I think we will need to see your layout xml files to be able to see what is going on. It looks like the PageIndicatorView is working correctly but not being displayed from what you've shown

[MichaelJokAr]

this is my xml code

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                xmlns:app="http://schemas.android.com/apk/res-auto"
                android:layout_width="match_parent"
                android:layout_height="230dp"
                android:background="@android:color/white"
                android:orientation="vertical">

    <android.support.v4.view.ViewPager
        android:id="@+id/viewPager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

    <View
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:alpha="0.15"
        android:background="#000000"/>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:gravity="center"
        android:orientation="vertical">

        <TextView
            android:id="@+id/tvTitle"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:ellipsize="end"
            android:maxLines="2"
            android:padding="10dp"
            android:text=""
            android:textColor="@android:color/white"
            android:textSize="20dp"/>

        <com.rd.PageIndicatorView
            android:id="@+id/pageIndicatorView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginBottom="10dp"
            app:piv_animationType="drop"
            app:piv_padding="5dp"
            app:piv_radius="4dp"
            />
    </LinearLayout>

</RelativeLayout>

and this is the viewPagerAdapter code

class TopStoryAdapter(var context: Context,
                      var viewList: ArrayList<View>,
                      var transformer: LifecycleTransformer<Any>,
                      var topStories: ArrayList<TopStoryEntity>) : PagerAdapter() {
    var itemClickListener: AdapterItemClickListener? = null

    override fun instantiateItem(collection: ViewGroup, position: Int): Any {
        val view = viewList[position]
        var image: ImageView = view.findViewById(R.id.image) as ImageView

        ImageLoader.loadImage(context,
                topStories[position].image,
                R.mipmap.image_small_default,
                image!!)
        ViewUtils.viewClick(image, transformer,
                Consumer<Any> {
                    itemClickListener?.itemClickListener(position)
                })
        collection.addView(view)
        return view
    }

    override fun destroyItem(collection: ViewGroup, position: Int, view: Any) {
        collection.removeView(view as View)
    }

    override fun getCount(): Int {
        return viewList.size
    }

    override fun isViewFromObject(view: View, `object`: Any): Boolean {
        return view === `object`
    }

    override fun getItemPosition(`object`: Any?): Int {
        return PagerAdapter.POSITION_NONE
    }

}

I use this layout as a headItem in recyclerView; and the source code is here

I'm not sure if this can help you, but I set the viewPager by the XML and its working over here... Also, in Kotlin you can avoid to call find(YourViewID). Check it here: https://stackoverflow.com/a/34448660/7806488
