也可以看看：

Public constructors
`RecyclerView.OnScrollListener()`

Public methods
`void`	`onScrollStateChanged(RecyclerView recyclerView, int newState)` 回调方法在RecyclerView的滚动状态改变时被调用。
`void`	`onScrolled(RecyclerView recyclerView, int dx, int dy)` 回滚方法在RecyclerView被滚动时被调用。

From class java.lang.Object

RecyclerView.OnScrollListener ()

void onScrollStateChanged (RecyclerView recyclerView, 
                int newState)

回调方法在RecyclerView的滚动状态改变时被调用。

Parameters
`recyclerView`	`RecyclerView`: The RecyclerView whose scroll state has changed.
`newState`	`int`: The updated scroll state. One of `SCROLL_STATE_IDLE`, `SCROLL_STATE_DRAGGING` or `SCROLL_STATE_SETTLING`.

void onScrolled (RecyclerView recyclerView, 
                int dx, 
                int dy)

回滚方法在RecyclerView被滚动时被调用。这将在滚动完成后调用。

如果在布局计算后可见项目范围发生更改，则也会调用此回调。在这种情况下，dx和dy将为0。

Parameters
`recyclerView`	`RecyclerView`: The RecyclerView which scrolled.
`dx`	`int`: The amount of horizontal scroll.
`dy`	`int`: The amount of vertical scroll.
