Question

我有这段代码：

    Carrera userRecived = null;
    HttpClient httpclient;
    HttpGet httpget;
    HttpResponse response;
    HttpEntity entity;
        /*Call Json service and Unserialize with Gson into the class*/
    try{
        httpclient = new DefaultHttpClient();

        httpget = new HttpGet(Url); 

        response = httpclient.execute(httpget);

        entity = response.getEntity();

            String result= EntityUtils.toString(entity);        

            Gson gson = new Gson();
            userRecived = gson.fromJson(result, Carrera.class);


    }catch(Exception error){throw new Error("Error en el get -- "+error.toString());}

我的问题是下一个错误： 03-08 19：07：42.899：E / AndroidRuntime（959）：java.lang.Error：Error en el getcom.google.gson.JsonParseException：期望数组但找到对象：com.jorgechu.circuitlacostera.Objetos.Carrera@405852d0

我等待来自php webservice的结果，结果可能是下一个JSON：

[{"Codigo":"1","Denominacion":"Popular de Xativa","Imagen":"1231313","Poblacion":"Xativa","Lugar":"Valencia","Fecha":"11 de Noviembre de 2012","Hora":"17:00","Descripcion":"para probar","Reglamento":"http:\/\/www.google.es","Kilometros":"21"}]

我有一个Carrera对象存储此信息。

我希望有人帮助我。谢谢。

Answer 1

你得到一个阵列，而不是一个物体。所以你必须做这样的事情：

Gson gson = new Gson();

Type collectionType = new TypeToken<Collection< Carrera >>(){}.getType();
List< Carrera > listOfObj= gson.fromJson(result, collectionType);

Answer 2

变化：

userRecived = gson.fromJson(result, Carrera.class);

为：

List<Carrera> userRecived = (List<Carrera>) gson.fromJson(result, new TypeToken<List<Carrera>>(){}.getType());

Web服务，JSON和Android。结果WS无法正常工作
