Card Slider License Android Arsenal

This is an Android library that implemnts carousel effect with many features and attrs to get exactly what you need.


Demo App

Android app on Google Play

Card Slider components

  1. CardSliderViewPager: Custom ViewPager2 and uses a page transformer to apply carousel effect as shown in GIF.
    • As ViewPager2 is still a final class follow this issue, I added it as part of my package.
  2. CardSliderIndicator: Custom LinearLayout that that contain indicators as children views.
  3. CardSliderAdapter: Abstract class that must be extended and passed to CardSliderViewPager as its adapter.


1- Show preview of pages in left and right (or top and bottom).

2- Can resize (scale) and change opacity of the pages to make focused page larger and more focused in height as shown in GIF (carousel effect).

3- Can make pages auto swiped after specific time.

4- Add indicator and full customize it easily.

5- Infinite indicators like those in the Instagram app.

6- RTL Support.

7- Support vertical orientation.

Add to project

  1. Add it in your root build.gradle at the end of repositories:
    allprojects {
        repositories {
            maven { url '' }
  2. Add the dependency:
    implementation 'com.github.IslamKhSh:CardSlider:{latest_version}'

## Usage 1. Add it to your layout:

    // auto sliding time in seconds
  1. Create your item (page) layout.

  2. Extend CardSliderAdapter ```kotlin class MovieAdapter(private val movies : ArrayList) : CardSliderAdapter() {

    override fun getItemCount() = movies.size

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MovieViewHolder { val view = LayoutInflater.from(parent.context).inflate(R.layout.item_page, parent, false) return MovieViewHolder(view) }

    override fun bindVH(holder: MovieViewHolder, position: Int) { //TODO bind item object with item layout view }

    class MovieViewHolder(view: View) : RecyclerView.ViewHolder(view) }

    or using Java
    java public class MovieAdapter extends CardSliderAdapter {

    private ArrayList movies;

    public MovieAdapter(ArrayList movies){ this.movies = movies; }

    @Override public int getItemCount(){ return movies.getSize(); }

    @Override public MovieViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_page, parent, false); return new MovieViewHolder(view); }

    @Override public void bindVH(int position, MovieViewHolder holder) { //TODO bind item object with item layout view }

    class MovieViewHolder extends RecyclerView.ViewHolder {

    public MovieViewHolder(View view){ super(view); } } } ```

  3. Add adapter to CardSliderViewPager ```kotlin val movies = ArrayList().apply{ // add items to arraylist }

findViewById( = MoviesAdapter(movies)

or using Java
java ArrayList movies = new ArrayList(); // add items to arraylist

CardSliderViewPager cardSliderViewPager = (CardSliderViewPager) findViewById(; cardSliderViewPager.setAdapter(new MoviesAdapter(movies)); ```
