如何使用Retrofit从JsonArray获取单个对象？

Question

我正在尝试使用Retrofit从我的API获取数组。然后，我需要从数组中获取某些对象，以便在我的应用程序的不同部分中使用。使用下面的代码，我可以获得成功的响应，但是当我尝试记录响应时，我得到了这个......

myapp.com.myapp.LocationsModel@9a0d130

我需要返回实际数组，以便从数组中获取对象（字符串）。我曾尝试过谷歌和Stack Overflow的几种不同的实现方式，但是我不能让它在我的生活中发挥作用。也许我忽略了一些简单的事情。这是我第一次使用Retrofit而不是Volley。谢谢你的帮助。这是我的LocationsModel模型。我还粘贴了我正在尝试接收和解析的api响应。

模型

@GET("locations")
    Call<List<LocationsModel>> getLocations(@Header("authorization") String token);

客户端

public void getContests() {
       // SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
        String token = LoginActivity.authToken;
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(Interface.BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .build();

        Interface api = retrofit.create(Interface.class);
            Log.v("sendtoken", token);

        Call<List<LocationsModel>> call = api.getLocations(token);



        call.enqueue(new Callback<List<LocationsModel>>() {
            @Override
            public void onResponse(Call<List<LocationsModel>> call, Response<List<LocationsModel>> response) {
                int statusCode = response.code();
                Log.d("Response Code", "Response Code: " + statusCode);
                Log.d("LocArray", "arr: " + Arrays.toString(response.body().toArray()));

            }

            @Override
            public void onFailure(Call<List<LocationsModel>> call, Throwable t) {
                Log.e("response-failure", call.toString());
                t.printStackTrace();
            }
        });
    }
