指定者:

onNestedVerticalScrollUnconsumed 在类中 VerticalScrollingBehavior<V extends android.view.View>

参数:

coordinatorLayout - the CoordinatorLayout parent of the view this Behavior is associated with

child - the child view of the CoordinatorLayout this Behavior is associated with

scrollDirection - Direction of the scroll: SCROLL_DIRECTION_UP, SCROLL_DIRECTION_DOWN

currentOverScroll - Unconsumed value, negative or positive based on the direction;

totalScroll - Cumulative value for current direction (Unconsumed)

onNestedVerticalPreScroll

public void onNestedVerticalPreScroll(CoordinatorLayout coordinatorLayout,
                                      V child,

参数:

coordinatorLayout - the CoordinatorLayout parent of the view this Behavior is associated with

child - the child view of the CoordinatorLayout this Behavior is associated with

target - the descendant view of the CoordinatorLayout performing the nested scroll

dx - the raw horizontal number of pixels that the user attempted to scroll

dy - the raw vertical number of pixels that the user attempted to scroll

consumed - out parameter. consumed[0] should be set to the distance of dx that was consumed, consumed[1] should be set to the distance of dy that was consumed

scrollDirection - Direction of the scroll: SCROLL_DIRECTION_UP, SCROLL_DIRECTION_DOWN
