How to

Gradle

repositories {
    google()
    mavenCentral()
}

dependencies {
    implementation("com.tbuonomo:dotsindicator:5.0")
}

For Jetpack Compose

Column {
    var pageCount by remember { mutableStateOf(5) }
    val pagerState = rememberPagerState()
    HorizontalPager(
        modifier = Modifier.padding(top = 24.dp),
        pageCount = pageCount,
        contentPadding = PaddingValues(horizontal = 64.dp),
        pageSpacing = 24.dp,
        state = pagerState
    ) {
        PagePlaceholderItem()
    }
    DotsIndicator(
        dotCount = pageCount,
        type = ShiftIndicatorType(dotsGraphic = DotGraphic(color = MaterialTheme.colorScheme.primary)),
        pagerState = pagerState
    )
}

4 types are available in JetpackCompose

ShiftIndicatorType

DotsIndicator(
    dotCount = pageCount,
    type = ShiftIndicatorType(dotsGraphic = DotGraphic(color = MaterialTheme.colorScheme.primary)),
    pagerState = pagerState
)

SpringIndicatorType

DotsIndicator(
    dotCount = pageCount,
    type = SpringIndicatorType(
        dotsGraphic = DotGraphic(
            16.dp,
            borderWidth = 2.dp,
            borderColor = MaterialTheme.colorScheme.primary,
            color = Color.Transparent
        ),
        selectorDotGraphic = DotGraphic(
            14.dp,
            color = MaterialTheme.colorScheme.primary
        )
    ),
    pagerState = pagerState
)

WormIndicatorType

DotsIndicator(
    dotCount = pageCount,
    type = WormIndicatorType(
        dotsGraphic = DotGraphic(
            16.dp,
            borderWidth = 2.dp,
            borderColor = MaterialTheme.colorScheme.primary,
            color = Color.Transparent,
        ),
        wormDotGraphic = DotGraphic(
            16.dp,
            color = MaterialTheme.colorScheme.primary,
        )
    ),
    pagerState = pagerState
)

BalloonIndicatorType

DotsIndicator(
    dotCount = pageCount,
    type = BalloonIndicatorType(
        dotsGraphic = DotGraphic(
            color = MaterialTheme.colorScheme.primary,
            size = 8.dp
        ),
        balloonSizeFactor = 2f
    ),
    dotSpacing = 20.dp,
    pagerState = pagerState
)

For XML

DotsIndicator

In your XML layout

Custom Attributes

Attribute	Description
