メソッドの詳細

onScrollChanged

void onScrollChanged(int scrollY,
                   boolean firstScroll,
                   boolean dragging)

Called when the scroll change events occurred. This won't be called just after the view is laid out, so if you'd like to initialize the position of your views with this method, you should call this manually or invoke scroll as appropriate.

パラメータ:

scrollY - scroll position in Y axis

firstScroll - true when this is called for the first time in the consecutive motion events

dragging - true when the view is dragged and false when the view is scrolled in the inertia

onDownMotionEvent

void onDownMotionEvent()

Called when the down motion event occurred.

onUpOrCancelMotionEvent

void onUpOrCancelMotionEvent(ScrollState scrollState)

Called when the dragging ended or canceled.

パラメータ:

scrollState - state to indicate the scroll direction
