请试一试。

public void callWebService()
{  
    HttpPost postMethod = new HttpPost("Your Url");
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();

    nameValuePairs.add(new BasicNameValuePair("username","your user name");
    nameValuePairs.add(new BasicNameValuePair("password","your password");
    postMethod.setEntity(new UrlEncodedFormEntity(nameValuePairs));
    DefaultHttpClient hc = new DefaultHttpClient();

    HttpResponse response = hc.execute(postMethod);
    HttpEntity entity = response.getEntity();

    if (entity != null) 
    {
            InputStream inStream = entity.getContent();
            result= Utility.convertStreamToString(inStream);
            Log.i("---------------- Result",result);
    }
} // end callWebService()

public static String convertStreamToString(InputStream is)
{
   BufferedReader reader = new BufferedReader(new InputStreamReader(is));
   StringBuilder sb = new StringBuilder();

   String line = null;
   try 
   {
       while ((line = reader.readLine()) != null) 
       {
           sb.append(line + "\n");
       }
   } 
   catch (IOException e) 
   {
       e.printStackTrace();
   } 
   finally 
   {
       try 
       {
           is.close();
       } 
       catch (IOException e) 
       {
           e.printStackTrace();
       }
   }
   return sb.toString();

}
