如何转换JSONArray列出与GSON？ [英] How to convert JSONArray to List with Gson?

问题描述

在我的Andr​​oid项目我想收到的JSONArray转换到一个列表。随着这太回答我有一个远一点。我现在有以下的code：

In my Android project I'm trying to convert a received JSONArray to a List. With the help of this SO answer I got a bit further. I now have the following code:

Gson gson = new Gson();
JSONArray jsonArray = NetworkUtilities.getData("mymodeldata");
Type listType = new TypeToken<List<MyModel>>(){}.getType();
List<MyModel> myModelList = gson.fromJson(jsonArray, listType);

不幸的是，在最后一行，在GSON类型的方法fromJson（字符串型）不适用的参数（JSONArray，类型）投诉。我真的不知道该如何解决这个问题。

Unfortunately it complaints at the last line that the method fromJson(String, Type) in the type Gson is not applicable for the arguments (JSONArray, Type). I don't really know how to solve this.

有谁知道我可以解决这个问题？

Does anybody know how I can solve this?

推荐答案

如果您看到了答案，你可以看到，在 fromJson（）方法的第一个参数是字符串（JSON对象）。尝试使用的toString（）在JsonArray是这样的： -

If you see the answer there, you can notice that the first parameter in the fromJson() method was a String(the json object). Try to use the toString() on the JsonArray like this:-

List<MyModel> myModelList = gson.fromJson(jsonArray.toString(), listType);
