Integration guide

First put the slider view in your layout xml :

        <com.smarteist.autoimageslider.SliderView
                    android:id="@+id/imageSlider"
                    android:layout_width="match_parent"
                    android:layout_height="300dp"
                    app:sliderAnimationDuration="600"
                    app:sliderAutoCycleDirection="back_and_forth"
                    app:sliderAutoCycleEnabled="true"
                    app:sliderIndicatorAnimationDuration="600"
                    app:sliderIndicatorGravity="center_horizontal|bottom"
                    app:sliderIndicatorMargin="15dp"
                    app:sliderIndicatorOrientation="horizontal"
                    app:sliderIndicatorPadding="3dp"
                    app:sliderIndicatorRadius="2dp"
                    app:sliderIndicatorSelectedColor="#5A5A5A"
                    app:sliderIndicatorUnselectedColor="#FFF"
                    app:sliderScrollTimeInSec="1"
                    app:sliderStartAutoCycle="true" />

Or you can put it inside the cardView to look more beautiful :

       <androidx.cardview.widget.CardView
               app:cardCornerRadius="6dp"
               android:layout_margin="16dp"
               android:layout_width="match_parent"
               android:layout_height="wrap_content">

               <com.smarteist.autoimageslider.SliderView
                           android:id="@+id/imageSlider"
                           android:layout_width="match_parent"
                           android:layout_height="300dp"
                           app:sliderAnimationDuration="600"
                           app:sliderAutoCycleDirection="back_and_forth"
                           app:sliderAutoCycleEnabled="true"
                           app:sliderIndicatorAnimationDuration="600"
                           app:sliderIndicatorGravity="center_horizontal|bottom"
                           app:sliderIndicatorMargin="15dp"
                           app:sliderIndicatorOrientation="horizontal"
                           app:sliderIndicatorPadding="3dp"
                           app:sliderIndicatorRadius="2dp"
                           app:sliderIndicatorSelectedColor="#5A5A5A"
                           app:sliderIndicatorUnselectedColor="#FFF"
                           app:sliderScrollTimeInSec="1"
                           app:sliderStartAutoCycle="true" />

       </androidx.cardview.widget.CardView>

Next step

The new version requires an slider adapter plus your custom layout for slider items, Although its very similar to RecyclerView & RecyclerAdapter, and it's familiar and easy to implement this adapter... here is an example for adapter implementation :

public class SliderAdapterExample extends
        SliderViewAdapter<SliderAdapterExample.SliderAdapterVH> {

    private Context context;
    private List<SliderItem> mSliderItems = new ArrayList<>();

    public SliderAdapterExample(Context context) {
        this.context = context;
    }

    public void renewItems(List<SliderItem> sliderItems) {
        this.mSliderItems = sliderItems;
        notifyDataSetChanged();
    }

    public void deleteItem(int position) {
        this.mSliderItems.remove(position);
        notifyDataSetChanged();
    }

    public void addItem(SliderItem sliderItem) {
        this.mSliderItems.add(sliderItem);
        notifyDataSetChanged();
    }

    @Override
    public SliderAdapterVH onCreateViewHolder(ViewGroup parent) {
        View inflate = LayoutInflater.from(parent.getContext()).inflate(R.layout.image_slider_layout_item, null);
        return new SliderAdapterVH(inflate);
    }

    @Override
    public void onBindViewHolder(SliderAdapterVH viewHolder, final int position) {

        SliderItem sliderItem = mSliderItems.get(position);

        viewHolder.textViewDescription.setText(sliderItem.getDescription());
        viewHolder.textViewDescription.setTextSize(16);
        viewHolder.textViewDescription.setTextColor(Color.WHITE);
        Glide.with(viewHolder.itemView)
                .load(sliderItem.getImageUrl())
                .fitCenter()
                .into(viewHolder.imageViewBackground);

        viewHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(context, "This is item in position " + position, Toast.LENGTH_SHORT).show();
            }
        });
    }

    @Override
    public int getCount() {
        //slider view count could be dynamic size
        return mSliderItems.size();
    }

    class SliderAdapterVH extends SliderViewAdapter.ViewHolder {

        View itemView;
        ImageView imageViewBackground;
        ImageView imageGifContainer;
        TextView textViewDescription;

        public SliderAdapterVH(View itemView) {
            super(itemView);
            imageViewBackground = itemView.findViewById(R.id.iv_auto_image_slider);
            imageGifContainer = itemView.findViewById(R.id.iv_gif_container);
            textViewDescription = itemView.findViewById(R.id.tv_auto_image_slider);
            this.itemView = itemView;
        }
    }

}

Custom Slider Image Layout

you can make your own layout for slider view

here is an example for adapter implementation :

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <ImageView
        android:id="@+id/iv_auto_image_slider"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="fitXY" />

    <ImageView
        android:id="@+id/iv_gif_container"
        android:layout_width="80dp"
        android:layout_height="80dp"
        android:layout_gravity="bottom|start"
        android:layout_margin="50dp" />

    <FrameLayout
        android:id="@+id/fl_shadow_container"
        android:background="@drawable/bg_overlay"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom">

        <TextView
            android:id="@+id/tv_auto_image_slider"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="8dp"
            android:layout_marginBottom="25dp"
            android:padding="6dp"
            android:textColor="#FFF"
            android:textSize="18sp" />

    </FrameLayout>

</FrameLayout>

Set the adapter to the Sliderview

After the instantiating of the sliderView (inside the activity or fragment with findViewById|BindView...), set the adapter to the slider.

    SliderView sliderView = findViewById(R.id.imageSlider);
    sliderView.setSliderAdapter(new SliderAdapterExample(context));

You can call this method if you want to start flipping automatically and you can also set up the slider animation :

    sliderView.setIndicatorAnimation(IndicatorAnimationType.WORM);
    sliderView.setSliderTransformAnimation(SliderAnimations.SIMPLETRANSFORMATION);
    sliderView.startAutoCycle();

Elaborate more?

Here is a more realistic and more complete example :


        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            SliderView sliderView = findViewById(R.id.imageSlider);

            SliderAdapterExample adapter = new SliderAdapterExample(this);

            sliderView.setSliderAdapter(adapter);

            sliderView.setIndicatorAnimation(IndicatorAnimationType.WORM); //set indicator animation by using IndicatorAnimationType. :WORM or THIN_WORM or COLOR or DROP or FILL or NONE or SCALE or SCALE_DOWN or SLIDE and SWAP!!
            sliderView.setSliderTransformAnimation(SliderAnimations.SIMPLETRANSFORMATION);
            sliderView.setAutoCycleDirection(SliderView.AUTO_CYCLE_DIRECTION_BACK_AND_FORTH);
            sliderView.setIndicatorSelectedColor(Color.WHITE);
            sliderView.setIndicatorUnselectedColor(Color.GRAY);
            sliderView.setScrollTimeInSec(4); //set scroll delay in seconds :
            sliderView.startAutoCycle();

        }
