无法在Android中正确设置retrofit header

public class HeaderInterceptor implements Interceptor {
    @Override
    public Response intercept(Chain chain) throws IOException {
        Request originalRequest = chain.request();
        Request.Builder builder = originalRequest.newBuilder()
                .header("HeaderName", "HeaderValue");
        Request newRequest = builder.build();
        return chain.proceed(newRequest);
    }
}

OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
httpClient.addInterceptor(new HeaderInterceptor());

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("https://api.example.com/")
        .client(httpClient.build())
        .addConverterFactory(GsonConverterFactory.create())
        .build();

public interface ApiService {
    @GET("endpoint")
    Call<ResponseBody> getData();
}

ApiService apiService = retrofit.create(ApiService.class);
Call<ResponseBody> call = apiService.getData();
call.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
        // 处理响应
    }

    @Override
    public void onFailure(Call<ResponseBody> call, Throwable t) {
        // 处理失败
    }
});
