檢查下面的示例表它應該工作

@Override 
protected void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    init(); 
} 
private void init() 
{ 
    //your webservice envelope 
    String envelope="<?xml version=\"1.0\" encoding=\"utf-8\"?><soap:Envelope  xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\"><soap:Body><GetContentTreeBySections xmlns=\"http://tempuri.org/\"><SectionsInclude>%s</SectionsInclude><DocumentCount>%s</DocumentCount><SortBy>%s</SortBy><SortOrder>%s</SortOrder><UserName>%s</UserName><Pass>%s</Pass></GetContentTreeBySections></soap:Body></soap:Envelope>"; 

String myEnvelope = String.format(envelope, "myParam1 value", "myParam2 value","myParam3 value","myParam4 value"); 
String url = "http://www.mywebserice.com/XMLGenerator/GenerateXML.asmx"; 
String soapAction = "http://tempuri.org/GetContentTreeBySections"; 
String response = CallWebService(url, soapAction, myEnvelope); 
//Log.v("response", response); 
Toast.makeText(getApplicationContext(), "this"+response,Toast.LENGTH_LONG).show(); 
String xml=response;  
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) 
{ 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.activity_main, menu); 
    return true; 
} 
    String CallWebService(String url,String soapAction,String envelope) 
{ 

    final DefaultHttpClient httpClient=new DefaultHttpClient(); 
    // request parameters 
    HttpParams params = httpClient.getParams(); 
    HttpConnectionParams.setConnectionTimeout(params, 10000); 
    HttpConnectionParams.setSoTimeout(params, 15000); 
    // set parameter 
    HttpProtocolParams.setUseExpectContinue(httpClient.getParams(), true); 

    // POST the envelope 
    HttpPost httppost = new HttpPost(url); 
    // add headers 
    httppost.setHeader("soapaction", soapAction); 
    httppost.setHeader("Content-Type", "text/xml; charset=utf-8"); 
    String responseString=""; 

    try 
    { 
      // the entity holds the request 
      HttpEntity entity = new StringEntity(envelope); 
      httppost.setEntity(entity); 

      // Response handler 
      ResponseHandler<String> rh=new ResponseHandler<String>() { 
    // invoked when client receives response 
    public String handleResponse(HttpResponse response) 
     throws ClientProtocolException, IOException { 

    // get response entity 
    HttpEntity entity = response.getEntity(); 

    // read the response as byte array 
      StringBuffer out = new StringBuffer(); 
      byte[] b = EntityUtils.toByteArray(entity); 

      // write the response byte array to a string buffer 
      out.append(new String(b, 0, b.length)); 
      return out.toString(); 
    } 
    }; 

    responseString=httpClient.execute(httppost, rh); 

    } 
    catch (Exception e) { 
     Log.v("exception", e.toString()); 
    } 

    // close the connection 
    httpClient.getConnectionManager().shutdown(); 
    return responseString; 
}
