更新一个抓图功能代码见最底部

目前海康威视官网上并没有提供Android的API和SKD所以下面的SDK是反编译后得到的。
效果图“现在”截不了，不是我不给图。公司上面有人在调试硬件设备

1.先了解下大概的部署图都属于（直连的性质）：
自己随便画的有点丑。。。别喷
2.也可以部署某个服务器到互联网上、使用手持设备（android）通过联网直接远程控制摄像头等等是可行的、这就看亲们自己的想想力了。

3.此文用于交流不涉及商业信息、如有雷同不胜荣幸。

4.现在Demo已经实现的功能：

4.1.简单的八个方向控制

5.正在完善的功能：

5.1.抓图、录像、远程关机重启、多屏展示等等后续有完善的功能继续更新

下面咱们开始看代码：

1、MonitorCameraInfo.java（监控点信息类）

2、SjrsSurfaceView.java（继承自SurfaceView，用来播放视频并显示）

3、VideoShowActivity（主activity）

4、清单文件中一定要加上网络访问的权限 android.permission.INTERNET

5、获取视频展示有两种，一种是文件模式，一种是流模式(我用的是流模式)

6、下面是工程结构图，需要完整的可以下Demo研究，咱们可以互相交流

按照官网提供的调用顺序如下：

最近有些忙就弄了一个“抓图”功能，勿喷勿喷

这个代码你可以自己弄个按钮来触发，不多说了

                     }

            }

            Toast.makeText(VideoShowActivity.this, "截取成功，保存在SDK的" + cameraInfo.filepath + "下", 1).show();
