Question 1

How to add DotsIndicator to ViewPager2 in Android?

Accepted Answer

In XML, define the indicator and call attachTo(viewPager2) in Kotlin code. For Jetpack Compose, use the DotsIndicator composable with rememberPagerState. The README provides complete examples for both approaches.

Question 2

DotsIndicator vs TabLayout for pager navigation

Accepted Answer

DotsIndicator focuses on animated dot indicators with multiple visual styles, ideal for minimalist designs. TabLayout offers tab-based navigation with text and icons, better for labeled sections. Choose based on your UI needs.

Question 3

How to change the dot color in DotsIndicator programmatically?

Accepted Answer

In XML, use attributes like dotsColor and selectedDotColor. In Kotlin, set properties after initialization. For Compose, pass color parameters in DotGraphic within the indicator type, as shown in the code snippets.

Question 4

Does DotsIndicator work with dynamic page counts?

Accepted Answer

Yes, in Compose, bind dotCount to a mutable state variable. In XML, the indicator updates automatically when the ViewPager adapter changes, as demonstrated in the attachTo method examples.

Question 5

How to implement a worm animation in DotsIndicator for Compose?
