           android:layout_width="match_parent"
           android:layout_height="wrap_content"

           android:layout_marginTop="24dp"

           app:cardSlider_otherPagesWidth="24dp" // width of displayed parts of left and right pages
           app:cardSlider_pageMargin="12dp" // margin between pages
           app:cardSlider_cardCornerRadius="5dp"/> // corner radius of every page
  1. Extend CardSliderAdapter
class MovieAdapter(movies : ArrayList<Movie>) : CardSliderAdapter<Movie>(movies) {

    override fun bindView(position: Int, itemContentView: View, item: Movie?) {
      //TODO bind item object with item layout view
    }

    override fun getItemContentLayout(position: Int) : Int {
        //TODO return the item layout of every position 
        //This layout will be added as a child of CardView
    }
}

or using Java

public class MovieAdapter extends CardSliderAdapter<Movie> {
    
    public MovieAdapter(ArrayList<Movie> movies){
        super(movies);
    }
    
    @Override
    public void bindView(int position, View itemContentView, Movie item) {
      //TODO bind item object with item layout view
    }

    @Override
    public int getItemContentLayout(int position) {
        //TODO return the item layout of every position 
        //This layout will be added as a child of CardView
    }
}
  1. Create item layout to return it in getItemContentLayout

  2. Add adapter to CardSliderViewPager

  val movies = ArrayList<Movie>().apply{
  // add items to arraylist
  }
  
  findViewById<CardSliderViewPager>(R.id.viewPager).adapter = MoviesAdapter(movies)

or using Java

  ArrayList<Movie> movies = ArrayList<Movie>();
    // add items to arraylist
  
  CardSliderViewPager cardSliderViewPager = (CardSliderViewPager) findViewById(R.id.viewPager);
  cardSliderViewPager.setAdapter(MoviesAdapter(movies));

            android:layout_height="wrap_content"
            android:id="@+id/indicator"/>
