Animation

This article demonstrates how to create simple animations and manage their sequence using Aspose.Slides for Android via Java.

Add an Animation

Create a rectangle shape and apply a fade effect triggered on click.

static void addAnimation() {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        IAutoShape shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 100, 100);

        // Fade effect.
        slide.getTimeline().getMainSequence().addEffect(
                shape, EffectType.Fade, EffectSubtype.None, EffectTriggerType.OnClick
        );
    } finally {
        presentation.dispose();
    }
}

Access an Animation

Retrieve the first animation effect from the slide timeline.

static void accessAnimation() {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        IAutoShape shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 100, 100);
        slide.getTimeline().getMainSequence().addEffect(
                shape, EffectType.Fade, EffectSubtype.None, EffectTriggerType.OnClick);

        // Access the first animation effect.
        IEffect effect = slide.getTimeline().getMainSequence().get_Item(0);
    } finally {
        presentation.dispose();
    }
}

Remove an Animation

Remove an animation effect from the sequence.

static void removeAnimation() {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        IAutoShape shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 100, 100);
        IEffect effect = slide.getTimeline().getMainSequence().addEffect(
                shape, EffectType.Fade, EffectSubtype.None, EffectTriggerType.OnClick);

        // Remove the effect.
        slide.getTimeline().getMainSequence().remove(effect);
    } finally {
        presentation.dispose();
    }
}

Sequence Animations

Add multiple effects and demonstrate the order in which animations occur.

static void sequenceAnimations() {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        IAutoShape shape1 = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 100, 100);
        IAutoShape shape2 = slide.getShapes().addAutoShape(ShapeType.Ellipse, 200, 50, 100, 100);

        ISequence sequence = slide.getTimeline().getMainSequence();
        sequence.addEffect(shape1, EffectType.Fly, EffectSubtype.Bottom, EffectTriggerType.OnClick);
        sequence.addEffect(shape2, EffectType.Fly, EffectSubtype.Bottom, EffectTriggerType.OnClick);
    } finally {
        presentation.dispose();
    }
}
