查看相机支持的尺寸：

 for (Camera.Size size : parameters.getSupportedPreviewSizes()) {
            int width = Math.min(size.width, size.height);
            int height = Math.max(size.width, size.height);
            int max=WindowsUtils.getGYS(width,height);
            Log.e("预览尺寸","屏宽比："+width/max+","+height/max+"--->相机的预览尺寸为height="+height+"width="+width);
        }
