最近在做你画我猜。。。。使用socket传递对象，下面的代码如果是java程序的话是没问题的，但是改到android下却有问题了在server 端提示，而且我在服务端也定义了这个Data类的。
java.lang.ClassNotFoundException: com.DrawAndGuess.Data class not found
其中 com.DrawAndGuess.Data的代码如下
- Java code
package com.DrawAndGuess;import java.io.Serializable;public class Data implements Serializable{ private int x,y; Data(int x,int y){ this.x = x; this.y = y; } public int getX() { return x; } public void setX(int x) { this.x = x; } public int getY() { return y; } public void setY(int y) { this.y = y; } private static final long serialVersionUID = 1L; }- Java code
package com.DrawAndGuess;import java.io.ObjectInputStream;import java.io.ObjectOutputStream;import java.io.Serializable;import java.net.Socket;import android.app.Activity;import android.content.Context;import android.graphics.Canvas;import android.graphics.Color;import android.graphics.Paint;import android.os.Bundle;import android.view.MotionEvent;import android.view.SurfaceHolder;import android.view.SurfaceView;public class DrawAndGuessActivity extends Activity { DrawAndGuessSurfaceView drawAndGuessSurfaceView; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); drawAndGuessSurfaceView = new DrawAndGuessSurfaceView(this); setContentView(drawAndGuessSurfaceView); try{ Data data = new Data(3,4); Socket socketConnection = new Socket("172.18.43.59",8889); ObjectOutputStream clientOutStream = new ObjectOutputStream(socketConnection.getOutputStream()); ObjectInputStream clientInputStream = new ObjectInputStream(socketConnection.getInputStream()); System.out.println("connect...."); clientOutStream.writeObject(data); data = (Data) clientInputStream.readObject(); System.out.println("Receive from server:"); System.out.println("x: "+ data.getX() + "y: " + data.getY()); clientOutStream.close(); clientInputStream.close(); }catch (Exception e) { // TODO: handle exception e.printStackTrace(); } } }服务器如下
- Java code
package testsocket.com;import java.io.ObjectInputStream;import java.io.ObjectOutputStream;import java.io.Serializable;import java.net.ServerSocket;import java.net.Socket;public class Server { public static void main(String[] arg) { Data data = null; try{ ServerSocket socketConnection = new ServerSocket(11111); System.out.println("Server waiting"); Socket pipe = socketConnection.accept(); ObjectInputStream serverInputStream = new ObjectInputStream(pipe.getInputStream()); ObjectOutputStream serverOutputStream = new ObjectOutputStream(pipe.getOutputStream()); data = (Data) serverInputStream.readObject(); System.out.println("Receive from client:"); System.out.println("x: "+ data.getX() + "y: " + data.getY()); data.setX(5); data.setY(6); serverOutputStream.writeObject(data); serverInputStream.close(); serverOutputStream.close(); System.out.println("server receive"); }catch (Exception e) { // TODO: handle exception e.printStackTrace(); } } }
