本文解决了使用ZXing进行条形码扫描时屏幕显示模糊的问题。通过对CameraManager中getFramingRectInPreview方法的调整，实现了清晰的扫描效果。

上面文章说的方法我用过后，屏幕变的很模糊，仅仅是因为第五步，所以不改变第五步的话，就改变第五步影响的参数吧，所以我把CameraManager中getFramingRectInPreview中的修改为：

      Rect rect = new Rect(framingRect);
      Point cameraResolution = configManager.getCameraResolution();
      Point screenResolution = configManager.getScreenResolution();
      rect.left = rect.left * cameraResolution.y / screenResolution.y;
      rect.right = rect.right * cameraResolution.y / screenResolution.y;
      rect.top = rect.top * cameraResolution.x / screenResolution.x;
      rect.bottom = rect.bottom * cameraResolution.x / screenResolution.x;
      framingRectInPreview = rect;

目前测试良好
