手机端：

package zhanghua.test.dataexchange;

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.net.HttpURLConnection;
import java.net.URL;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

public class DataExchange extends Activity {
private EditText titleText;
private EditText bodyText;

@Override
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.note_edit);

titleText = (EditText) findViewById(R.id.title);
bodyText = (EditText) findViewById(R.id.body);

Button confirmButton = (Button) findViewById(R.id.confirm);

confirmButton.setOnClickListener(new View.OnClickListener() {

public void onClick(View arg0) {
// Bundle bundle = new Bundle();
// bundle.putString(Notepadv3.KEY_TITLE,
// titleText.getText().toString());
// bundle.putString(Notepadv3.KEY_BODY,
// bodyText.getText().toString());
// if (rowId != null) {
// bundle.putLong(Notepadv3.KEY_ROW_ID, rowId);
// }
// setResult(RESULT_OK, null, bundle);
// finish();

String u = "http://172.17.1.122:8083/ServerApp/ServletApp ";
URL url = null;
HttpURLConnection httpurlconnection = null;
try {
url = new URL(u);
httpurlconnection = (HttpURLConnection) url
.openConnection();
httpurlconnection.setDoOutput(true);
httpurlconnection.setRequestMethod("POST");
// httpurlconnection.setRequestProperty("Content-Language","en-CA");
// httpurlconnection.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
// httpurlconnection.setRequestProperty("Connection","Keep-Alive");
// //始终使用同一个HTTP连接来多次传递数据
// 手机传给电脑的数据
DataOutputStream dos = new DataOutputStream(
httpurlconnection.getOutputStream());
dos.writeUTF(titleText.getText().toString());
dos.writeUTF(bodyText.getText().toString());
dos.flush();
dos.close();
// httpurlconnection.getOutputStream().flush();
// httpurlconnection.getOutputStream().close();
int code = httpurlconnection.getResponseCode();
System.out.println("code " + code);

// 接收servlet响应数据
DataInputStream dis = new DataInputStream(httpurlconnection
.getInputStream());
String return1Str = dis.readUTF();
String return2Str = dis.readUTF();
System.out.println("手机接收到servlet端传来的第一个参数为:" + return1Str);
titleText.setText(return1Str); // 显示
// 主要起调试的作用，调试的结果将显示在WTK的控制台中
System.out.println("手机接收到servlet端传来的第二个参数为:" + return2Str);
bodyText.setText(return2Str); // 显示
} catch (Exception e) {
e.printStackTrace();
} finally {
if (httpurlconnection != null)
httpurlconnection.disconnect();
}

}

});
}
}

2、电脑端

package quqi;

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStream;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**

*/
public class ServletApp extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
response.setContentType("text/html; charset=GBK");

// 设置响应属性
// 接收客户端的请求
InputStream is = request.getInputStream();
DataInputStream dis = new DataInputStream(is);
String tf1Str = dis.readUTF();
String tf2Str = dis.readUTF();
System.out.println("servlet端接收到手机传来的第一个参数为：" + tf1Str);
// 主要起调试的作用，调试的结果显示在tomcat的启动DOS窗口中
System.out.println("servlet端接收到手机传来的第二个参数为：" + tf2Str);
// 对接收的参数进行处理
String return1Str = tf1Str.concat(":早上好!");
// 在接收到的参数后连接字符串
String return2Str = tf2Str.concat(":晚上好!");
// 发送处理后的参数给手机
DataOutputStream dos = new DataOutputStream(response.getOutputStream());
dos.writeUTF(return1Str);
dos.writeUTF(return2Str);
System.out.println("servlet传递给手机的第一个参数为:" + return1Str);
System.out.println("servlet传递给手机的第二个参数为:" + return2Str);
}

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request, response);
}

public void destroy() {
}
// 清除资源
}
