Question

我试图制作我认为对谷歌应用引擎项目的简单调用。从单元测试中，如果我直接访问api，则调用正常。但是我不能这样做，因为调用是阻塞的，所以它必须从异步任务运行。

似乎发生的事情是：继承自ActivityInstrumentationTestCase2的单元测试会设置活动并填充一些值

然后我点击按钮发出请求：

   final Button mBet = (Button) mActivity.findViewById(R.id.mybutton);
   mActivity.runOnUiThread(new Runnable() {
            @Override
            public void run() {
                mName.setText("blah");
                mBet.performClick();
            }
        });

然后调用底层代码启动异步任务：

public void bet() throws IOException, InterruptedException {

    mMakeTask = new AsyncTask<Void, Void, Model>() {
        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            mBetWait = new ProgressDialog(getActivity());
            mBetWait.setCancelable(true);
            mBetWait.show();
        }

        @Override
        protected Model doInBackground(Void... voids) {
            try {
                mModel = mController.makeBet(mModel.getBetName(), mModel.getDescription(), mModel.getAnswer(), mModel.getAgainst());
            } catch (IOException e) {
                e.printStackTrace();
            }

            return mModel;
        }

        @Override
        protected void onPostExecute(BetModel model) {
            super.onPostExecute(model);
            Context context = getActivity();
            Intent intent = new Intent(context, OtherActivity.class);
            intent.putExtra("bet", mModel);
            mBetWait.dismiss();

            context.startActivity(intent);
        }
    };


    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
        mMakeTask.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);
    } else {
        mMakeTask.execute();
    }
}

我忘了添加...当调用控制器时，它归结为一个appengine调用：

public BetInfo makeBet(BetRequest info) throws IOException {
    Betrequestendpoint.Builder endpointBuilder = new Betrequestendpoint.Builder(
            AndroidHttp.newCompatibleTransport(),
            new JacksonFactory(),
            new HttpRequestInitializer() {
                public void initialize(HttpRequest httpRequest) { }
            });
    Betrequestendpoint endpoint = CloudEndpointUtils.updateBuilder(
            endpointBuilder).build();

    BetRequest result = endpoint.insertBetRequest(info).execute();
    BetInfo resultInfo = new BetInfo();
    resultInfo.setName(result.getName());
    resultInfo.setDescription(result.getDescription());
    resultInfo.setId(result.getId());

    return resultInfo;
}

为了使这更奇怪......请求调用似乎被阻止从具有堆栈跟踪的客户端：

似乎发生了什么，是我运行测试，它会进入弹出进度对话框的位置。如果我然后手动与模拟器中的应用程序交互（并回击或某事），则进度对话框消失并且调用完成 - 然后测试通过。

如果我只是不管它，似乎进度对话框很乐意永远旋转。

非常感谢任何帮助。
