Android使用Zxing掃描二維碼改成豎屏後,後面的預覽畫面出現了展開,扭曲解決方案

更改CameraConfigurationManager.java檔案

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;
        }
再更改cameraResolution = getCameraResolution(parameters, screenResolution);為cameraResolution = getCameraResolution(parameters, screenResolutionForCamera);
