Using page indicators, you can help your users understand their current position within your app's content, providing a visual indication of progress. These navigational cues are useful when you present content sequentially, such as carousel implementations, image galleries and slideshows, or pagination in lists.

## Results

**Figure 1.**Pager showing a circle indicator under the content.

## Version compatibility

This implementation requires that your project minSDK be set to API level 21 or higher.

### Dependencies

### Kotlin

<br />

```kotlin
  implementation(platform("androidx.compose:compose-bom:2025.10.01"))
  
```

<br />

### Groovy

<br />

```groovy
  implementation platform('androidx.compose:compose-bom:2025.10.01')
  
```

## Create a horizontal pager with a custom page indicator

The following code creates a horizontal pager that has a page indicator, giving the user visual cues for how many pages there are and which page is visible:

<br />

```kotlin
val pagerState = rememberPagerState(pageCount = {
    4
})
HorizontalPager(
    state = pagerState,
    modifier = Modifier.fillMaxSize()
) { page ->
    // Our page content
    Text(
        text = "Page: $page",
    )
}
Row(
    Modifier
        .wrapContentHeight()
        .fillMaxWidth()
        .align(Alignment.BottomCenter)
        .padding(bottom = 8.dp),
    horizontalArrangement = Arrangement.Center
) {
    repeat(pagerState.pageCount) { iteration ->
        val color = if (pagerState.currentPage == iteration) Color.DarkGray else Color.LightGray
        Box(
            modifier = Modifier
                .padding(2.dp)
                .clip(CircleShape)
                .background(color)
                .size(16.dp)
        )
    }

### Key points about the code

- The code implements a[`HorizontalPager`](https://developer.android.com/reference/kotlin/androidx/compose/foundation/pager/package-summary#HorizontalPager(androidx.compose.foundation.pager.PagerState,androidx.compose.ui.Modifier,androidx.compose.foundation.layout.PaddingValues,androidx.compose.foundation.pager.PageSize,kotlin.Int,androidx.compose.ui.unit.Dp,androidx.compose.ui.Alignment.Vertical,androidx.compose.foundation.gestures.TargetedFlingBehavior,kotlin.Boolean,kotlin.Boolean,kotlin.Function1,androidx.compose.ui.input.nestedscroll.NestedScrollConnection,androidx.compose.foundation.gestures.snapping.SnapPosition,kotlin.Function2)), which lets you swipe horizontally between different pages of content. In this case, each page displays the page number.
- The`rememberPagerState()`function initializes the pager and sets the number of pages to 4. This function creates a state object that tracks the current page, and lets you control the pager.
- The[`pagerState.currentPage`](https://developer.android.com/reference/kotlin/androidx/compose/foundation/pager/PagerState#currentPage())property is used to determine which page indicator should be highlighted.
- The page indictator appears in a pager overlaid by a[`Row`](https://developer.android.com/reference/kotlin/androidx/compose/foundation/layout/package-summary#Row(androidx.compose.ui.Modifier,androidx.compose.foundation.layout.Arrangement.Horizontal,androidx.compose.ui.Alignment.Vertical,kotlin.Function1))implementation.
- A 16 dp circle is drawn for each page in the pager. The indicator for the current page is displayed as`DarkGray`, while the rest of the indicator circles are`LightGray`.
- The[`Text`](https://developer.android.com/reference/kotlin/androidx/compose/material/package-summary#Text(androidx.compose.ui.text.AnnotatedString,androidx.compose.ui.Modifier,androidx.compose.ui.graphics.Color,androidx.compose.ui.unit.TextUnit,androidx.compose.ui.text.font.FontStyle,androidx.compose.ui.text.font.FontWeight,androidx.compose.ui.text.font.FontFamily,androidx.compose.ui.unit.TextUnit,androidx.compose.ui.text.style.TextDecoration,androidx.compose.ui.text.style.TextAlign,androidx.compose.ui.unit.TextUnit,androidx.compose.ui.text.style.TextOverflow,kotlin.Boolean,kotlin.Int,kotlin.Int,kotlin.collections.Map,kotlin.Function1,androidx.compose.ui.text.TextStyle))composable within the`HorizontalPager`displays the text "Page: \[page number\]" on each page.
