我有 asynctask 类，我在其中执行使用 web 服务并解析响应。解析后我得到列表<>。我怎样才能通过我的其他班级？

这是我的异步任务类

String response;
    List<Item> lstresponse_locations = null;
//  CustomAdapter CustAdapter;
//  List<Item> lstresult = new ArrayList<Item>();
//  ListView lstcities;



//  String params;
    @Override
    protected String doInBackground(String... params) {
        // TODO Auto-generated method stub\

        SendRequesttoServer(params);
        return response;
    }

    @Override
    protected void onPostExecute(String result) {
        // TODO Auto-generated method stub
        super.onPostExecute(result);


    }

    @Override
    protected void onPreExecute() {
        // TODO Auto-generated method stub
        super.onPreExecute();
    }

// getting response from webservice

    public void SendRequesttoServer(String[] params) {

        try {

        SOAP_ACTION = NAMESPACE + METHOD;
        SoapObject request = new SoapObject(NAMESPACE, METHOD);
        request.addProperty("CityName", params[0]);

        SoapSerializationEnvelope res = new SoapSerializationEnvelope(
                    SoapEnvelope.VER11);
        res.dotNet = true;
        res.setOutputSoapObject(request);

        HttpTransportSE call = new HttpTransportSE(url);

        SoapPrimitive result;
        call.call(SOAP_ACTION, res);
        result = (SoapPrimitive) res.getResponse();
        ParseLocations Objparselocations = new ParseLocations(
                    new ByteArrayInputStream(result.toString()
                            .getBytes("UTF-8")));
        lstresponse_locations = Objparselocations.parse();

        response = lstresponse_locations.toString();
            // lstCities.toArray();

        System.out.println(lstresponse);
    } catch (SoapFault e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
    e.printStackTrace();
    } catch (XmlPullParserException e) {
        // TODO Auto-generated catch block
    e.printStackTrace();
    }

    }
}

我怎样才能通过响应？谢谢 ramu

Try to override the onPostExecute in you activity itself and create a adapter object inside of the onPostExecute and set the adapter to your listview like

Class MyActivity extends Activity {

    public void onCreate(Bundle args) {
     ......
     ......
     new MyAsyncTask() {

       public void onPostExecute(List<Object> list) {
          listView.setAdapter(new MyAdapter(list));
       }

     }.execute(params);
     .......
     ........
   }
}

Edit : In your AsyncTask class make the third parameter as List like

class MyAsync extends AsycnTask<String, Integer, List<Object>>

just pass your ListView and its Adapter to the AsyncTask in the constructor, set the Adapter in the onPostExecute() method. Worked fine for me

字符串由 doInBackground 返回以发布执行，因此 postExceute 中的结果是您的响应

  protected void onPostExecute(String result) {
                // TODO Auto-generated method stub
                super.onPostExecute(result);
Log.d("Response: ",result);

}
