上一篇文章写了《海康威视远程监控Android端APP开发初探》，闲来又整理了一下demo，现在把demo工程的源码发上来，大家一起学习：
工程源文件三个：
1、(监控点信息类)
2、(继承自SurfaceView，用来播放视频并显示)
3、VideoShowActivity(主activity)
布局文件一个：
activity_main.xml
中只需定义一项网络访问的权限：
下面是源代码：
1、
package com.;
public class MonitorCameraInfo {
public String serverip = "";
public int serverport = 0;
public String username = "";
public String userpwd = "";
public int channel = 0;
public String describe = "";
public MonitorCameraInfo() {
}
}
2、
