考虑到有问题的错误，我添加了行
builder.registerTypeAdapter(ArrayList.class, new JsonDoubleDeserializer());
builder.registerTypeAdapter(ArrayList.class, new JsonDoubleSerializer());
采用以下createJsonObject方法：
public static Gson createGsonObject() {
// Formado de data alterado, outro formato não estava convertendo
// Alterado para setar // na saída devido problema com WebService
GsonBuilder builder = new GsonBuilder();
builder.setDateFormat(GsonUtil.FORMAT_DATE).create();
builder.registerTypeAdapter(Boolean.class,
new JsonBooleanDeserializer());
// Tratamento de BigDecimal
builder.registerTypeAdapter(BigDecimal.class,
new JsonBigDecimalDeserializer());
// Tratamento de Byte[]
builder.registerTypeAdapter(byte[].class,
new JsonByteArrayDeserializer());
//Tratamento de deserialização de Date java formato GMT timezone
builder.registerTypeAdapter(Date.class, new JsonDateDeserializer());
builder.registerTypeAdapter(Date.class, new JsonDateSerializer());
//TRATAMENTO DE DOUBLE
builder.registerTypeAdapter(Double.class, new JsonDoubleDeserializer());
builder.registerTypeAdapter(Double.class, new JsonDoubleSerializer());
//ADD TO ARRAY
builder.registerTypeAdapter(ArrayList.class, new JsonDoubleDeserializer());
builder.registerTypeAdapter(ArrayList.class, new JsonDoubleSerializer());
Gson gson = builder.create();
return gson;
}
添加这些行时碰巧会出现转换错误，因为我返回一个double但是我问一个arraylist。如果我是正确的，我如何将json转换为返回arraylist？
以下是方法：
/**
* Deserialização de ARRAY??????? Java
*/
private static class JsonDoubleSerializer implements JsonSerializer<Double> {
@Override
public JsonElement serialize(Double aDouble, java.lang.reflect.Type type, JsonSerializationContext jsonSerializationContext) {
if (aDouble == aDouble.longValue())
return new JsonPrimitive(aDouble.longValue());
return new JsonPrimitive(aDouble);
}
}
// ARRAYLIST ?????????????????????????????
private static class JsonDoubleDeserializer implements
JsonDeserializer<Double> {
/*
* (non-Javadoc)
*
* @see
* com.google.gson.JsonDeserializer#deserialize(com.google.gson.JsonElement
* , java.lang.reflect.Type, com.google.gson.JsonDeserializationContext)
*/
@Override
public Double deserialize(JsonElement arg0,
java.lang.reflect.Type arg1, JsonDeserializationContext arg2)
throws JsonParseException {
String value = arg0.getAsJsonPrimitive().getAsString();
return new Double(value);
}
}
这是我的片段：
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
......
ProfissionalVo profissionalVo = new ProfissionalVo();
profissionalVo.setCdProfissional(4);
new AsyncTaskListaAtendimentos(FragmentFilaAtendimento.this.getFragmentManager(), false).execute(profissionalVo);
}
private class AsyncTaskListaAtendimentos extends BaseAsyncTask<ProfissionalVo,Void,AsyncTaskResult<RetornoAgendamentoVo>>{
private FragmentManager mFragmentManager;
private ProfissionalVo profissionalVo;
public AsyncTaskListaAtendimentos(FragmentManager fragmentManager, boolean isDialogShow) {
super(fragmentManager, isDialogShow);
this.mFragmentManager = fragmentManager;
}
@Override
protected AsyncTaskResult doInBackground(ProfissionalVo... profissionalVos) {
try {
profissionalVo = profissionalVos[0];
RetornoAgendamentoVo retorno = ServiceAgendamentoVo.getInstance(MyApplicationInstance.getInstanceApplicationSingleton().getDsChaveAcessoWbs())
.consultaAgendamentos1(profissionalVo);
return new AsyncTaskResult<RetornoAgendamentoVo>(retorno);
}catch (Exception e){
return new AsyncTaskResult<Retorno>(e);
}
}
@Override
protected void onPostExecute(AsyncTaskResult<Retorno> respProfissionalVO) {
super.onPostExecute(respProfissionalVO);
if (respProfissionalVO.getExceptionResult() == null && getActivity() != null){
retornoAgendamentoVo = (RetornoAgendamentoVo) respProfissionalVO.getResult();
agendamentoVos = new ArrayList<>();
agendamentoVos = retornoAgendamentoVo.getRetorno();
// specify an adapter (see also next example)
mAdapter = new CustomRecyclerViewAdapterFila(agendamentoVos,
(AppCompatActivity) getActivity(), this);
}
}
}

答案 0 :(得分：0)
我认为问题确实存在：您编写的代码是什么版本的Java API，以及它实际运行的Java版本是什么？不完全确定，但是我认为整个java.lang.invoke包在Java 7之前都没有引入，所以你可能正在编译Java 7或8，但是在Java 6或更早版本上运行。
答案 1 :(得分：0)
我通过创建以下方法解决了这个问题：
解串器：
public static Gson createGsonObject() {
// Formado de data alterado, outro formato não estava convertendo
// Alterado para setar // na saída devido problema com WebService
GsonBuilder builder = new GsonBuilder();
....
//Array
builder.registerTypeAdapter(List.class, new JsonArrayListDeserializer());
Gson gson = builder.create();
return gson;
}
private static class JsonArrayListDeserializer<T> implements JsonDeserializer<ArrayList<T>>{
@Override
public ArrayList<T> deserialize(JsonElement jsonElement, java.lang.reflect.Type type, JsonDeserializationContext jsonDeserializationContext) throws JsonParseException {
try {
Gson gson = new Gson();
TypeToken<ArrayList<T>> token = new TypeToken<ArrayList<T>>() {};
ArrayList<T> value = gson.fromJson(jsonElement, token.getType());
return value;
} catch (ClassCastException e) {
throw new JsonParseException("Cannot parse json Boolean '"
+ jsonElement.toString() + "'", e);
}
}
}
所以在我看来问题是让json解析。使用这种添加的方法，错误不再出现，数据已经到了应该去的地方。
