Android：刷新后，ArrayAdapter越界在getView上崩溃

我目前在向下滚动列表视图并快速按下刷新时遇到崩溃问题。Eclipse给了我

11-25 23:58:51.511: E/AndroidRuntime(29736): java.lang.IndexOutOfBoundsException: Invalid index 1, size is 1

在此代码上：

            mAdapter = new ArrayAdapter<Link>(getActivity(), R.layout.link_item,
            mLinkManager.getLinks()) {
        @Override
        public int getCount() {
            return mLinkManager.getLinks().size();
        }

        public long getItemId(int position) {
            return mLinkManager.getLinks().get(position).getId().hashCode();
        }

        public Link getItem(int position) {
            return mLinkManager.getLinks().get(position);
        }

        public View getView(int position, View convertView, ViewGroup parent) {
            if (convertView == null) {
                convertView = getActivity().getLayoutInflater().inflate(
                        R.layout.link_item, null);
            }

            Link link = mLinkManager.getLinks().get(position);

            // Set textview stuff from links here

            return convertView;
        };
    };

    setListAdapter(mAdapter);
}

崩溃发生在最后一行。一旦按下刷新，有没有办法停止getView（）方法？任何帮助将不胜感激。

private class RefreshLinksTask extends AsyncTask<Void, Void, Void> {
    @Override
    protected void onPreExecute() {
        Log.d(TAG, "Refreshing...");
        if (mIsRefreshing || mIsDownloading)
            cancel(true);
        mIsRefreshing = true;
        super.onPreExecute();
    }

    @Override
    protected Void doInBackground(Void... params) {
        mLinkManager.refreshLinks();
        return null;
    }

    @Override
    protected void onPostExecute(Void result) {
        if (mAdapter != null) {
            mAdapter.notifyDataSetChanged();
        } 
        else {
            createAdapter();
        }
        mIsRefreshing = false;
        super.onPostExecute(result);
    }
}
