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、MonitorCameraInfo.java(监控点信息类)

2、Sjrs08SurfaceView.java(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

AndroidManifest.xml中只需定义一项网络访问的权限：

下面是源代码：

1、MonitorCameraInfo.java

package com.sjrs08.HCNetSDK.Player.demo;

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、Sjrs08SurfaceView.java

package com.sjrs08.HCNetSDK.Player.demo;

import org.MediaPlayer.PlayM4.Player;

import android.content.Context;

import android.util.AttributeSet;

import android.view.MotionEvent;

private int playPort = -1; //播放端口

private int userId = -1; //登录帐号id

private MonitorCameraInfo cameraInfo = null; //监控点信息

private SurfaceHolder holder = null;

public Sjrs08SurfaceView(Context paramContext) {

}

return false;

}

}

public boolean onScroll(MotionEvent paramMotionEvent1,

MotionEvent paramMotionEvent2, float paramFloat1, float paramFloat2) {

return false;

}

public void onShowPress(MotionEvent paramMotionEvent) {

}

public boolean onSingleTapUp(MotionEvent paramMotionEvent) {

return false;

}

public void surfaceChanged(SurfaceHolder paramSurfaceHolder, int paramInt1,

int paramInt2, int paramInt3) {

}

public void surfaceCreated(SurfaceHolder paramSurfaceHolder) {

holder = this.getHolder();

}

public void surfaceDestroyed(SurfaceHolder paramSurfaceHolder) {

}

public void setMonitorInfo(MonitorCameraInfo setMonitorInfo) {

this.cameraInfo = setMonitorInfo;

}

}

@Override

protected void onResume() {

super.onResume();

if (!nowSjrs08SurfaceView.playFlag) { //如果没有在播放的话

MonitorCameraInfo cameraInfo = new MonitorCameraInfo();

cameraInfo.serverip = "192.168.0.100";

cameraInfo.serverport = 8000;

cameraInfo.username = "ceshiadmin";

cameraInfo.userpwd = "123456";

cameraInfo.channel = 1;

cameraInfo.describe = "测试点";

nowSjrs08SurfaceView.setMonitorInfo(cameraInfo);

nowSjrs08SurfaceView.startPlay(); //开始实时预览

}

}

@Override

protected void onPause() {

super.onPause();

if (nowSjrs08SurfaceView.playFlag) {

nowSjrs08SurfaceView.stopPlay(); //停止实时预览

}

}

}
