我知道为时已晚，但可以帮助其他人只需转到相机管理器类并将此代码粘贴到替换给定方法上它适用于所有类型的屏幕

    public Rect getFramingRect() {
    if (framingRect == null) {
    if (camera == null) {
    return null;
    }
    Point screenResolution = configManager.getScreenResolution();
    int width = screenResolution.x * 3 / 4;

    int height = screenResolution.y * 3 / 4;
    Log.v("Framing rect is : ", "width is "+width+"   and height is "+height);
    int leftOffset = (screenResolution.x - width) / 2;
    int topOffset = (screenResolution.y - height) / 2;
    framingRect = new Rect(leftOffset, topOffset, leftOffset + width, topOffset + height);
    Log.d(TAG, "Calculated framing rect: " + framingRect);
    }
    return framingRect;
   }
