Android之Zxing二维码扫描图片拉伸

还是这个接手项目，二维码扫描集成的是zxing，扫描界面的图像有明显的拉伸变形。

这种问题，根据以往的经验，一般是x，y轴错位引起的，处理好x，y轴的问题，一般可以解决问题。

由于这个问题，之前有很多人遇到，并分享在网上了，所以，我这里也就不需要重复造轮子了。

这里看了一篇博客：http://blog.csdn.net/aaawqqq/article/details/24852915，用了上面的办法，

成功的解决图片拉伸问题。

解决方法如下：

修改CameraConfigurationManager.Java里面的initFromCameraParameters方法：

void initFromCameraParameters(Camera camera) {
    Camera.Parameters parameters = camera.getParameters();
    previewFormat = parameters.getPreviewFormat();
    previewFormatString = parameters.get("preview-format");
    Log.d(TAG, "Default preview format: " + previewFormat + '/' + previewFormatString);
    WindowManager manager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
    Display display = manager.getDefaultDisplay();
    screenResolution = new Point(display.getWidth(), display.getHeight());
    Log.d(TAG, "Screen resolution: " + screenResolution);

    //added
    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;
    }
    cameraResolution = getCameraResolution(parameters, screenResolutionForCamera);

//    cameraResolution = getCameraResolution(parameters, screenResolution);
    Log.d(TAG, "Camera resolution: " + screenResolution);
  }
