我使用库在此处输入链接描述

我的课程和方法：

public static class Test {
        public String name;
        public String soname;
        public String age;
        public String country;
    }
    private void setData(){
        Ion.with(getActivity())
                .load("http://............")
                .as(new TypeToken<List<Test>>(){})
                .setCallback(new FutureCallback<List<Test>>() {
                    @Override
                    public void onCompleted(Exception e, List<Test> result) {
                        // do stuff with the result or error
                        Log.d("ionmy", e.toString());
Toast.makeText(getActivity(), result.get(0).name, Toast.LENGTH_LONG).show();
                    }
                });

    }

这样我得到数据：

[{"name":"Vasya","soname":"Pupkin","age":"25","country":"Russian Federation"},{"name":"Iliya","soname":"Strelnikov","age":"43","country":"Kazahstan"},{"name":"Iliya","soname":"Lagutenko","age":"49","country":"Ukraine"}]

我的错误：

D/ionmy﹕ com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2

异常表示返回的是 JsonObject，而不是 JsonArray（列表）。
