代码很简单，给mListView监听onScrollListener事件，然后在onScroll进行判断
//listView中第一项的索引
private int mListViewFirstItem = 0;
//listView中第一项的在屏幕中的位置
private int mScreenY = 0;
//是否向上滚动
private boolean mIsScrollToUp = false;
@Override
public void onScroll(AbsListView absListView, int firstVisibleItem,int visibleItemCount, int totalItemCount) {
if(mListView.getChildCount()>0)
{
boolean isScrollToUp = false;
View childAt = mListView.getChildAt(firstVisibleItem);
int[] location = new int[2];
childAt.getLocationOnScreen(location);
Log.d("onScroll", "firstVisibleItem= "+firstVisibleItem+" , y="+location[1]);
if(firstVisibleItem!=mListViewFirstItem)
{
if(firstVisibleItem>mListViewFirstItem)
{
Log.e("--->", "向上滑动");
isScrollToUp = true;
}else{
Log.e("--->", "向下滑动");
isScrollToUp = false;
}
mListViewFirstItem = firstVisibleItem;
mScreenY = location[1];
}else{
if(mScreenY>location[1])
{
Log.i("--->", "->向上滑动");
isScrollToUp = true;
}
else if(mScreenY<location[1])
{
Log.i("--->", "->向下滑动");
isScrollToUp = false;
}
mScreenY = location[1];
}
if(mIsScrollToUp!=isScrollToUp)
{
onScrollDirectionChanged(mIsScrollToUp);
}
}
}
private void onScrollDirectionChanged(boolean isScrollToUp)
{
}
