我ClassCastException在这一行进入 Logcat：Standort standort = (Standort) response;

从这段代码：

private void loadLocationMenuList() {
    ServiceProxy.createWebServiceTask(getActivity(), new RemoteCallListener() {

            @Override
        public void onRemoteCallError(String response) {
            // TODO Auto-generated method stub

       }

        @Override
        public void onRemoteCallComplete(Object response) {
            Log.d("debug", "response is = "+response+"\t"+response.getClass()); 
            Standort standort =  (Standort) response;
            locationMenuAdapter = new LocationMenuAdapter(StandorteFragment.this, standort);
            menuItemListLoc.setAdapter(locationMenuAdapter);
        }

        @Override
        public void onNoInternetError() {
            // TODO Auto-generated method stub
        }

        @Override
        public void onNoAccess() {
            // TODO Auto-generated method stub
        }
    }, true).invokeGetStandorte();
}

服务代理：

public class ServiceProxy {

    private static final boolean useFakeService = true;

    public static IWebServiceTask createWebServiceTask(Context ctx, RemoteCallListener listener, boolean hasInternet) {
        //if (useFakeService) {
        return new FakeService(ctx, listener);
    }
}

假服务：

public class FakeService extends CallWebServiceTask {

    private final boolean hasInternet = true;

    public FakeService(Context ctx, RemoteCallListener listener) {
        super(ctx, listener);
    }

    @Override
    protected WebEntityInterface doInBackground(CallWebServiceTask.InputParam... params) {
        System.currentTimeMillis();
        WebEntityInterface result = null;
        CallWebServiceTask.InputParam param = null;
        param = params[0];
        if (param.url.startsWith(Constants.invokeGetStandorte)) {
            return super.doInBackground(params);
        }
        try {
            if (hasInternet) {
                if (param.CALL_TYPE == InputParam.GET) {
                    result = sendGET(param);
                } else if (param.CALL_TYPE == InputParam.POST) {
                    result = sendPOST(param);
                }
            } else {
                LogService.log("CALL WEBSERVICE TASK", " NO INTERNET!!!!");
                result = new WebEntity(1, "No internet connection!");
            }
        } catch (UnknownHostException e) {
            LogService.err("WEB-SERVER-ERROR", e.getMessage(), e, LogService.LOG_LEVEL_FULL);
            result = new WebEntity(1, "No internet connection!");
        } catch (SocketException e) {
            LogService.err("WEB-SERVER-ERROR", e.getMessage(), e, LogService.LOG_LEVEL_FULL);
            result = new WebEntity(1, "No network connection!");
        } catch (Throwable e) {
            LogService.err("WEB-SERVER-ERROR", e.getMessage(), e, LogService.LOG_LEVEL_FULL);
            result = new WebEntity(2, "Network connection error!");
        }
        return result;
    }

    @Override
    public WebEntityInterface sendGET(CallWebServiceTask.InputParam param) throws Exception {
        if (param.url.startsWith(Constants.invokeGetStandorte)) {
            return super.sendGET(param);
        }
        SessionToken.Sessiontoken = "dfasmdfnasdfb";
        System.out.println("-----GET[" + param.clazz + "] : " + param.url);
        WebEntityInterface result = null;
        Populator populator = new Populator(new RandomDriver());
        result = populator.fill(param.clazz);
        result.setSuccess(true);
        System.out.println("------------RESULT :" + result);
        return result;
    }

    @Override
    public WebEntityInterface sendPOST(CallWebServiceTask.InputParam param) throws Exception {
        if (param.url.startsWith(Constants.invokeGetStandorte)) {
            return super.sendPOST(param);
        }
        SessionToken.Sessiontoken = "dfasmdfnasdfb";
        System.out.println("-----POST : " + param.url);
        WebEntityInterface result = null;
        Populator populator = new Populator(new RandomDriver());
        result = populator.fill(param.clazz);
        result.setSuccess(true);
        System.out.println("------------RESULT :" + result);
        return result;
    }

}

我的 LocationMenuAdapter：

public class LocationMenuAdapter extends BaseAdapter {
    private LayoutInflater mInflater;
    private AQuery aQuery;
    private Standort standort;
    private StandorteFragment standorteFragment;

    public LocationMenuAdapter(StandorteFragment standorteFragment, Standort standort) {
        this.standorteFragment  =standorteFragment;
        this.standort  =standort;
        this.aQuery = standorteFragment.aQuery;  
        mInflater = LayoutInflater.from(standorteFragment.getActivity());
    }

    public int getCount() {
        return standort.size();
    }

    public Object getItem(int position) {
        return position;
    }

    public long getItemId(int position) {
        return position;
    }

    public StandortItem getEKUrl(int i) {
        return standort.get(i);
    }

    public View getView(int position, View convertView, ViewGroup parent) { 
        ListContent holder;
        StandortItem standortItem = getEKUrl(position);
        if (convertView == null) {
            convertView = mInflater.inflate(R.layout.listviewinflate, null);
            holder = new ListContent();
            holder.text = (TextView) convertView.findViewById(R.id.TextView01);
            convertView.setTag(holder);
        } else {
            holder = (ListContent) convertView.getTag();
        }

        holder.text.setText(standortItem.Name);
        return convertView;
    }

    class ListContent {
        TextView text;

    }
}

最后但并非最不重要的：WebEntity：

public class Standort extends WebEntity {
    public static int IDtest;
    public ArrayList<StandortItem> standort = new ArrayList<StandortItem>();

    public void add(StandortItem standortItem) {
        standort.add(standortItem);
    }

    public int size() {
        return standort.size();
    }

    public StandortItem get(int i) {
        return standort.get(i);
    }

    public class StandortItem implements Serializable{
        public Integer ID;
        public String Name;
        public String Strasse;
        public String Email;
        public Integer PLZ;
        public String Ort;
        public String Telefon;
        public String Fax;
        public String Oeffnungszeiten;
        public Boolean Bar;
        public Boolean BusinessLunch;
        public Boolean Parkplatz;
        public Boolean Raucher;
        public String GooglemapsStrasse;

        public StandortItem(Integer ID, String Name,String Strasse, String Email,Integer PLZ, String Ort,String Telefon, String Fax,String Oeffnungszeiten, Boolean Bar,Boolean BusinessLunch, Boolean Parkplatz,Boolean Raucher,String GooglemapsStrasse) {
            super();
            this.ID = ID;
            this.Name = Name;
            this.Strasse = Strasse;
            this.Email = Email;
            this.PLZ = PLZ;
            this.Ort = Ort;
            this.Telefon = Telefon;
            this.Fax = Fax;
            this.Oeffnungszeiten = Oeffnungszeiten;
            this.Bar = Bar;
            this.BusinessLunch = BusinessLunch;
            this.Parkplatz = Parkplatz;
            this.Raucher = Raucher;
            this.GooglemapsStrasse = GooglemapsStrasse;
            IDtest=ID;
        }

        public String toString() {
            return "Standort [ID=" + ID + ", Name=" + Name + ", Strasse=" + Strasse + ", Email=" + Email + ", PLZ=" + PLZ + ", Ort=" + Ort + ", Telefon=" + Telefon + ", Fax=" + Fax + ", Oeffnungszeiten=" + Oeffnungszeiten + ", Bar=" + Bar + ", BusinessLunch=" + BusinessLunch + ", Parkplatz=" + Parkplatz + ", Raucher=" + Raucher + ",GooglemapsStrasse=" + GooglemapsStrasse + "]";
        }
    }
}

"Log.d("debug", "response is = "+response+"\t"+response.getClass())" 行说明如下：

 07-30 16:48:22.031: D/debug(25496): response is = [WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null], WebEntity [success=false, errorCode=0, errorMessage=null]]   class com.weinco.webservice.entity.Standorts

标准类：

public class Standorts extends WebListEntity<Standort> {
    public Standorts() {
        super();
    }

}

PS：我并没有真正使用Web服务，所以我是这方面的初学者，所以可能有部分代码写得不太正确，如果你也能提供帮助，我会非常感激。

所以我猜是这样的？我真的不知道你想在这里做什么......

    @Override
    public void onRemoteCallComplete(Object response) {
        Log.d("debug", "response is = "+response+"\t"+response.getClass()); 
        Standorts standorts =  (Standorts) response;

        //to get individual Standort objects from this WebListEntity<Standort> wrapper you need

        //get WebEntity from standorts

        //do whatever you need to do to make a Standort object out of that.

        Standort standort = new Standort();
        standort.restoreFromWebEntity(theWebEntityYouGotInStepOne);

        locationMenuAdapter = new LocationMenuAdapter(StandorteFragment.this, standort);
        menuItemListLoc.setAdapter(locationMenuAdapter);
        }
    }

但你得到的回应肯定是 Standorts。

看看这个 WebListEntity 类......它不是你发布的 WebEntity。换句话说，除了这个函数之外，你发布的所有这些代码都有点没用。

我设法通过使用 weblistentity 类 Standorts 作为适配器膨胀 webentities (Standort) 的列表来使其工作。
