判断listview 各种滑动状态

  private boolean scrollFlag = false;// 标记是否滑动
  private int lastVisibleItemPosition;// 标记上次滑动位置

  listView.setOnScrollListener(new OnScrollListener() {
   @Override
   public void onScrollStateChanged(AbsListView view, int scrollState) {
    switch (scrollState) {
     case SCROLL_STATE_TOUCH_SCROLL:
      scrollFlag = true;
     break;
     case SCROLL_STATE_FLING:
      scrollFlag = false;
      break;
     case SCROLL_STATE_IDLE:
      scrollFlag = false;
      break;
     default:
      break;
    }
   }
   @Override
   public void onScroll(AbsListView view, int firstVisibleItem,
     int visibleItemCount, int totalItemCount) {
    if (scrollFlag) {
     if (firstVisibleItem > lastVisibleItemPosition) {//上滑
     }
     if (firstVisibleItem < lastVisibleItemPosition) {//下滑
     }
     if (firstVisibleItem == lastVisibleItemPosition) {
      return;
     }
     lastVisibleItemPosition = firstVisibleItem;
    }
   }
  });
