从Gson字符串创建对象不起作用

在FModel中发现问题，确实存在Uri。

通过编写解决此问题：

public class UriSerializer implements JsonSerializer<Uri> {    public JsonElement serialize(Uri src, Type typeOfSrc, JsonSerializationContext context) {        return new JsonPrimitive(src.toString());    }}public class UriDeserializer implements JsonDeserializer<Uri> {    @Override    public Uri deserialize(final JsonElement src, final Type srcType,     final JsonDeserializationContext context) throws JsonParseException {        return Uri.parse(src.getAsString());    }}

并像这样进行Gson转换：

Gson gson = new GsonBuilder()     .registerTypeAdapter(Uri.class, new UriSerializer())     .create();        bdl.putString("oModel",gson.toJson(oModel));

并在oncreate中重建它：

Gson gson = new GsonBuilder()         .registerTypeAdapter(Uri.class, new UriDeserializer())         .create(); jsonMyObject = args.getString("oModel"); mOrderModel = gson.fromJson(jsonMyObject, FModel.class);
