Android Zxing二維碼掃描圖片拉伸的解決方法

二維碼掃描，Android Zxing圖片拉伸解決。

Zxing是google提供的二維碼掃描工程

默認是橫屏的  轉換成豎屏後圖片出現拉伸 

這裡提供解決辦法: 

Zxing 修改 CameraConfigurationManager.Java文件的void initFromCameraParameters(Camera camera)方法 

在Log.d(TAG, "Screen resolution: " + screenResolution);這句之後增加  

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;
  }

在把其後的
cameraResolution = getCameraResolution(parameters, screenResolution);  
中的screenResolution改為screenResolutionForCamera
如下:
cameraResolution = getCameraResolution(parameters, screenResolutionForCamera);
