How to convert JSONArray to List with Gson?
提问by kramer65
In my Android project I'm trying to convert a received JSONArray to a List. With the help of this SO answerI got a bit further. I now have the following code:
在我的 Android 项目中，我试图将接收到的 JSONArray 转换为列表。在这个 SO 答案的帮助下，我更进一步。我现在有以下代码：
Gson gson = new Gson();
JSONArray jsonArray = NetworkUtilities.getData("mymodeldata");
Type listType = new TypeToken<List<MyModel>>(){}.getType();
List<MyModel> myModelList = gson.fromJson(jsonArray, listType);
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.
不幸的是，它在最后一行抱怨 Gson 类型中的 fromJson(String, Type) 方法不适用于参数 (JSONArray, Type)。我真的不知道如何解决这个问题。
Does anybody know how I can solve this?
有谁知道我该如何解决这个问题？

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:-
如果您在那里看到答案，您会注意到该fromJson()方法中的第一个参数是 a String（json 对象）。尝试toString()像这样在 JsonArray 上使用：-
List<MyModel> myModelList = gson.fromJson(jsonArray.toString(), listType);
