Best Android PageIndicator Libraries - 2021

ViewPager2 or ViewPager is such a vital component in android development. One of the most unique features of mobile apps as opposed to desktop ones is navigation through hand gestures like swiping. At the heart of this in android is the ViewPager or ViewPager2.

However we do need indicators to show us the current page. If you were just swiping without any tabs or indicators you would not know the current page you are in. So page indicators are just simple shapes like dots that show us the current page. You generally can see such shapes for example in galleries in web apps. Users can even navigate via such dots.

This tutorial explores the best page indicators to use. We do not list them in an important order, instead we list them as we find them, with the first being the first to be discovered as opposed to the best one.

(a). ViewpagerDots

Simple, compact Kotlin library for ViewPager page indicators.

This library provides a very small, compact, Kotlin-based implementation for ViewPager dots. The dots can of course be switched out for whatever type of Drawable you wish. The animation can be customized as well.

Here is an example of these dots in action:

ViewPager Dots

Here is how you use this library:

Step 1: Install it

In your build.gradle add the following implementation statement then sync:

 implementation 'com.afollestad:viewpagerdots:1.0.0'

Add to Layout

Add ViewPager2 or ViewPager to your layout as follows:





Here are some of the customizations you can make declaratively in your layout:

  • app:dot_width (the width of each individual dot)
  • app:dot_height (the height of each individual dot)
  • app:dot_margin (spacing between each dot)
  • app:dot_drawable (the default icon for each dot)
  • app:dot_drawable_unselected (defaults to dot_drawable)
  • app:dot_tint (lets you apply a color tint to the above drawables)
  • app:dots_animator (the animator when a dot becomes selected)
  • app:dots_animator_reverse (defaults to reversed version of the above)
  • app:dots_orientation (orientation of the whole strip; defaults to horizontal)
  • app:dots_gravity (gravity of the whole strip; defaults to center)

You can also apply some basic changes dynamically in your code:

Step 3: Attach ViewPager2 to Page Indicator

In your code, you can attach the ViewPager or ViewPager2 to your DotsIndicator using the attachViewPager() function that is provided the DotsIndicator:

val viewPager: ViewPager = // ...
val dots: DotsIndicator = // ...

viewPager.adapter = // ... This must be set before attaching

We had seen how to customize the dots indicator declaratively, here's how you can customize them imperatively via code:

val dots: DotsIndicator = // ...

// This lets you switch out the indicator drawables at runtime.
  indicatorRes = R.drawable.some_drawable,
  unselectedIndicatorRes = R.drawable.other_drawable // optional, defaults to above

// These two let you dynamically tint your indicators at runtime.

(b). PageIndicator

An Instagram like page indicator compatible with RecyclerView and ViewPager.

Here's an example of it in usage with both recyclerview and viewpager:

PageIndicator example

So how do you use it?

Step 1: Install it

You need to add jitpack to your root level build.gradle as follows:

allprojects {
  repositories {
    maven { url '' }

Then add the implementation statement in your app level build.gradle as follows:

dependencies {
  implementation 'com.github.chahine:pageindicator:0.2.8'

Step 2: Add to Layout

Next you need to add it to your xml layout. Here's it's code:


Step 3: Attach to RecyclerView or ViewPager

The third step is to attach it to your recyclerview or viewpager. To either, simply invoke the attachTo() function and pass either the Recyclerview or Viewpager.

For Recyclerview:


By default, attaching to a RecyclerView will end up updating the pageIndicator when the most visible item position changes and expect the RecyclerView items to have the same width. If you would like to customize this behavior, add a scroll listener to your RecyclerView and use PageIndicator::swipeNext and PageIndicator::swipePrevious; and set the pageIndicator's count

For ViewPager:


If you would like to programmatically move to the next or previous item in the ViewPager or RecyclerView, use the following methods:
