Zxing圖片拉伸解決 Android 二維碼掃描

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);
