示范：
` int lastPositon = mAdapter.getCount() - 1;
if (data.getTimeStamp() == mAdapter.getItem(lastPositon).getTimeStamp()) { //如果推送的时间戳和最后一根分时点时间戳一致，就刷新它。

lastMinuteData.openPrice = data.openPrice;
lastMinuteData.highPrice = data.highPrice;
lastMinuteData.lowPrice = data.lowPrice;
lastMinuteData.closePrice = data.closePrice;
lastMinuteData.volume = data.volume;
lastMinuteData.timeStamp = data.timeStamp;
KlineDataHelper.calculate(mAdapter.getDataList());

                mAdapter.notifyDataSetChanged();
            } else {         //否则，就增加一个分时点
