android - Web 服务、JSON 和 Android。结果 WS 不能正常工作

Question

我有这个代码:

    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

我在等待来自 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"}]

我有一个对象 Carrera，用于存储这些信息。

我希望有人能帮助我。谢谢。

Answer 1

你得到的是一个数组，而不是一个对象。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);
