基于海康威视网络摄像机的Android二次开发

最近的一次开发工作中，需要开发一个app里面包含海康威视摄像机的监控和控制部分，通过各种网络资源，终于实现的所需要的功能，下面是我开发过程中的监控部分的代码和步骤，分享给大家，希望有所帮助，同时也是对网上资源的感谢。我的开发是使用Android studio，在局域网环境下，将几个摄像机插到路由器上，然后手机和摄像机在同一网段下实现的监控。

实现效果：

效果展示之后，接下来就是开发步骤了，在我的开发过程当中，我花费了相当一部分时间去找海康的sdk和jar包，先是在百度上找，好多不可以用，后来在海康售后那获得了sdk（文末会提供源码下载地址）。准备工作完成后接下来就是实现步骤了。

1.首先我们需要导入sdk和jar包，这里不再赘述，直接放目录截图

2.千万不要忘记开启权限，我忘记开启权限，导致耽误了好长一段时间：

  <uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/><uses-permission android:name="android.permission.CAPTURE_AUDIO_OUTPUT"/><uses-permission android:name="android.permission.RECORD_AUDIO"/>

3.我们导入jar包和sdk后需要在gradle中引入，同步。将下面两段代码放入对应bulid.gradle中

 sourceSets.main {jniLibs.srcDirs = ['libs']}compile files('libs/AudioEngineSDK.jar')compile files('libs/HCNetSDK.jar')compile files('libs/jna.jar')compile files('libs/PlayerSDK.jar')

4.接下来，我们编写布局，下面是我的布局文件代码。

<?xml version="1.0" encoding="utf-8"?>
<AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="fill_parent"android:layout_height="fill_parent"android:fillViewport="true"android:focusableInTouchMode="true"><LinearLayoutandroid:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"><TextViewandroid:layout_width="match_parent"android:layout_height="40dp"android:text="   "android:textSize="15dp"/><LinearLayoutandroid:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="horizontal"><TextViewandroid:layout_width="7dp"android:layout_height="wrap_content"android:text="   "/><Buttonandroid:id="@+id/btn_Login"android:layout_width="115dip"android:layout_height="wrap_content"android:text="西南摄像机"android:textColor="#ff000000"android:typeface="sans"android:layout_below="@+id/EDT_User"android:layout_alignParentStart="true"android:layout_marginTop="12dp" /><Buttonandroid:id="@+id/btn_Login2"android:layout_width="115dip"android:layout_height="wrap_content"android:text="东南摄像机"android:textColor="#ff000000"android:typeface="sans"android:layout_below="@+id/EDT_User"android:layout_alignParentStart="true"android:layout_marginTop="12dp" /><Buttonandroid:id="@+id/btn_Login3"android:layout_width="115dip"android:layout_height="wrap_content"android:layout_alignParentStart="true"android:layout_below="@+id/EDT_User"android:layout_marginTop="12dp"android:text="东北摄像机"android:textColor="#ff000000"android:typeface="sans" /></LinearLayout><LinearLayoutandroid:id="@+id/Play"android:layout_width="fill_parent"android:layout_height="wrap_content"android:orientation="horizontal"><TextViewandroid:layout_width="10dp"android:layout_height="match_parent"android:text="  "/><SurfaceViewandroid:id="@+id/Sur_Player"android:layout_width="340dp"android:layout_height="370dp"android:layout_alignParentLeft="true"android:layout_below="@+id/btn_Login"android:background="#0000ff00" /></LinearLayout><LinearLayoutandroid:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="horizontal"><TextViewandroid:layout_width="7dp"android:layout_height="wrap_content"android:text="   "/><Buttonandroid:id="@+id/btn_Preview"android:layout_width="150dip"android:layout_height="wrap_content"android:text="播放"android:textColor="#ff000000"android:typeface="sans"android:layout_above="@+id/Sur_Player"android:layout_toEndOf="@+id/btn_Login" /><TextViewandroid:layout_width="46dp"android:layout_height="wrap_content"android:text="   "/><Buttonandroid:id="@+id/btn_PTZ"android:layout_width="150dip"android:layout_height="wrap_content"android:text="转向"android:textColor="#ff000000"android:typeface="sans"android:layout_above="@+id/Sur_Player"android:layout_toEndOf="@+id/btn_Preview" /></LinearLayout></LinearLayout></AbsoluteLayout>

5.下面就是开始编写最重要的部分了，在MainActivity中：

a.我们需要做的就是连接摄像机（登陆），需要密码，账号，IP，端口信息。以我的为例（admin，admin123， 192.168.137.1，8001）.

  m_oLoginBtn.setOnClickListener(new View.OnClickListener(){@Overridepublic void onClick(View v) {m_oIPAddr = "192.168.137.1";m_oPort = "8001";try {if (m_iLogID < 0) {// login on the devicem_iLogID = loginDevice();if (m_iLogID < 0) {Log.e(TAG, "This device logins failed!");return;} else {System.out.println("m_iLogID=" + m_iLogID);}// get instance of exception callback and setExceptionCallBack oexceptionCbf = getExceptiongCbf();if (oexceptionCbf == null) {Log.e(TAG, "ExceptionCallBack object is failed!");return;}if (!HCNetSDK.getInstance().NET_DVR_SetExceptionCallBack(oexceptionCbf)) {Log.e(TAG, "NET_DVR_SetExceptionCallBack is failed!");return;}m_oLoginBtn.setText("Logout");Log.i(TAG,"Login sucess ****************************1***************************");} else {// whether we have logoutif (!HCNetSDK.getInstance().NET_DVR_Logout_V30(m_iLogID)) {Log.e(TAG, " NET_DVR_Logout is failed!");return;}m_oLoginBtn.setText("西南摄像机");m_iLogID = -1;}} catch (Exception err) {Log.e(TAG, "error: " + err.toString());}}});

b.接下来就是需要实现我们的播放点击事件了，直接贴代码：

m_oPreviewBtn.setOnClickListener(new View.OnClickListener(){public void onClick(View v) {try {if (m_iLogID < 0) {Log.e(TAG, "please login on device first");return;}if (m_bNeedDecode) {if (m_iChanNum > 1)// preview more than a channel{if (!m_bMultiPlay) {m_bMultiPlay = true;m_oPreviewBtn.setText("停止");} else {stopMultiPreview();m_bMultiPlay = false;m_oPreviewBtn.setText("播放");}} else // preivew a channel{if (m_iPlayID < 0) {startSinglePreview();} else {stopSinglePreview();m_oPreviewBtn.setText("播放");}}} else {}} catch (Exception err) {Log.e(TAG, "error: " + err.toString());}}});

c.最后就是我们的控制button，这里我将左转和右转写到一个button上，第一次点击左转，第二次点击右转：

m_oPTZBtn.setOnTouchListener(new OnTouchListener() {public boolean onTouch(View v, MotionEvent event) {try {if (m_iLogID < 0) {Log.e(TAG, "please login on a device first");return false;}if (event.getAction() == MotionEvent.ACTION_DOWN) {if (m_bPTZL == false) {if (!HCNetSDK.getInstance().NET_DVR_PTZControl_Other(m_iLogID, m_iStartChan, PTZCommand.PAN_LEFT, 0)) {Log.e(TAG,"start PAN_LEFT failed with error code: "+ HCNetSDK.getInstance().NET_DVR_GetLastError());} else {Log.i(TAG, "start PAN_LEFT succ");}} else {if (!HCNetSDK.getInstance().NET_DVR_PTZControl_Other(m_iLogID,m_iStartChan, PTZCommand.PAN_RIGHT, 0)) {Log.e(TAG,"start PAN_RIGHT failed with error code: "+ HCNetSDK.getInstance().NET_DVR_GetLastError());} else {Log.i(TAG, "start PAN_RIGHT succ");}}} else if (event.getAction() == MotionEvent.ACTION_UP) {if (m_bPTZL == false) {if (!HCNetSDK.getInstance().NET_DVR_PTZControl_Other(m_iLogID, m_iStartChan, PTZCommand.PAN_LEFT, 1)) {Log.e(TAG, "stop PAN_LEFT failed with error code: "+ HCNetSDK.getInstance().NET_DVR_GetLastError());} else {Log.i(TAG, "stop PAN_LEFT succ");}m_bPTZL = true;m_oPTZBtn.setText("右转");} else {if (!HCNetSDK.getInstance().NET_DVR_PTZControl_Other(m_iLogID,m_iStartChan, PTZCommand.PAN_RIGHT, 1)) {Log.e(TAG,"stop PAN_RIGHT failed with error code: "+ HCNetSDK.getInstance().NET_DVR_GetLastError());} else {Log.i(TAG, "stop PAN_RIGHT succ");}m_bPTZL = false;m_oPTZBtn.setText("左转");}}return true;} catch (Exception err) {Log.e(TAG, "error: " + err.toString());return false;}}});
