Android客户端与电脑服务器端

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>
