推荐答案

使用的Camera.Size嵌套类

Use the Camera.Size nested class

从Android参考：

From the android reference:

类概述

Camera类用于设置图像捕获设置，启动/停止preVIEW，抓拍图片和检索视频编码帧。这个类是相机业务，其管理的实际摄像头硬件的客户端。

The Camera class is used to set image capture settings, start/stop preview, snap pictures, and retrieve frames for encoding for video. This class is a client for the Camera service, which manages the actual camera hardware.

请确保大小相机支持（并极有可能也不会）。如果不是这样，拍摄照片在最近的分辨率和裁剪或调整其大小。

Make sure that the size is supported by the camera (and most probably it won't). If not, take a picture at the closest resolution and crop it or resize it.

Camera myCamera = Camera.open(0);
List<Camera.Size> sizes = myCamera.getPArameters().getSupportedPictureSizes();

要了解相机的意图，在SO已经检查这些问题：
