Interface Transition

All Known Implementing Classes:

FadeTransition, SlideTransition

public interface Transition

Animates the replacement of the outgoing content by the incoming content during a navigation.

A transition is a parameterized object, not an enum constant, so an application can configure the shipped transitions (SlideTransition, FadeTransition) or supply its own. The instant transition IMMEDIATE performs no animation and is the Navigator's initial default.

run(TransitionContext, TransitionListener) is called on the MicroUI thread after the navigation has been committed. The transition animates using the TransitionContext primitives and must call TransitionListener.onTransitionEnd() exactly once when it finishes.

Since:

0.2.0

Field Detail

DEFAULT_DURATION_MILLIS

static final int DEFAULT_DURATION_MILLIS

Default duration of the shipped animated transitions (FadeTransition, SlideTransition), in milliseconds.

Constant Field Values

IMMEDIATE

static final Transition IMMEDIATE

The instant transition: the incoming content replaces the outgoing content in a single frame.

This is the Navigator's initial default transition; it reproduces a non-animated page change. It performs no animation and signals completion synchronously, so the outgoing content is detached immediately.

Method Detail

run

void run(TransitionContext context,
         TransitionListener listener)

Animates the page change described by the given context.

Called on the MicroUI thread once per navigation. The implementation must call TransitionListener.onTransitionEnd() exactly once when the animation is finished.

Parameters:

context - the stage exposing the contents, the content area size, and the animation primitives.

listener - the listener to notify once, when the transition finishes.
