Class OverScrollBounceEffectDecoratorBase.OverScrollingState

java.lang.Object

me.everything.android.ui.overscroll.OverScrollBounceEffectDecoratorBase.OverScrollingState

All Implemented Interfaces:

OverScrollBounceEffectDecoratorBase.IDecoratorState

Enclosing class:

OverScrollBounceEffectDecoratorBase

protected class OverScrollBounceEffectDecoratorBase.OverScrollingState
extends java.lang.Object
implements OverScrollBounceEffectDecoratorBase.IDecoratorState

Handles the actual over-scrolling: thus translating the view according to configuration and user interactions, dynamically.

The state is exited - thus completing over-scroll handling, in one of two cases:
When user lets go of the view, it transitions control to the bounce-back state.
When user moves the view back onto a potential 'under-scroll' state, it abruptly transitions control to the idle-state, so as to return touch-events management to the normal over-scroll-less environment (thus preventing under-scrolling and potentially regaining regular scrolling).
