推荐答案

谷歌这个问题。

我已经使用zxing zxing 2.3及以下的解决方案，为我工作。

I have used zxing zxing 2.3 and below solution worked for me.

1在CameraConfigurationManager类，setDesiredCameraParameters方法添加以下的尖线code

1 In CameraConfigurationManager class, setDesiredCameraParameters Method add below code below pointed line

- > Camera.Parameters参数= camera.getParameters（）;

-> Camera.Parameters parameters = camera.getParameters();

 if (context.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
        camera.setDisplayOrientation(90);
 }

2在CameraManager类，getFramingRect方法替换code如下

2 In CameraManager class, getFramingRect Method replace code as below

int width = MIN_FRAME_WIDTH; int height = MIN_FRAME_HEIGHT;
if (context.getResources().getConfiguration().orientation ==Configuration.ORIENTATION_PORTRAIT) {
   int tmp = 7 * screenResolution.x / 8; 
   width = (tmp) < MIN_FRAME_WIDTH ? MIN_FRAME_WIDTH : (tmp);                   
   tmp = 1 * screenResolution.y / 3;
   height = (tmp) < MIN_FRAME_WIDTH ? MIN_FRAME_WIDTH : ((tmp) > MAX_FRAME_HEIGHT ?  MAX_FRAME_HEIGHT : (tmp));
}else{
   // Original Code
   width = findDesiredDimensionInRange(screenResolution.x, MIN_FRAME_WIDTH, > MAX_FRAME_WIDTH);
   height = findDesiredDimensionInRange(screenResolution.y, MIN_FRAME_HEIGHT,  MAX_FRAME_HEIGHT); 
}

3在CameraManager类，getFramingRectIn preVIEW方法代替code如下

3 In CameraManager class, getFramingRectInPreview Method replace code as below

if (context.getResources().getConfiguration().orientation ==Configuration.ORIENTATION_PORTRAIT) {
   rect.left = rect.left * cameraResolution.y / screenResolution.x;
   rect.right = rect.right * cameraResolution.y / screenResolution.x;
   rect.top = rect.top * cameraResolution.x / screenResolution.y;
   rect.bottom = rect.bottom * cameraResolution.x / screenResolution.y;
}else{
   // Original code commented
   rect.left = rect.left * cameraResolution.x / screenResolution.x;
   rect.right = rect.right * cameraResolution.x / screenResolution.x;
   rect.top = rect.top * cameraResolution.y / screenResolution.y;
   rect.bottom = rect.bottom * cameraResolution.y / screenResolution.y;
}

4在德$ C $钱德勒类，德code方法添加以下的尖线code

4 In DecodeHandler class, decode Method add below code below pointed line

- >结果rawResult = NULL;

-> Result rawResult = null;

 if (activity.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT){
        byte[] rotatedData = new byte[data.length];
        for (int y = 0; y < height; y++) {
            for (int x = 0; x < width; x++)
                rotatedData[x * height + height - y - 1] = data[x + y * width];
        }
        data = rotatedData;
        int tmp = width;
        width = height;
        height = tmp;

  }
