    android:layout_height="wrap_content"
    app:dotsColor="@color/material_white"
    app:dotsCornerRadius="8dp"
    app:dotsSize="16dp"
    app:dotsSpacing="4dp"
    app:dotsWidthFactor="2.5"
    app:selectedDotColor="@color/md_blue_200"
    app:progressMode="true"
    />

Custom Attributes

Attribute	Description
dotsColor	Color of the dots
selectedDotColor	Color of the selected dot (by default the dotsColor)
progressMode	Lets the selected dot color to the dots behind the current one
dotsSize	Size in dp of the dots (by default 16dp)
dotsSpacing	Size in dp of the space between the dots (by default 4dp)
dotsWidthFactor	The dots scale factor for page indication (by default 2.5)
dotsCornerRadius	The dots corner radius (by default the half of dotsSize for circularity)

In your Java code

    dotsIndicator = (DotsIndicator) findViewById(R.id.dots_indicator);
    viewPager = (ViewPager) findViewById(R.id.view_pager);
    adapter = new ViewPagerAdapter();
    viewPager.setAdapter(adapter);
    dotsIndicator.setViewPager(viewPager);

In your Kotlin code

    val dotsIndicator = findViewById<WormDotsIndicator>(R.id.dots_indicator)
    val viewPager = findViewById<ViewPager>(R.id.view_pager)
    val adapter = ViewPagerAdapter()
    viewPager.adapter = adapter
    dotsIndicator.setViewPager(viewPager)

SpringDotsIndicator

In your XML layout

<com.tbuonomo.viewpagerdotsindicator.SpringDotsIndicator
    android:id="@+id/spring_dots_indicator"
    android:layout_width="wrap_content"

dotsStrokeWidth	The dots stroke width (by default 2dp)
dampingRatio	The damping ratio of the spring force (by default 0.5)
stiffness	The stiffness of the spring force (by default 300)

In your Java code

    springDotsIndicator = (SpringDotsIndicator) findViewById(R.id.spring_dots_indicator);
    viewPager = (ViewPager) findViewById(R.id.view_pager);
    adapter = new ViewPagerAdapter();
    viewPager.setAdapter(adapter);
    springDotsIndicator.setViewPager(viewPager);

In your Kotlin code

    val springDotsIndicator = findViewById<WormDotsIndicator>(R.id.spring_dots_indicator)
    val viewPager = findViewById<ViewPager>(R.id.view_pager)
