如何将数据发送到PHP服务器并接收数据到Android

Question

我在机器人编程新手，我想发送的数据到PHP服务器并接收数据的Android

展现，但我不知道创建它，我不是没有使用图书馆？并且可以举一些例子让我练习一下。

ps。对不起，我的英语不好。

例如Myphp “xxx.xxx.x.x/api.php”

$keyword = $_GET['keyword']; 
$index= $_GET['index']; 
$path = "http://xxxxxxx/webservice/&query=".urlencode($keyword)."&index=".$index.""; 
      $jsondata = file_get_contents($path); 
      $jsons = json_decode($jsondata,true); 

      echo json_encode($jsons); 

我想从EditText上发送keyword和index到PHP服务器并接收JSON数据显示列表视图。

HttpURLConnection类可用于获取，PUT，POST，DELETE请求：

try { 
       // Construct the URL 
    URL url = new URL("http://xxxxxxx/webservice/&query=" 
    +keyword.getText().toString() 
    +"&index="+index.getText().toString()); 
    // Create the request 
      urlConnection = (HttpURLConnection) url.openConnection(); 
      urlConnection.setRequestMethod("GET"); 
      urlConnection.connect(); 
    // Read the input stream into a String 
      InputStream inputStream = urlConnection.getInputStream(); 
      StringBuffer buffer = new StringBuffer(); 
      if (inputStream == null) { 
       // Nothing to do. 
       return null; 
      } 
      reader = new BufferedReader(new InputStreamReader(inputStream)); 

      String line; 
      while ((line = reader.readLine()) != null) { 
       // Since it's JSON, adding a newline isn't necessary (it won't affect parsing) 
       // But it does make debugging a *lot* easier if you print out the completed 
       // buffer for debugging. 
       buffer.append(line + "\n"); 
      } 

      if (buffer.length() == 0) { 
       // Stream was empty. No point in parsing. 

      } 
      JsonStr = buffer.toString(); //result 
} catch (IOException e) { 
} 

其中keyword和index将是你的EditText变量。
