我调用我的web服务并使用回调制作动态代码。最初我发送响应字符串但是我正在使用gjson库，这对我不起作用。现在我发送

RequestTask类
public class RequestTask extends AsyncTask<String, String, InputStream>{
private WebserviceCallBack callBack;
private ProgressDialog progressDialog;
@Override
protected void onPreExecute() {
// TODO Auto-generated method stub
progressDialog= new ProgressDialog((Context) callBack);
super.onPreExecute();
progressDialog.setTitle("Please Wait...");
progressDialog.setMessage("Webservice Call...");
progressDialog.setCancelable(true);
progressDialog.show();
}
@Override
protected InputStream doInBackground(String... uri) {
HttpClient httpclient = new DefaultHttpClient();
HttpResponse response;
String responseString = null;
try {
response = httpclient.execute(new HttpGet(uri[0]));
StatusLine statusLine = response.getStatusLine();
if(statusLine.getStatusCode() == HttpStatus.SC_OK){
/*Reader reader = new InputStreamReader(response.getEntity().getContent());
Gson gson = new Gson();
Holder response1 = gson.fromJson(reader, Holder.class);

responseString = out.toString();*/
return response.getEntity().getContent();
} else{
//Closes the connection.
response.getEntity().getContent().close();
throw new IOException(statusLine.getReasonPhrase());
}
} catch (ClientProtocolException e) {
//TODO Handle problems..\
progressDialog.hide();
} catch (IOException e) {
//TODO Handle problems..
progressDialog.hide();
}
return null;
}
@Override
protected void onPostExecute(InputStream result) {
super.onPostExecute(result);
//Do anything with response..
if(callBack!=null){
callBack.getWebserviceResponse(result);
}
progressDialog.dismiss();
progressDialog=null;
}
public void setObserver(WebserviceCallBack callback){
callBack=callback;
}
}
and **call back** like that
public interface WebserviceCallBack {
public void getWebserviceResponse(InputStream result);
}
and **main activity** like that
public class Appliacationload extends Activity implements WebserviceCallBack{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.appliacationload);
/*WebserviceMethod callDepartudeDashboard=new WebserviceMethod();
callDepartudeDashboard.setObserver(this);
callDepartudeDashboard.getwebService(ConstantVariable.dashboardWebServiceURL+"a/"+"arrival"+"?crsCode=hnh");*/
RequestTask callWebService=new RequestTask();
callWebService.setObserver(this);
callWebService.execute(ConstantVariable.dashboardWebServiceURL+"a/"+"arrival"+"?crsCode=vic");
}
@Override
public void getWebserviceResponse(InputStream result) {
// TODO Auto-generated method stub
Reader reader = new InputStreamReader(result);
Gson gson = new Gson();
Holder response1 = gson.fromJson(reader, Holder.class);
Log.d("-----", "pallavi");
}
持有人类;
public class Holder {
List<deparaturedaseboarddto> data;
}
我可以发送响应字符串而不是使用gson库吗？
