ListView：限制滚动速度

Question

  

可能重复：
  Android Listview slow down scroll speed

当用户在ListView上滑动时，其滚动速度可能会非常高。我想限制速度 - 有可能吗？

检查出来 - ：

private class SpeedMeterOnScrollListener implements OnScrollListener {

        private long timeStamp;
        private int lastFirstVisibleItem;

        public SpeedMeterOnScrollListener() {
            timeStamp = System.currentTimeMillis();
            lastFirstVisibleItem = 0;
        }

        @Override
        public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
            long lastTime = System.currentTimeMillis();
            //calculate speed by firstVisibleItem, lastFirstVisibleItem, timeStamp and lastTime
            timeStamp = lastTime;
            lastFirstVisibleItem = firstVisibleItem;
        }

        @Override
        public void onScrollStateChanged(AbsListView view, int scrollState) {
        }
    }
