@Deprecated
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);
}
public void removeOnScrollListener(OnScrollListener listener) {
if (mScrollListeners != null) {
mScrollListeners.remove(listener);
}
}
使用setOnScrollListener()方法时，注解会提示此方法即将被废弃的方法：
Inspection info: Reports where deprecated code is used in the specified inspection scope.

所以，我们采用addOnScrollListener()方法将我们自定义的OnScrollListener类添加进去。
