public void setOnScrollListener(OnScrollListener listener) {
mScrollListener = listener;
}
public void addOnScrollListener(OnScrollListener listener) {
if (mScrollListeners == null) {
mScrollListeners = new ArrayList<>(http://www.my516.com);

mScrollListeners.add(listener);

使用setOnScrollListener()方法時，注解會提示此方法即將被廢棄的方法：
Inspection info: Reports where deprecated code is used in the specified inspection scope.
所以，我們采用addOnScrollListener()方法將我們自定義的OnScrollListener類添加進去。
