两个安卓手机的链接socket（套接字）编程
偶然希望两个安卓手机能交互一下，所以写了两个安卓之间交互的程序，好吧我承认是从java socket套用过来的，但是，还是有点改变。。。。。。。
两个手机，一个做server，一个做client
首先是第一个server的：
主类：
public class MainActivity extends Activity {
TextView qwe = null;
static Toast tt = null;
PrintWriter out ;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
qwe = (TextView)findViewById(R.id.qwe);
/*静态的吐司，方便收到信息后其他线程调用*/
tt = Toast.makeText(MainActivity.this, "qe", Toast.LENGTH_SHORT);
OpenConnection();
}
public void OpenConnection(){
try {
ServerSocket s = new ServerSocket(6666);
//System.out.println("服务器端------监听中.....");
Socket socket = s.accept();
//System.out.println("开始：" + socket);
GetMessage gm = new GetMessage(socket,this);
out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())), true);
Thread gt = new Thread(gm);
gt.start();
} catch (IOException e1) {
e1.printStackTrace();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
menu.add(0,0,0,"PRINT");
return true;
}
@Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
out.println("asdasd");//当点击的时候，就会发送出去字符串
out.flush();
return super.onMenuItemSelected(featureId, item);
}
}
发信的线程类：
public class SendMessage implements Runnable {
PrintWriter out;
BufferedReader is;
public SendMessage(Socket socket) throws IOException
{
out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())), true);
is = new BufferedReader(new InputStreamReader(System.in));
}
public void run()
{
String input = new String();
while (true)
{
try
{
input = is.readLine().trim();
}
catch (IOException e)
{
e.printStackTrace();
}
out.println(input);
System.out.print("服务器说：");
out.flush();
}
}
}
收信的线程类：
package com.example.serve;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.Socket;
public class GetMessage implements Runnable{
BufferedReader in;
MainActivity context;
public GetMessage(Socket socket,MainActivity context)
{
try
{
this.context = context;
in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
}
catch (IOException e)
{
e.printStackTrace();
}
}
public void run()
{
String str = "";
while (true)
{
try
{
str = in.readLine();
}
catch (IOException e)
{
e.printStackTrace();
}
if (str.equals("q"))
{
break;
}
if(str!=null)
{
System.out.print("客户端回应说:" + str);
MainActivity.tt.show();
}
}
}
}
然后是第二个client的手机程序：
public class MainActivity extends Activity {
TextView tv = null;
CGetMessage gm;
CSendMessage sm;
PrintWriter out ;
static Toast tt = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv = (TextView)findViewById(R.id.asd);
tt = Toast.makeText(MainActivity.this, "qe", Toast.LENGTH_SHORT);
}
public void Open(){
try {
System.out.println("客户端!!" );
InetAddress addr = InetAddress.getByName("192.168.43.xx");//ip地址自己个性化
Socket socket = new Socket(addr, 6666);
System.out.println("客户端发出socket=" + socket);
out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())), true);
gm = new CGetMessage(socket);
System.out.println("你好");
sm = new CSendMessage(socket);
Thread gt = new Thread(gm);
gt.start();
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
menu.add(0,0,0,"yiqi");
menu.add(0,1,1,"ni");
return true;
}
@Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
if(item.getItemId() == 0){
out.println("yiqi");
out.flush();
}
else{
Open();
//out.println("ni");
//out.flush();
}
return super.onMenuItemSelected(featureId, item);
}
}
然后同样是收信的类：
public class CGetMessage implements Runnable {
private Socket socket;
BufferedReader in;
public CGetMessage(Socket socket)
{
this.socket = socket;
}
public void run()
{
BufferedReader in;
String str = "";
while (true)
{
try
{
in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
str = in.readLine();
}
catch (IOException e)
{
e.printStackTrace();
}
if(str!=null){
System.out.println("服务器回应说：" + str);
MainActivity.tt.show();
}
}
}
}
然后是发信的类：
public class CSendMessage implements Runnable {
PrintWriter out;
BufferedReader is;
public CSendMessage(Socket socket) throws IOException
{
out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())), true);
//is是读入的字符串
//is = new BufferedReader(new InputStreamReader(System.in));
}
public void run()
{
String input = new String();
while (true)
{
try
{
input = is.readLine().trim();
}
catch (IOException e)
{
e.printStackTrace();
}
out.println(input);
System.out.print("客户端说：");
out.flush();
}
}
}
注意，两个程序需要安装在两个手机上（话说没人会傻到安到一个手机上吧），然后互相链接热点。。。今天的更新完毕
