Screenshot

Gradle via JitPack

Add it in your root build.gradle at the end of repositories:

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

Add the dependency

dependencies {
    implementation 'com.github.BakerJQ:Android-InfiniteCards:1.0.5'
}

Attrs

• animType : animation type
  • front : move the selected card to first
  • switchPosition : move the selected card to first, and the first card to the selected position
  • frontToLast : move the first card to last position
• cardRatio : ratio of the card
• animDuration : duration of each card's animation
• animAddRemoveDelay : delay of animation of add and remove between each card
• animAddRemoveDuration : duration of add and remove each card's animation

How to use

layout in xml

<com.bakerj.infinitecards.InfiniteCardView
        android:id="@+id/view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        infiniteCard:animDuration="1000"
        infiniteCard:cardRatio="1"/>

Set Adapter

Just extends the BaseAdapter

class MyAdapter extends BaseAdapter{
  ...
}
mAdapter = new MyAdapter(resId);
mCardView.setAdapter(mAdapter);

Animation transformers and interpolators

Default

If you just use all default animations, just do nothing.

mCardView.setAnimInterpolator(new LinearInterpolator());
mCardView.setTransformerToFront(new DefaultTransformerToFront());
mCardView.setTransformerToBack(new DefaultTransformerToBack());
mCardView.setZIndexTransformerToBack(new DefaultZIndexTransformerCommon());

Customisation

mCardView.setTransformerToBack(new AnimationTransformer() {
    @Override
    public void transformAnimation(View view, float fraction, int cardWidth, int cardHeight, int fromPosition, int toPosition) {
        int positionCount = fromPosition - toPosition;
        float scale = (0.8f - 0.1f * fromPosition) + (0.1f * fraction * positionCount);
        ViewHelper.setScaleX(view, scale);
        ViewHelper.setScaleY(view, scale);
        if (fraction < 0.5) {
            ViewCompat.setRotationX(view, 180 * fraction);
        } else {
            ViewCompat.setRotationX(view, 180 * (1 - fraction));
        }
    }

    @Override
    public void transformInterpolatedAnimation(View view, float fraction, int cardWidth, int cardHeight, int fromPosition, int toPosition) {
        int positionCount = fromPosition - toPosition;
        float scale = (0.8f - 0.1f * fromPosition) + (0.1f * fraction * positionCount);
        ViewHelper.setTranslationY(view, -cardHeight * (0.8f - scale) * 0.5f - cardWidth * (0.02f *
                fromPosition - 0.02f * fraction * positionCount));
    }
});
mCardView.setZIndexTransformerToBack(new ZIndexTransformer() {
    @Override
    public void transformAnimation(CardItem card, float fraction, int cardWidth, int cardHeight, int fromPosition, int toPosition) {
        if (fraction < 0.4f) {
            card.zIndex = 1f + 0.01f * fromPosition;
        } else {
            card.zIndex = 1f + 0.01f * toPosition;
        }
    }

    @Override
    public void transformInterpolatedAnimation(CardItem card, float fraction, int cardWidth, int cardHeight, int fromPosition, int toPosition) {

    }
});
