxing图片拉伸解决 Android 二维码扫描

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);
