Create an auto Image Slider activity in android.

Add dependency in your gradle file:

//for ViewPager2
implementation "androidx.viewpager2:viewpager2:1.0.0"
//for RoundImage
implementation 'com.makeramen:roundedimageview:2.3.0'

activity_main.xml :

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    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:background="#FFFFFF"
    tools:context=".MainActivity">

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="110dp"
        android:src="@drawable/logo"/>

    <androidx.viewpager2.widget.ViewPager2
        android:id="@+id/ViewPager2"
        android:layout_width="match_parent"
        android:layout_height="480dp"
        android:layout_centerInParent="true"
        android:layout_marginStart="70dp"/>

    <Button
        android:id="@+id/GoToPhone"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/ViewPager2"
        android:layout_marginTop="10dp"
        android:text="Continue With Phone Number"
        android:background="@drawable/button_custom"
        android:drawableRight="@drawable/rightarrow"
        android:onClick="VerifyPhoneNumber"
        />

</RelativeLayout>

Create a XML file name with slide_item_container:

<?xml version="1.0" encoding="utf-8"?>
<com.makeramen.roundedimageview.RoundedImageView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/ImageSlide"
    app:riv_corner_radius="12dp"
    android:adjustViewBounds="true">

</com.makeramen.roundedimageview.RoundedImageView>

Create a Java class name with Slide_item:
public class SlideItem {
    //here you can use string variable to store url
    //if you want to load image from internet
    private int images;
    SlideItem(int images)
    {
        this.images=images;
    }
    public int getImages() {
        return images;
    }
}
Create a sliderAdapter.java class:
public class SliderAdapter extends RecyclerView.Adapter<SliderAdapter.SliderHolder>{
    private List<SlideItem> slideItems;
    private ViewPager2 viewPager2;

  SliderAdapter(List<SlideItem> slideItems, ViewPager2 viewPager2) {
        this.slideItems = slideItems;
        this.viewPager2 = viewPager2;
    }

    @NonNull
    @Override
    public SliderHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        return new SliderHolder(
                LayoutInflater.from(parent.getContext()).inflate(
                        R.layout.slide_item_container,
                        parent,
                        false
                )
        );
    }

    @Override
    public void onBindViewHolder(@NonNull SliderHolder holder, int position) {
        holder.setImages(slideItems.get(position));
        if(position==slideItems.size()-2){
            viewPager2.post(runnable);

        }
    }

    @Override
    public int getItemCount() {
        return slideItems.size();
    }

    class SliderHolder extends RecyclerView.ViewHolder{
        private RoundedImageView imageView;
        SliderHolder(@NonNull View itemView) {
            super(itemView);
            imageView=itemView.findViewById(R.id.ImageSlide);
        }
        void setImages(SlideItem slideItem){
            //if necessary to display images from internet we have to
            // add code here with help of glide

            imageView.setImageResource(slideItem.getImages());
        }
    }
    private Runnable runnable=new Runnable() {
        @Override
        public void run() {
            slideItems.addAll(slideItems);
            notifyDataSetChanged();
        }
    };
}

Main_Activity.java:

public class MainActivity extends AppCompatActivity {
    private ViewPager2 viewPager2;
    private Handler sliderHandle=new Handler();


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        viewPager2=findViewById(R.id.ViewPager2);

        //list of images from drawable
        List<SlideItem> slideItems=new ArrayList<>();
        slideItems.add(new SlideItem(R.drawable.pic1));
        slideItems.add(new SlideItem(R.drawable.pic2));
        slideItems.add(new SlideItem(R.drawable.pic));
        slideItems.add(new SlideItem(R.drawable.pic2));
        slideItems.add(new SlideItem(R.drawable.pic1));

        viewPager2.setAdapter(new SliderAdapter(slideItems,viewPager2));

        viewPager2.setClipToPadding(false);
        viewPager2.setClipChildren(false);
        viewPager2.setOffscreenPageLimit(3);
        viewPager2.getChildAt(0).setOverScrollMode(RecyclerView.OVER_SCROLL_NEVER);

        CompositePageTransformer compositePageTransformer=new CompositePageTransformer();
        compositePageTransformer.addTransformer(new MarginPageTransformer(40));
        compositePageTransformer.addTransformer(new ViewPager2.PageTransformer() {
            @Override
            public void transformPage(@NonNull View page, float position) {
                float r=1-Math.abs(position);
                page.setScaleY(0.85f + r+0.15f);
            }
        });

        viewPager2.setPageTransformer(compositePageTransformer);
        viewPager2.registerOnPageChangeCallback(new ViewPager2.OnPageChangeCallback() {
            @Override
            public void onPageSelected(int position) {
                super.onPageSelected(position);
                sliderHandle.removeCallbacks(sliderRunable);
                sliderHandle.postDelayed(sliderRunable,2000);  //slider duration 3 sec
            }
        });
    }
    private Runnable sliderRunable=new Runnable() {
        @Override
        public void run() {
            viewPager2.setCurrentItem(viewPager2.getCurrentItem()+1);
        }
    };

    public void VerifyPhoneNumber(View view) {
        Intent intent=new Intent(MainActivity.this, PhoneVerification.class);
        startActivity(intent);
    }
