iPhone Slide Effect in BlackBerry

Introduction

This article introduces the famous iPhone Master/Details Screens slide effect, to be applied in BlackBerry platform.

Using the Code

Our first screen "FirstScreen.java" (Master) only contains clickable fields (i.e. ButtonFields) that will push the details screen.

In the "SecondScreen.java" (Details), we should register in the constructor of the screen; how the screen will be pushed and pop: and defining the Transition Type, Speed (Duration), and Direction:

//Entering Transition
TransitionContext transition = new TransitionContext(TransitionContext.TRANSITION_SLIDE);
transition.setIntAttribute(TransitionContext.ATTR_DURATION, 500);
transition.setIntAttribute(TransitionContext.ATTR_DIRECTION,TransitionContext.DIRECTION_LEFT);
transition.setIntAttribute(TransitionContext.ATTR_STYLE,TransitionContext.STYLE_OVER);

UiEngineInstance engine = Ui.getUiEngineInstance();
engine.setTransition(null, this, UiEngineInstance.TRIGGER_PUSH,transition);

// Leaving Transition
transition = new TransitionContext(TransitionContext.TRANSITION_SLIDE);
transition.setIntAttribute(TransitionContext.ATTR_DURATION, 500);
transition.setIntAttribute(TransitionContext.ATTR_DIRECTION,TransitionContext.DIRECTION_RIGHT);
transition.setIntAttribute(TransitionContext.ATTR_STYLE,TransitionContext.STYLE_PUSH);
        
engine.setTransition(this, null, UiEngineInstance.TRIGGER_POP,transition);
