Android-Volley RequestFuture超时

Question

我在使用Volley的RequestFuture类时遇到了一个问题。实际上，它只是停在wait(0)；在下面RequestFuture类中的doget()函数中，并不会像我认为的那样被onResponse或onErrorResponse唤醒。

private synchronized T doGet(Long timeoutMs)
        throws InterruptedException, ExecutionException, TimeoutException {
    if (mException != null) {
        throw new ExecutionException(mException);
    }

    if (mResultReceived) {
        return mResult;
    }

    if (timeoutMs == null) {
        wait(0);
    } else if (timeoutMs > 0) {
        wait(timeoutMs);
    }

    if (mException != null) {
        throw new ExecutionException(mException);
    }

    if (!mResultReceived) {
        throw new TimeoutException();
    }

    return mResult;
}

@Override
public boolean isCancelled() {
    if (mRequest == null) {
        return false;
    }
    return mRequest.isCanceled();
}

@Override
public synchronized boolean isDone() {
    return mResultReceived || mException != null || isCancelled();
}

@Override
public synchronized void onResponse(T response) {
    mResultReceived = true;
    mResult = response;
    notifyAll();
}

@Override
public synchronized void onErrorResponse(VolleyError error) {
    mException = error;
    notifyAll();
}

这就是我试图把上面这一切称为的方式。

    RequestFuture<JSONObject> future = RequestFuture.newFuture();
    JsonObjectRequest myReq = new JsonObjectRequest(Request.Method.POST, url, jsonObj, future, future);
    requestQueue.add(myReq);

    try {

        JSONObject response = future.get();
    } catch (InterruptedException e) {
        // handle the error
    } catch (ExecutionException e) {
        // handle the error
    }

requestqueue.add（myReq）；

与

future.setrequest（requestqueue.add（myReq））；

向get方法添加一个超时将提供捕捉错误的能力，如果没有超时，则它将错误发送回主线程。因此，用JSONObject response=future.get（）；更改JSONObject response=future.get(REQUEST_TIMEOUT,timeunit.seconds）；应该可以做到这一点，并将其包装在超时的try catch中
