的ListView：限制滚动速度

Question

可能重复：
Android Listview slow down scroll speed

当用户刷上ListView其滚动速度可以得到相当高。我想限制速度 - 有可能吗？

Answer 1

检查了这一点 - ：

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) { 
     } 
    }
