这是服务端代码

import java.io.DataOutputStream;
import java.io.FileInputStream;
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;

public class Server01 {
public static void main(String[] args) {
try {
ServerSocket server = new ServerSocket(30000);
Socket socket = server.accept();
DataOutputStream dos = new DataOutputStream(socket.getOutputStream());
FileInputStream fis = new FileInputStream("C:/sunnyTest/picture/cat01.jpg");
int size = fis.available();

System.out.println("size = "+size);
byte[] data = new byte[size];
fis.read(data);
dos.writeInt(size);
dos.write(data);

dos.flush();
dos.close();
fis.close();
socket.close();
server.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}

这里是客户端代码

import com.login.R;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.Bitmap.CompressFormat;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;

public class TestActivity extends Activity {

private ImageView imageView = null;
private Bitmap bmp = null;

private ImageView imageView02;
private Bitmap bmp02;
private Button button02;
private String uploadFile="/mnt/sdcard/qt.png";

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.image);

imageView = (ImageView) findViewById(R.id.image01);
Button btn = (Button) findViewById(R.id.Button01);
btn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {

Socket socket = null;
try {
socket = new Socket("192.168.1.203", 30000);
DataInputStream dataInput = new DataInputStream(socket.getInputStream());
int size = dataInput.readInt();
byte[] data = new byte[size];
int len = 0;
while (len < size) {
len += dataInput.read(data, len, size - len);
}
ByteArrayOutputStream outPut = new ByteArrayOutputStream();
bmp = BitmapFactory.decodeByteArray(data, 0, data.length);
bmp.compress(CompressFormat.PNG, 100, outPut);
imageView.setImageBitmap(bmp);

//Bitmap bitmap = BitmapFactory.decodeStream(dataInput);
//myHandler.obtainMessage().sendToTarget();
} catch (IOException e) {
e.printStackTrace();
}
finally {
try {
socket.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
});
}
}
客户端向服务端发送图片的代码:

服务端:
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.FileInputStream;
import java.io.IOException;
import java.net.InetSocketAddress;
import java.net.ServerSocket;
import java.net.Socket;
public class Server02 {
public static void main(String[] args) {
try {
ServerSocket server = new ServerSocket(40000);
Socket socket = server.accept();
DataInputStream dos = new DataInputStream(socket.getInputStream());
int len = dos.available();
System.out.println("len = "+len);
byte[] data = new byte[len];
dos.read(data);

System.out.println("data = "+data);
dos.close();
socket.close();
server.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
客户端:
private String url = "http://www.yszaixian.cn"
imageView02 = (ImageView)findViewById(R.id.image02);
button02 = (Button)findViewById(R.id.Button02);
button02.setOnClickListener(new OnClickListener(){
public void onClick(View arg0) {
Socket socket;
try {
socket = new Socket("192.168.1.203",40000);
DataOutputStream out = new DataOutputStream(socket.getOutputStream());

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.qt);
imageView02.setImageBitmap(bitmap);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
//读取图片到ByteArrayOutputStream
bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] bytes = baos.toByteArray();
out.write(bytes);

System.out.println("bytes--->"+bytes);
out.close();
socket.close();
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
});
