排球 - 在超时标记处进行重复的POST呼叫

Question

我遇到的问题是，当Volley达到超时标记时会发出重复的POST请求。我通过DefaultRetryPolicy设置超时，同时还将重试次数设置为0.我尝试了一些其他组合而没有改变行为。

volleyRequest.setRetryPolicy(new DefaultRetryPolicy(timeout*1000, 0, 1f));

我也尝试过扩展DefaultRetryPolicy类以确保

retry(VolleyError error)

抛出错误而不尝试在任何时候重试。

class customRetryPolicy extends DefaultRetryPolicy{
    private int mCurrentTimeoutMs;

    /** The current retry count. */
    private int mCurrentRetryCount;

    /** The maximum number of attempts. */
    private final int mMaxNumRetries;

    /** The backoff multiplier for the policy. */
    private final float mBackoffMultiplier;

    /** The default socket timeout in milliseconds */
    public static final int DEFAULT_TIMEOUT_MS = 10000;

    /** The default number of retries */
    public static final int DEFAULT_MAX_RETRIES = 0;

    /** The default backoff multiplier */
    public static final float DEFAULT_BACKOFF_MULT = 1f;

    /**
     * Constructs a new retry policy using the default timeouts.
     */
    public customRetryPolicy() {
        this(DEFAULT_TIMEOUT_MS, DEFAULT_MAX_RETRIES, DEFAULT_BACKOFF_MULT);
    }

    /**
     * Constructs a new retry policy.
     * @param initialTimeoutMs The initial timeout for the policy.
     * @param maxNumRetries The maximum number of retries.
     * @param backoffMultiplier Backoff multiplier for the policy.
     */
    public customRetryPolicy(int initialTimeoutMs, int maxNumRetries, float backoffMultiplier) {
        mCurrentTimeoutMs = initialTimeoutMs;
        mMaxNumRetries = maxNumRetries;
        mBackoffMultiplier = backoffMultiplier;
    }

    /**
     * Returns the current timeout.
     */
    @Override
    public int getCurrentTimeout() {
        return mCurrentTimeoutMs;
    }

    /**
     * Returns the current retry count.
     */
    @Override
    public int getCurrentRetryCount() {
        return mCurrentRetryCount;
    }

    /**
     * Returns the backoff multiplier for the policy.
     */
    public float getBackoffMultiplier() {
        return mBackoffMultiplier;
    }

    /**
     * Prepares for the next retry by applying a backoff to the timeout.
     * @param error The error code of the last attempt.
     */
    @Override
    public void retry(VolleyError error) throws VolleyError {
        throw error;
    }

    /**
     * Returns true if this policy has attempts remaining, false otherwise.
     */
    protected boolean hasAttemptRemaining() {
        return false;
    }
}

但是，添加日志后，我无法看到此方法在超时标记命中时被触发。它会触发其他错误，然后适当地抛出错误。

还有其他人遇到过此问题吗？
