どのようにアンドロイドで安らかなWebサービスを呼び出す

Question

誰でも私は安らかなWebサービスに認証の詳細を投稿し、それから応答を得る方法を手伝ってくれます。 私はUsername、IsAuthenticated（すなわちtrueまたはfalse）、Password.Alsoもurlエンコーディング方法について説明する必要があります。 以下に私のコードを示しました。私はAndroidの初心者です。

public class LoginActivity extends Activity 
{ 
    String Username; 
    String Password; 
    String IsAuthenticated; 
    String answer; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.main); 
      try { 
       POST(Username,Password,IsAuthenticated); 
      } catch (Exception e) { 
       e.printStackTrace(); 
      } 
     } 


    public String POST(String Username, String IsAuthenticated, String Password) { 
     String Returned = null; 
      HttpClient httpclient = new DefaultHttpClient(); 
      HttpPost httppost = new HttpPost("http://......./Authenticate"); 

      try { 
      List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2); 
      // Your DATA 
      nameValuePairs.add(new BasicNameValuePair("UserName", "Username")); 
      nameValuePairs.add(new BasicNameValuePair("IsAuthenticated", "false")); 
      nameValuePairs.add(new BasicNameValuePair("Password", "Password")); 

      httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs, HTTP.UTF_8)); 
      HttpResponse response = httpclient.execute(httppost); 
      HttpEntity resEntity = response.getEntity(); 
      Returned = EntityUtils.toString(resEntity); 

      System.out.println(Returned); 
      Toast.makeText(this, Returned, Toast.LENGTH_LONG).show(); 
      } catch (ClientProtocolException e) { 
      Toast.makeText(this, "There was an issue Try again later", Toast.LENGTH_LONG).show(); 
      } catch (IOException e) { 
      Toast.makeText(this, "There was an IO issue Try again later", Toast.LENGTH_LONG).show(); 
      e.printStackTrace(); 
      } 

      return Returned; 
     } 
}

私は最後に答えを得て、うまく働いています...下記の作業コードを掲載しました。

public class LoginActivity extends Activity 
{ 
    String Returned; 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.main); 

      try { 
       HttpClient httpclient = new DefaultHttpClient(); 
       HttpPost post = new HttpPost("http://Your url here/"); 
       StringEntity str = new StringEntity("Your xml code"); 
       str.setContentType("application/xml; charset=utf-8"); 
       str.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"application/xml; charset=utf-8")); 
       post.setEntity(str); 
       HttpResponse response = httpclient.execute(post); 
       HttpEntity entity = response.getEntity(); 
       Returned = EntityUtils.toString(entity); 
       Toast.makeText(this, Returned, Toast.LENGTH_LONG).show(); 
      } catch (IOException ioe) { 
      ioe.printStackTrace(); 
      } 
      } 
} 

ありがとうございました。
