Android app与PC端交互

app提交信息到PC端mysql数据库

新建名为SignActivity

package com.example.administrator.success;

import android.app.Activity;

import android.os.Bundle;

import android.view.View;

import android.widget.Button;

import android.widget.EditText;

public class SignActivity extends Activity {

    private EditText name;

//    private EditText password;

    private Button signup;

    @Override

    protected void onCreate(Bundle savedInstanceState)

    {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_sign);

        name=(EditText) findViewById(R.id.etSgAccount);

//        password=(EditText) findViewById(R.id.etSgPassword);

        signup=(Button) findViewById(R.id.btnSign);

    }

    /*发起HTTP请求*/

    public void onLogin(View v)

    {

        String url="http://182.92.66.60:8083/saveTestApp.jsp";

        new HttpThread(url, name.getText().toString()).start();

    }

}

HttpThread

package com.example.administrator.success;

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

import java.net.HttpURLConnection;

import java.net.MalformedURLException;

import java.net.URL;

import android.R.string;

public class HttpThread extends Thread {

    String url;

    String name;

//    String password;

    public HttpThread(String url, String name) {

        // TODO Auto-generated constructor stub

        this.url = url;

        this.name = name;

//        this.password = password;

    }

    private void doGet() throws IOException {

        /*将username和password传给Tomcat服务器*/

        url=url+"?name="+name;

        try {

            URL httpUrl = new URL(url);

            /*获取网络连接*/

            HttpURLConnection conn = (HttpURLConnection) httpUrl.openConnection();

            /*设置请求方法为GET方法*/

            conn.setRequestMethod("GET");

            /*设置访问超时时间*/

            conn.setReadTimeout(5000);

            BufferedReader reader=new BufferedReader(new InputStreamReader(conn.getInputStream()));

            String str;

            StringBuffer sb=new StringBuffer();

            //读取服务器返回的信息

            while((str=reader.readLine())!=null)

            {

                sb.append(str);

            }

            //把服务端返回的数据打印出来

            System.out.println("result"+sb.toString());

        } catch (MalformedURLException e) {

            // TODO Auto-generated catch block

            e.printStackTrace();

        }

    }

    /*在run中调用doGet*/

    @Override

    public void run() {

        try {

            doGet();

        } catch (IOException e) {

            // TODO Auto-generated catch block

            e.printStackTrace();

        }

    }

}

自己搭一个Tomact服务器，把SignActivity里的url换成自己的就OK了
