perfect solution to solve Android using zxing scan QR code changed to vertical screen, after the preview screen appeared stretched, distorted situation

First step: Find com.zxing.cameraUnder the bag CameraConfigurationManager.javaIn the file void initFromCameraParameters(Camera camera)Method

Step two: In Log.d(TAG, "Screen resolution: " + screenResolution);Then add the following code

new Point();screenResolutionForCamera.x = screenResolution.x;screenResolutionForCamera.y = screenResolution.y;// preview size is always something like 480*320, other 320*480if (screenResolution.x < screenResolution.y) {    screenResolutionForCamera.x = screenResolution.y;    screenResolutionForCamera.y = screenResolution.x;}

Step Three: Replace screenResolutionFor screenResolutionForCamera

cameraResolution = getCameraResolution(parameters, screenResolution);  

Find the code above and replace it with the code below (e.g.)

cameraResolution = getCameraResolution(parameters, screenResolutionForCamera);

Interested children's shoes can follow my blog, my column will continue to update the Android Studio authoritative tutorial, as well as I/O assembly on the NDK configuration and compilation, I will also share to everyone.
And I received an invitation from CSND's instructor, and later I'll record the use of these Android studio videos.
