基于Android的TCP/IP调试助手Demo
来源：互联网 发布：程序员博客哪个好 编辑：程序博客网 时间：2024/05/20 04:29
经过一段时间的Android开发学习，本着学习的心态，再网上找了一个资源，做了一个TCP/IP 的调试助手，主要涉及socket通信。最后，由于感觉一个手机界面太过难看，用了现在网上用的普遍的方法，导入SlidingMenu-master包，做了个手机侧滑界面。总之，类似一些电脑上的串口调试助手，有数据发送区和数据接收区，主要有TCP客户端和TCP服务端两种模式。
程序大体流程：
1.在侧滑界面，由用户选择把手机作为连接模式，有“TCP客户端模式”和“TCP服务器模式”两种模式选择；
2.对应不同的模式，分配不同的功能
a.服务器模式：界面信息显示本地IP，可自行设置端口号，点击开启服务器按钮，开启TCP_service连接线程，启动serversocket，进行监听，当有客户端socket连接时，开启连接线程，进行数据的交互。
b.客户端模式：用户设置所要连接的服务器的IP地址和端口号，点击连接，开启连接线程，连接成功后，进行与木目标服务器的数据交互。
3.本demo还对交互数据进行了处理，可分为十六进制显示和ascll显示。加了一些自动自动发送，自动换行等的功能。
本项目所用的权限：
由于用到WIFI连接，以及IP的地址获取，要配置相应的权限：
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/><uses-permission android:name="android.permission.INTERNET"/><uses-permission android:name="android.permission.READ_PHONE_STATE" />
上代码的讲解吧：
首先是客户端的连接线程：Tcp_Client
代码如下：
package com.loumeng.TCP;import android.os.Handler;import android.os.Message;import android.util.Log;import java.io.IOException;import java.io.InputStream;import java.io.OutputStream;import java.net.InetAddress;import java.net.Socket;/** * Created by Administrator on 2017/2/15. */public class TCP_client extends Thread{ private static final String TAG_1 = "TCPChat"; private Handler mhandler; private Socket socket; private boolean isruning; public InputStream inputStream; public OutputStream outputStream; private InetAddress inetAddress; //IP地址 private int port; //端口号 public static int CLIENT_STATE_CORRECT_READ=7; public static int CLIENT_STATE_CORRECT_WRITE=8; //正常通信信息 public static int CLIENT_STATE_ERROR=9; //发生错误异常信息 public static int CLIENT_STATE_IOFO=10; //发送SOCKET信息 public TCP_client(Handler mhandler) { this.mhandler=mhandler; //传递handler对象用于与主线程的信息交互 isruning=true; } public void setInetAddress(InetAddress inetAddress) { this.inetAddress = inetAddress; } public void setPort(int port) { this.port = port; } @Override public void run() { if(socket == null){ try { Log.e(TAG_1,"启动连接线程"); socket=new Socket(inetAddress,port); new Receive_Thread(socket).start(); //启动接收线程 getadress(); } catch (IOException e) { e.printStackTrace(); senderror(); } } } public void getadress() //获取本地的IP地址和端口号{ String[] strings = new String[2]; strings[0]=socket.getInetAddress().getHostAddress(); strings[1]=socket.getInetAddress().getHostName(); Message message = mhandler.obtainMessage(CLIENT_STATE_IOFO,-1,-1,strings); mhandler.sendMessage(message); } public void close(){ if (socket !=null){ try { socket.close(); socket=null; isruning=false; } catch (IOException e) { } }else if (socket ==null){ Log.e(TAG_1, "未建立连接"); } } class Receive_Thread extends Thread{ private Socket msocket; public Receive_Thread (Socket msocket){ this.msocket =msocket; } @Override public void run() { try { while (isruning) { inputStream = msocket.getInputStream(); while (inputStream.available()==0){ } try { Thread.sleep(200); } catch (InterruptedException e) { e.printStackTrace(); } final byte[] buffer = new byte[1024];//创建接收缓冲区 final int len = inputStream.read(buffer);//数据读出来，并且数据的长度 mhandler.sendMessage(mhandler. obtainMessage(CLIENT_STATE_CORRECT_READ,len,-1,buffer)); } }catch (IOException e) { e.printStackTrace(); senderror(); }finally { if(msocket!=null){ try { msocket.close(); } catch (IOException e) { e.printStackTrace(); } } try { if(inputStream!=null){ inputStream.close(); } if (outputStream!=null){ outputStream.close(); } } catch (IOException e) { e.printStackTrace(); } Log.e(TAG_1,"关闭连接，释放资源"); } } } public void sendmessage(byte[] message){ try { outputStream =socket.getOutputStream(); mhandler.sendMessage(mhandler. obtainMessage(CLIENT_STATE_CORRECT_WRITE,-1,-1,message)); outputStream.write(message); } catch (IOException e) { senderror(); } } void senderror(){ mhandler.sendMessage(mhandler.obtainMessage(CLIENT_STATE_ERROR)); //发送连接的错误}}
接下来是服务器端的连接子线程 TCP_serveice.class
代码如下：
package com.loumeng.TCP;import android.os.Handler;import android.os.Message;import android.util.Log;import java.io.IOException;import java.io.InputStream;import java.io.OutputStream;import java.net.InetAddress;import java.net.ServerSocket;import java.net.Socket;/** * Created by Administrator on 2017/2/13. */public class TCP_service extends Thread{ private static final String TAG_1 = "TCPChat"; private Handler mhandler; private ServerSocket serverSocket; public InputStream Ser_inputStream; public OutputStream Ser_outputStream; private Socket Ser_Socket; private int mport; private boolean is_start =true; public static int SERVER_STATE_CORRECT_READ=3; public static int SERVER_STATE_CORRECT_WRITE=4; //正常通信信息 public static int SERVER_STATE_ERROR=5; //发生错误异常信息 public static int SERVER_STATE_IOFO=6; //发送SOCKET信息 public TCP_service(Handler mhandler,int mport){ this.mhandler=mhandler; this.mport=mport; } @Override public void run() { super.run(); try { serverSocket= new ServerSocket(mport); } catch (IOException e) { e.printStackTrace(); send_Error(); } try { while (is_start) { Log.e(TAG_1,"等待客户端连接 is_start="+ is_start); Ser_Socket=serverSocket.accept(); //开启监听 if(Ser_Socket!=null){ //启动接收线程 Receive_Thread receive_Thread = new Receive_Thread(Ser_Socket); //当有客户端连接时，开启数据接收的线程 receive_Thread.start(); } } }catch (IOException e) { e.printStackTrace(); send_Error(); // 发送错误 } } class Receive_Thread extends Thread { private Socket socket = null; public Receive_Thread(Socket socket) { this.socket = socket; getAddress(); try { Ser_inputStream = socket.getInputStream(); Ser_outputStream = socket.getOutputStream(); } catch (IOException e) { e.printStackTrace(); send_Error(); } } public void getAddress() { InetAddress inetAddress = socket.getInetAddress(); String[] strings = new String[2]; strings[0] = inetAddress.getHostAddress(); strings[1] = inetAddress.getHostName(); Message message = mhandler.obtainMessage(SERVER_STATE_IOFO, strings); mhandler.sendMessage(message); } @Override public void run() { super.run(); while (is_start) { try { while (Ser_inputStream.available() == 0) { } try { Thread.sleep(200); } catch (InterruptedException e) { e.printStackTrace(); } final byte[] buf = new byte[1024]; final int len = Ser_inputStream.read(buf); Message message = mhandler.obtainMessage(SERVER_STATE_CORRECT_READ, len, 1, buf); mhandler.sendMessage(message); } catch (IOException e) { e.printStackTrace(); send_Error(); } } try { if (Ser_inputStream != null) Ser_inputStream.close(); if (Ser_outputStream != null) Ser_outputStream.close(); if (socket != null) { socket.close(); socket = null; } Log.e(TAG_1, "断开连接监听 释放资源"); } catch (IOException e) { e.printStackTrace(); } } } public void close() { try { if (serverSocket != null) serverSocket.close(); if (Ser_Socket != null) Ser_Socket.close(); Log.e(TAG_1, "断开连接监听 关闭监听SOCKET"); } catch (IOException e) { e.printStackTrace(); } } //数据写入函数 public void write(byte[] buffer){ try { if (Ser_outputStream!=null){ Ser_outputStream.write(buffer); Message er_message = mhandler. obtainMessage(SERVER_STATE_CORRECT_WRITE,-1,-1,buffer); mhandler.sendMessage(er_message); }else{ send_Error();} } catch (IOException e) { e.printStackTrace(); send_Error(); } } public void send_Error(){ Message er_message = mhandler.obtainMessage(SERVER_STATE_ERROR); mhandler.sendMessage(er_message); } public void setis_start(boolean is_start) { this.is_start = is_start; }}主界面的主程序：TCP_chat.class,主要是对以上两个子线程的调用和对数据的交互和处理。代码如下：

接下来是数据处理的代码，涉及十六进制和ascll数据的转化
代码如下：
package com.loumeng.TCP;public class Data_syn { // 将字节数组转化为16进制字符串，确定长度 public static String bytesToHexString(byte[] bytes, int a) { String result = ""; for (int i = 0; i < a; i++) { String hexString = Integer.toHexString(bytes[i] & 0xFF);// 将高24位置0 if (hexString.length() == 1) { hexString = '0' + hexString; } result += hexString.toUpperCase(); } return result; } // 将字节数组转化为16进制字符串，不确定长度 public static String Bytes2HexString(byte[] b) { String ret = ""; for (int i =0; i < b.length; i++) { String hex = Integer.toHexString(b[i] & 0xFF);// 将高24位置0 if (hex.length() == 1) { hex = '0' + hex; } ret += hex.toUpperCase(); } return ret; } // 将16进制字符串转化为字节数组 public static byte[] hexStr2Bytes(String paramString) { int i = paramString.length() / 2; byte[] arrayOfByte = new byte[i]; int j = 0; while (true) { if (j >= i) return arrayOfByte; int k = 1 + j * 2; int l = k + 1; arrayOfByte[j] = (byte) (0xFF & Integer.decode( "0x" + paramString.substring(j * 2, k) + paramString.substring(k, l)).intValue()); ++j; } }} 主界面布局 文件ly_tcpchat.xml文件

总结：
这个项目总的来说是比较简单的，解释涉及Java socket的通信，不管是作为服务器或者客户端，都是socket在通信。侧滑界面的设置和使用，网上资料很多，这这里就不一一解释说明了。代码上去弄得比较繁琐，学习做的东西，还请各位请见谅，有什么意见和想法，欢迎留言，一起共同努力。
