如何在改造2.0 Android中发送标题

Question

这是我目前使用Retrofit 2.0进行API CALL的代码并且工作正常

private void getWallet(String api_key) {
    final ProgressDialog loading = new ProgressDialog(ActivityWallet.this, R.style.MyTheme);
    loading.setCancelable(true);
    loading.show();


    Retrofit retrofit = new Retrofit.Builder()
            .addConverterFactory(GsonConverterFactory.create())
            .baseUrl(Constants.BASERESTURL)
            .client(httpClient)
            .build();

    EndPoints apiOrders = retrofit.create(EndPoints.class);
    Call<ArrayList<Order>> call = apiOrders.getWallet(api_key);
    call.enqueue(new Callback<ArrayList<Order>>() {
        @Override
        public void onResponse(Response<ArrayList<Order>> response, Retrofit retrofit) {
            loading.dismiss();
            ArrayList<Order> orders = response.body();
            Utility.setOrders(orders);
            AdapterOrder adapter = new AdapterOrder(getApplicationContext(), Utility.getOrders());
            orderListView.setAdapter(adapter);
        }

        @Override
        public void onFailure(Throwable t) {
            Utility.displaySnackBar(coordinatorLayout, "INTERNET CONNECTION LOST");
            loading.dismiss();
        }
    });
}

现在我需要在请求中添加标头。谷歌搜索后我才知道我可以使用okhttp。我创建了如下新代码，在请求中添加标头：

private void getWallet(String api_key) {
    final ProgressDialog loading = new ProgressDialog(ActivityWallet.this, R.style.MyTheme);
    loading.setCancelable(true);
    loading.show();




    OkHttpClient httpClient = new OkHttpClient();
    httpClient.networkInterceptors().add(new Interceptor() {
        @Override
        public Response intercept(Chain chain) throws IOException {
            Request request = chain.request().newBuilder().addHeader("test", "test").build();
            return chain.proceed(request);
        }
    });

    Retrofit retrofit = new Retrofit.Builder()
            .addConverterFactory(GsonConverterFactory.create())
            .baseUrl(Constants.BASERESTURL)
            .client(httpClient)
            .build();

    EndPoints apiOrders = retrofit.create(EndPoints.class);
    Call<ArrayList<Order>> call = apiOrders.getWallet(api_key);
    call.enqueue(new Callback<ArrayList<Order>>() {
        @Override
        public void onResponse(Response<ArrayList<Order>> response, Retrofit retrofit) {
            loading.dismiss();
            ArrayList<Order> orders = response.body();
            Utility.setOrders(orders);
            AdapterOrder adapter = new AdapterOrder(getApplicationContext(), Utility.getOrders());
            orderListView.setAdapter(adapter);
        }

        @Override
        public void onFailure(Throwable t) {
            Utility.displaySnackBar(coordinatorLayout, "INTERNET CONNECTION LOST");
            loading.dismiss();
        }
    });
}

但它在此行返回chain.proceed（request）;

中给出了编译错误

required: retrofit.Response
found: com.squareup.okhhtp.Response

将导入更改为com.squareup.okhhtp.Response后，在改进响应中看到很多错误。

任何人都可以帮助我，我做错了吗？如何解决？
