下拉刷新动画不能关闭的BUG

最近项目中遇到一个下拉刷新动画不能关闭的bug，在连续点击强制手动刷新的时候，刷新动画一直存在不能关闭；下拉刷新则没有此问题。查阅代码发现是刷新控件的问题：

    //比较新旧滚动值    if(oldScrollValue !=newScrollValue) {       //滚动        if (delayMillis > 0) {            postDelayed(mCurrentSmoothScrollRunnable, delayMillis);        } else {            post(mCurrentSmoothScrollRunnable);        }    }

mCurrentSmoothScrollRunnable代码

final class SmoothScrollRunnable implements Runnable {        private final Interpolator mInterpolator;        private final int mScrollToY;        private final int mScrollFromY;        private final long mDuration;        private OnSmoothScrollFinishedListener mListener;        private boolean mContinueRunning = true;        private long mStartTime = -1;        private int mCurrentY = -1;        public SmoothScrollRunnable(int fromY, int toY, long duration, OnSmoothScrollFinishedListener listener) {            mScrollFromY = fromY;            mScrollToY = toY;            mInterpolator = mScrollAnimationInterpolator;            mDuration = duration;            mListener = listener;        }        @Override        public void run() {            if (mStartTime == -1) {                mStartTime = System.currentTimeMillis();            } else {                ......                mCurrentY = mScrollFromY - deltaY;                setHeaderScroll(mCurrentY);            }            // If we're not at the target Y, keep going...            if (mContinueRunning && mScrollToY != mCurrentY) {                ViewCompat.postOnAnimation(PullToRefreshBase.this, this);            }              //mScrollToY == mCurrentY滚动到指定位置，下拉界面完全展开，调用滚动结束监听            else {                if (null != mListener) {                    mListener.onSmoothScrollFinished();                }            }        }

原因：实现机制滚动到指定位置，下拉界面完全展开，调用滚动结束监听。如果正好下拉界面完全展开的时候点击了强制刷新，则不会调用滚动结束监听

解决方案：

    if(oldScrollValue !=newScrollValue) {       //滚动        if (delayMillis > 0) {            postDelayed(mCurrentSmoothScrollRunnable, delayMillis);        } else {            post(mCurrentSmoothScrollRunnable);        }    }    //增加以下代码解决手动刷新问题    else{        if (null != listener) {            listener.onSmoothScrollFinished();        }    }
