使用android請求本地主機中的php頁面的http請求

我正在創建一個需要與本地web服務器（WAMP）交互的android應用程序。 WAMP有一個PHP文件，只是回聲你好世界。此應用程序請求此頁面，但是當我運行應用程序並單擊觸發請求事件的按鈕時，在EditText上沒有打印出Helloworld的結果。以下是代碼：使用android請求本地主機中的php頁面的http請求

package com.mobilevoter; 

import java.io.BufferedReader; 
import java.io.IOException; 
import java.io.InputStream; 
import java.io.InputStreamReader; 
import java.net.URLConnection; 

import org.apache.http.HttpEntity; 
import org.apache.http.HttpResponse; 
import org.apache.http.client.HttpClient; 
import org.apache.http.client.methods.HttpPost; 
import org.apache.http.impl.client.DefaultHttpClient; 

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

public class mobilevoter extends Activity implements OnClickListener { 
    Button proceed; 
    EditText voter_number; 
    EditText id_number; 
    URLConnection conn; 
    BufferedReader myreader; 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     proceed=(Button)findViewById(R.id.proceed_btn); 
     voter_number=(EditText)findViewById(R.id.editText_voternumber); 
     id_number=(EditText)findViewById(R.id.editText_idnumber); 
     proceed.setOnClickListener(this); 
    } 
    @Override 
    public void onClick(View src) { 

      if(src==proceed){ 
       HttpClient authenticationClient= new DefaultHttpClient(); 
       HttpPost url_post=new HttpPost("http://10.0.2.2/practice/index.php"); 
       HttpResponse response; 
       try 
       { 
       response=authenticationClient.execute(url_post); 
       HttpEntity authenticationEntity=response.getEntity(); 
       InputStream authenticationStream=authenticationEntity.getContent(); 
       BufferedReader myreader=new BufferedReader(new InputStreamReader(authenticationStream)); 
       String inputStream; 
       while((inputStream=myreader.readLine())!=null) 
       { 
        voter_number.setText(inputStream); 
       } 
       } 
       catch(Exception exception) 
       { 
        System.out.println(exception.getMessage()); 
       } 
       /*finally 
       { 
        try 
        { 
        myreader.close(); 
        } 
        catch(IOException ioexception) 
        { 
         System.out.println(ioexception.getMessage()); 
        } 
       }*/ 

      } 
    } 
}

清單如下所示：

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
     package="com.mobilevoter" 
     android:versionCode="1" 
     android:versionName="1.0"> 
    <application android:icon="@drawable/icon" android:label="@string/app_name"> 
     <activity android:name=".mobilevoter" 
        android:label="@string/app_name"> 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 
       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 
    </application> 
    <uses-permission android:name="android.permission.INTERNET" /> 
</manifest>

我會很感激的幫助。感謝名單。
