// 设置ListView到记录的位置  
mListView.setSelection(mPosition);  
mListView.setOnScrollListener(new OnScrollListener() {  
    // 滚动状态改变时调用 
    @Override  
    public void onScrollStateChanged(AbsListView view, int scrollState) {  
        // 不滚动时保存当前滚动到的位置  
        if (scrollState == OnScrollListener.SCROLL_STATE_IDLE) {  
            mPosition = mListView.getFirstVisiblePosition();  
        }  
    }  
 // 滚动时调用 
    @Override  
    public void onScroll(AbsListView view, int firstVisibleItem,  
            int visibleItemCount, int totalItemCount) {  
    }  
});

//给ListView设置监听器
backgroundList.setOnScrollListener(scrollListener);
private OnScrollListener scrollListener = new OnScrollListener() {
 
                @Override
                public void onScroll(AbsListView arg0, int arg1, int arg2, int arg3) {
                }
 
                @Override
                public void onScrollStateChanged(AbsListView view, int scrollState) {
                        if (scrollState == OnScrollListener.SCROLL_STATE_IDLE) {
                                // scrollPos记录当前可见的List顶端的一行的位置 
                               scrollPos = myList.getFirstVisiblePosition(); 
                        }
                        if (arrayList != null) {  
              View v=myList .getChildAt(0);
              scrollTop=(v==null)?0:v.getTop();
            }  
         }
        };

调用setAdapter之后恢复位置：
myList .setSelectionFromTop(scrollPos, scrollTop);
