* 设置surfaceView的尺寸 因为camera默认是横屏，所以取得支持尺寸也都是横屏的尺寸
* 我们在startPreview方法里面把它矫正了过来，但是这里我们设置设置surfaceView的尺寸的时候要注意 previewSize.height&previewSize.width
* previewSize.width才是surfaceView的高度
* 一般相机都是屏幕的宽度 这里设置为屏幕宽度 高度自适应 你也可以设置自己想要的大小
picHeight = (screenWidth * pictrueSize.width) / pictrueSize.
FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(screenWidth, (screenWidth * pictrueSize.width) / pictrueSize.height);
surfaceView.setLayoutParams(params);
