android开发修改相机扫描二维码框的高宽

我用的是网上一个现成的例子,可以直接用,但是高宽不合适,现在主流都是大屏幕手机了,所以需要更改。

找到CameraManager 类,更改下面的方法

public Rect getFramingRect() {    Point screenResolution = configManager.getScreenResolution();    if (framingRect == null) {      if (camera == null) {        return null;      }      int width = screenResolution.x * 3 / 5;//      if (width < MIN_FRAME_WIDTH) {//        width = MIN_FRAME_WIDTH;//      } else if (width > MAX_FRAME_WIDTH) {//        width = MAX_FRAME_WIDTH;//      }      int height = screenResolution.y * 3 / 5;//      if (height < MIN_FRAME_HEIGHT) {//        height = MIN_FRAME_HEIGHT;//      } else if (height > MAX_FRAME_HEIGHT) {//        height = MAX_FRAME_HEIGHT;//      }        /* 自定义,以宽高其中一个窄的为正方形的边长 */        width = (width>height?height:width);        height = (width<height?width:height);      int leftOffset = (screenResolution.x - width) / 2;//      int topOffset = (screenResolution.y - height) / 2;        int topOffset = (screenResolution.y - height) / 2 - 40;  /* 自定义,放上一点 */      framingRect = new Rect(leftOffset, topOffset, leftOffset + width, topOffset + height);      Log.d(TAG, "Calculated framing rect: " + framingRect);    }    return framingRect;  }
