Android app與PC端交互

app提交信息到PC端mysql數據庫

新建名爲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);
    }
    /*發起HTTP請求*/
    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 {
        /*將username和password傳給Tomcat服務器*/
        url=url+"?name="+name;
        try {
            URL httpUrl = new URL(url);
            /*獲取網絡鏈接*/
            HttpURLConnection conn = (HttpURLConnection) httpUrl.openConnection();
            /*設置請求方法爲GET方法*/
            conn.setRequestMethod("GET");
            /*設置訪問超時時間*/
            conn.setReadTimeout(5000);
            BufferedReader reader=new BufferedReader(new InputStreamReader(conn.getInputStream()));
            String str;
            StringBuffer sb=new StringBuffer();
            //讀取服務器返回的信息
            while((str=reader.readLine())!=null)
            {
                sb.append(str);
            }
            //把服務端返回的數據打印出來
            System.out.println("result"+sb.toString());
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

    /*在run中調用doGet*/
    @Override
    public void run() {
        try {
            doGet();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

佈局文件activity_sign.xml

本身搭一個Tomact服務器，把SignActivity裏的url換成本身的就OK了
