解决Android使用Zxing扫描二维码改成竖屏后,后面的预览画面出现了拉伸,扭曲的情况

完美解决Android使用Zxing扫描二维码改成竖屏后,后面的预览画面出现了拉伸,扭曲的情况

第一步：找到com.zxing.camera包下的CameraConfigurationManager.java文件中的void initFromCameraParameters(Camera camera)方法

第二步：在 Log.d(TAG, Screen resolution: + screenResolution);后加上如下的代码

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;
}

第三步：替换screenResolution为screenResolutionForCamera

cameraResolution = getCameraResolution(parameters, screenResolution);  

找到上边的代码替换成下边的代码(如下图)

cameraResolution = getCameraResolution(parameters, screenResolutionForCamera);

第四步：最后的修改效果为
