I searched here on stackoverflow but I still could not find the solution, so my question.
I created this method to deserialize the json that is coming (must be generic, since all calls pass here):
public class GsonUtil {
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();
..............
//ARRAY
builder.registerTypeAdapter(List.class, new JsonArrayListDeserializer());
//HOW TO DO
//builder.registerTypeAdapter(List.class, new JsonArrayListSerializer());
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);
}
}
}
}
After creating this method, the data started arriving in the adapter, but the error appears when trying to insert them in the view.
Here is the error:
java.lang.ClassCastException: com.google.gson.internal.LinkedTreeMap cannot be cast to br.com.sisteplan.evida.atendimento.service_atendimento.vo.AgendamentoVo

ViewHolder vh = new ViewHolder(v);
return vh;
}
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
AgendamentoVo pacienteVo = getUsuarioVo(position);
// Configura a view com o Id do Agendamento

}
LogCat takes me to this error line:
holder.mTextViewNome.setText(pacienteVo.getPaciente().getNmUsuario() != null ? pacienteVo.getPaciente().getNmUsuario() : "Branco");
What do I have to do to resolve this error? Thank you!
EDIT:
Result in my adapter:
