This is the example response xml:

I solve it. I added this code. it’s working.

my Code

@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;
