Question

我试图通过改造从服务器获取Android应用程序的回复。我设法发送请求没问题，但回调似乎总是为空，也似乎永远不会失败或成功，这听起来很奇怪。我不理解的其他一些事情是改造日志确实显示了响应，但回调变量似乎不能得到它们？！

我打算每隔几秒钟对服务器进行一次轮询以检查是否有变化，我不知道如何做到这一点，所以我尝试过一次又一次地发送请求但是没有运气，使用Observable似乎也无法工作，所以我只是采用异步回调（同步会很好，但android似乎不太喜欢它）。

以下是可能有用的代码的一些部分： get接口：

interface CamFindGet {
    @Headers("Authorization: CloudSight XXX")
    @GET("/image_responses/{token}")
    void getResult(@Path("token") String token,
                   Callback<resultClassGet> callback);}

其余适配器：

final RestAdapter restAdapter = new RestAdapter.Builder()
            .setEndpoint(API_URL)
            .setLogLevel(RestAdapter.LogLevel.FULL)
            .setLog(new RestAdapter.Log() {
                @Override
                public void log(String msg) {
                    String[] blacklist = {"Access-Control", "Cache-Control", "Connection", "Content-Type", "Keep-Alive", "Pragma", "Server", "Vary", "X-Powered-By"};
                    for (String bString : blacklist) {
                        if (msg.startsWith(bString)) {
                            return;
                        }
                    }
                    Log.d("Retrofit", msg);
                }
            }).build();

CamFindGet camFindGet = restAdapter.create(CamFindGet.class);

                try { //NOTE : result.getToken() is a valid token
                    getCamResult(camFindGet, result.getToken());
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }

实际的GET请求：

static void getCamResult(CamFindGet camFindGet, String token) throws InterruptedException {
    Log.d(TAG, "GET CAM RESULT");


        Log.d(TAG, "LOOP");
        camFindGet.getResult(token, new Callback<resultClassGet>() {
            @Override
            public void success(resultClassGet resultClass, Response response) {
                //Log.d(TAG, resultClass.getName());

                if (resultClass.getStatus().equals("completed") || resultClass.getStatus().equals("not found"))
                    completedGet = 1;

                if(completedGet==1) {
                    resultString = new String(resultClass.getName());
                    Log.d(TAG, "RESULT : "+resultString);
                }
                Log.d(TAG, resultClass.getStatus());
            }

            @Override
            public void failure(RetrofitError retrofitError) {
                Log.d(TAG, retrofitError.getMessage());
                Log.d(TAG, "FAILURE?");
            }
        });

}

注意：为了成功，一些LOG应出现在调试中（FAILURE？或get.status()，但两者都没有）

编辑：我可能会做一些事情，显然对于异步请求，您需要在其余的适配器创建中使用.setExecutors()，我试图了解当前如何工作。

Answer 1

解决问题，只需要以这种方式创建执行程序：

Executor executor = Executors.newCachedThreadPool();

然后在制作其余适配器时，添加setExecutors行：

 RestAdapter.Builder builder = new RestAdapter.Builder();
    builder.setEndpoint(API_URL);
    builder.setLogLevel(RestAdapter.LogLevel.FULL);
    builder.setExecutors(executor, null); //<<-- this line
    builder.setLog(new RestAdapter.Log() {
        @Override
        public void log(String msg) {
            String[] blacklist = {"Access-Control", "Cache-Control", "Connection", "Content-Type", "Keep-Alive", "Pragma", "Server", "Vary", "X-Powered-By"};
            for (String bString : blacklist) {
                if (msg.startsWith(bString)) {
                    return;
                }
            }
            Log.d("Retrofit", msg);
        }
    });

麻烦使用改造
