Android客户端与计算机服务器端

电脑服务器端

import java.io.*;import java.net.ServerSocket;import java.net.Socket;import java.util.*;public class MyServer {	public static void main(String[] args) throws Exception{		ServerSocket server=new ServerSocket(1000);		Socket clink=server.accept();		PrintStream out=new PrintStream(clink.getOutputStream());		BufferedReader in=new BufferedReader(new InputStreamReader(clink.getInputStream()));		StringBuffer bu=new StringBuffer();		bu.append("Andorid: ");		bu.append(in.readLine());		out.println(bu);				in.close();		out.close();		clink.close();		server.close();	}}

Andorid客户端

第一步：main.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >         <Button        android:id="@+id/send"         android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="连接ServerSocket程序" />    <TextView        android:id="@+id/info"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="等待程序的连接" /></LinearLayout>

第二步：编写JAVA 类

package com.android.main;import java.io.BufferedReader;import java.io.InputStreamReader;import java.io.PrintStream;import java.net.Socket;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.TextView;public class ActivityMain extends Activity {	private Button button;	private TextView textView;    public void onCreate(Bundle savedInstanceState) {           	super.onCreate(savedInstanceState);        setContentView(R.layout.main);        button=(Button)this.findViewById(R.id.send);        textView=(TextView)this.findViewById(R.id.info);        button.setOnClickListener(new SendOnclickListener());    }    class SendOnclickListener  implements OnClickListener {    			public void onClick(View v) {			try{				Socket clink=new Socket("10.10.104.57",1000);				PrintStream out=new PrintStream(clink.getOutputStream());				BufferedReader in=new BufferedReader(new InputStreamReader(clink.getInputStream()));				out.println("发送信息给ServerSocket");				ActivityMain.this.textView.setText(in.readLine());								in.close();				out.close();				clink.close();							}			catch(Exception e){							}					}    	    }}

第三步：添加Internet权限

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.android.main"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk android:minSdkVersion="10" />    <uses-permission android:name="android.permission.INTERNET"/><!-- 添加Internet权限 -->    <application        android:icon="@drawable/ic_launcher"        android:label="@string/app_name" >        <activity            android:name=".ActivityMain"            android:label="@string/app_name" >            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>    </application></manifest>
