Showcase Layout Compose

Create beautiful animated showcase effects for your compose UIs easily!

Now with multiplatform support and two different showcase layouts to choose from:

  • ShowcaseLayout: Classic full-screen overlay with cutouts
  • TargetShowcaseLayout: Modern targeted highlighting with customizable shapes

Demo

Lumen Bank onboarding tour

More tours: Now Playing and Messages

Now Playing onboarding tour     Messages onboarding tour

The demo app ships three small apps, each with an onboarding tour built on the library, plus a playground that exposes every parameter. Try it in your browser or jump straight into a tour:

Scenario What it shows Source
Lumen Bank · open TargetShowcaseLayout morphing between a card and a round button, custom message cards, and a locked "tap the eye icon to continue" step BankingScreen.kt
Now Playing · open A dark UI with a light overlay, TargetShape.CIRCLE, the pulse ring, and a locked step on the play button MusicScreen.kt
Messages · open ShowcaseLayout with a locked step on a text field: the keyboard works under the overlay and the tour continues once a message is sent ChatScreen.kt

The three demo scenarios: Lumen Bank, Now Playing and Messages

Every scenario can be switched between the two layouts from its menu, and &autoplay=1 on any of the links above plays the tour hands-free. The message cards are ordinary composables, see TourUi.kt.

Setup

Showcase Layout Compose can be used in both Jetpack Compose (native Android) or Compose Multiplatform (Kotlin Multiplatform) projects.

Compose multiplatform support starts at version 1.0.5-alpha-8 and up.

Add the dependency to your module's build.gradle file like below

implementation("ly.com.tahaben:showcase-layout-compose:{latest-version}")

Latest version Maven Central or see Releases.

Usage

Step 1

Create a ShowcaseLayout and make it the root composable (put all screen composables inside it)

    var isShowcasing by remember {
    mutableStateOf(true)
}
ShowcaseLayout(
    isShowcasing = isShowcasing,
    onFinish = { isShowcasing = false }
) {
    // screen content here
    Column(
        modifier = Modifier
            .fillMaxSize()
    ) {
        Text(text = "ShowcaseLayout Test 1")
        Spacer(modifier = Modifier.height(16.dp))
        Text(text = "ShowcaseLayout Test 2")
        Spacer(modifier = Modifier.height(16.dp))
        Text(text = "ShowcaseLayout Test 3")
    }
}

Step 2

In composables you want to showcase on the modifier use Modifier.showcase(), Lets say we want to showcase the first text "ShowcaseLayout Test 1"

Text(
    modifier = Modifier.showcase(
        // should start with 1 and increment with 1 for each time you use Modifier.showcase()
        index = 1,
        message = ShowcaseMsg(
            "This is a showcase message",
            textStyle = TextStyle(color = Color.White)
        )
    ),
    text = "ShowcaseLayout Test 1"
)

you also use the old method by wrap the composables you want to showcase with Showcase()

Step 3

You have 2 ways of showcasing, showcase everything subsequently or showcasing each item manually

Showcase all items subsequently Start showcasing by making isShowcasing = true, and stop showcasing by making it false above we stop showcasing after we showcase the last item using `onFinished` which is called whenever all items are showcased,
Showcase a single item (1.0.5 and up) After you attach the index and showcase message to your components you can simply call showcaseItem(i) where i is the index of the item you want to showcase
    val coroutineScope = rememberCoroutineScope()

    coroutineScope.launch{
        showcaseItem(1)
    }

similarly you can show a greeting using showGreeting and passing the message

    val coroutineScope = rememberCoroutineScope()

    coroutineScope.launch{
        showGreeting(
            ShowcaseMsg(
            text = "I like compose bro <3",
            textStyle = TextStyle(color = Color.White)
            )
        )
    }

Done, our text is now showcased!, customize it further with Additional parameters.

TargetShowcaseLayout (New!)

Starting from version 1.0.6, Showcase Layout Compose now offers a new layout option: TargetShowcaseLayout. This layout provides a different visual approach to showcasing UI elements by highlighting specific targets with customizable shapes rather than the full-screen approach of the original ShowcaseLayout.

Key Features

  • Highlights target elements with customizable shapes (circle, rectangle, or rounded rectangle)
  • Smooth animations between targets
  • Pulsing effect around the target for better visibility
  • All the same customization options as the original ShowcaseLayout

Usage

You can use TargetShowcaseLayout directly:

var isShowcasing by remember { mutableStateOf(true) }

TargetShowcaseLayout(
    isShowcasing = isShowcasing,
    onFinish = { isShowcasing = false },
    targetShape = TargetShape.ROUNDED_RECTANGLE, // CIRCLE, RECTANGLE, or ROUNDED_RECTANGLE
    cornerRadius = 8.dp, // Only used with ROUNDED_RECTANGLE
    animateToNextTarget = true, // Smooth animation between targets
    greeting = ShowcaseMsg(
        "Welcome to TargetShowcaseLayout!",
        textStyle = TextStyle(color = Color.White)
    )
) {
    // Your UI content here
    Column {
        Text(
            modifier = Modifier.showcase(
                index = 1,
                message = ShowcaseMsg(
                    "This element is highlighted with TargetShowcaseLayout",
                    textStyle = TextStyle(color = Color.White)
                )
            ),
            text = "Target Showcase Example"
        )
    }
}

TargetShowcaseLayout Parameters

In addition to the parameters shared with ShowcaseLayout, TargetShowcaseLayout offers:

TargetShowcaseLayout(
    // Common parameters (same as ShowcaseLayout)
    isShowcasing = isShowcasing,
    colors = ShowcaseLayoutDefaults.colors(),
    initIndex = 0,
    animationDuration = 1000,
    onFinish = { isShowcasing = false },
    greeting = ShowcaseMsg(
        "Welcome to TargetShowcaseLayout!",
        textStyle = TextStyle(color = Color.White)
    ),
    lineThickness = 5.dp,

    // TargetShowcaseLayout specific parameters
    targetShape = TargetShape.CIRCLE, // CIRCLE, RECTANGLE, or ROUNDED_RECTANGLE
    cornerRadius = 8.dp, // Only used with ROUNDED_RECTANGLE
    animateToNextTarget = true // Smooth animation between targets, otherwise shrink and expand on each target
) {
    // Your UI content here
}

The same banking screen on TargetShowcaseLayout (left) and ShowcaseLayout (right):

Additional parameters

colors

Controls the color and alpha of the dimming overlay (and, for TargetShowcaseLayout, the color of the pulsing ring). Build a ShowcaseLayoutDefaults.Colors with ShowcaseLayoutDefaults.colors(...). The overlay color's own alpha is honored, so you have full control over transparency. The default is Color.Black.copy(alpha = 0.9f); for a dark UI, pass a light overlay color.

ShowcaseLayout(
    isShowcasing = isShowcasing,
    onFinish = { isShowcasing = false },
    colors = ShowcaseLayoutDefaults.colors(
        overlayColor = Color.White.copy(alpha = 0.9f), // light overlay for a dark UI
        pulseColor = Color.White                       // TargetShowcaseLayout only
    )
)

Migrating from isDarkLayout: the isDarkLayout parameter is deprecated and will be removed in a future release. Replace isDarkLayout = true with colors = ShowcaseLayoutDefaults.colors(overlayColor = Color.White.copy(alpha = 0.9f)). Leaving colors at its default reproduces the previous isDarkLayout = false look.

overlayColor = Color.White.copy(alpha = 0.9f)
Screenshot Light overlay example

greeting

A customizable greeting message of type showcaseMsg()

ShowcaseLayout(
    isShowcasing = isShowcasing,
    onFinish = { isShowcasing = false },
    greeting = ShowcaseMsg(
        "Welcome to my app, lets take you on a quick tour!, tap anywhere to continue",
        textStyle = TextStyle(color = Color.White)
    )
)

Greeting msg example

initIndex

the initial value of what index will showcase first.

animationDuration

total animation time taken when switching from current to next target in milliseconds(default is 1000ms).

    val greetingString = buildAnnotatedString {
    append("Welcome to ")
    pushStyle(SpanStyle(fontWeight = FontWeight.Bold))
    append("My App")
    pop()
    append(", let's take you on a quick tour!")
    pushStyle(SpanStyle(fontWeight = FontWeight.Bold))
    append("\n Tap anywhere")
    pop()
    append(" to continue")
}
ShowcaseLayout(
    isShowcasing = isShowcasing,
    onFinish = { isShowcasing = false },
    greeting = ShowcaseMsg(
        text = greetingString, // You can use an annotated string or a normal string here
        textStyle = TextStyle(color = Color.White, textAlign = TextAlign.Center)
    ),
    animationDuration = 1000
) 

advanceOnTargetTapOnly

By default a tap anywhere on the screen advances to the next target (or dismisses the showcase). Set advanceOnTargetTapOnly = true to only advance when the user taps inside the highlighted target shape — taps elsewhere are ignored. Useful when you want the user to actually interact with (or notice) the highlighted element before moving on. The greeting/initial screen still advances on any tap. Defaults to false. Available on both ShowcaseLayout and TargetShowcaseLayout.

ShowcaseLayout(
    isShowcasing = isShowcasing,
    onFinish = { isShowcasing = false },
    advanceOnTargetTapOnly = true
)

canProceed (locked steps)

Starting from version 1.2.0 a step can be locked until the user does something: taps a specific button, types a valid value, toggles a switch, ... Pass canProceed = false to Modifier.showcase() (or Showcase()) and the step behaves like this:

  • Tapping the overlay no longer advances or dismisses the showcase.
  • Touches inside the target's bounds go straight to the target, as if the overlay was not there: a text field gets focus and the soft keyboard opens, a button clicks, a list scrolls. Touches outside the target are still swallowed.
  • As soon as canProceed becomes true the showcase advances by itself (or dismisses the item when showing a single item with showcaseItem()).

canProceed is a plain Boolean, so read it from snapshot state and let recomposition do the rest. Pair it with onProceed, which is called once when the showcase leaves the step, to clean up after it, for example to hide the soft keyboard the step opened so users (iOS in particular) are not left with it on screen:

var typed by remember { mutableStateOf("") }
val keyboard = LocalSoftwareKeyboardController.current
val focusManager = LocalFocusManager.current

OutlinedTextField(
    value = typed,
    onValueChange = { typed = it },
    modifier = Modifier.showcase(
        index = 2,
        message = ShowcaseMsg("Type your name to continue"),
        canProceed = typed.isNotBlank(),
        onProceed = {
            focusManager.clearFocus()
            keyboard?.hide()
        }
    )
)

Notes:

  • A step whose canProceed is already true when it is reached behaves like any other step. Only a step that is locked when reached waits for the condition and then advances on its own.
  • The pass-through area is the target's rectangular bounds. With TargetShape.CIRCLE the visible cutout can be a bit larger than that; touches in the extra area are swallowed.
  • next(), previous() and skip() from a custom composable message still work while a step is locked, so you can keep a "Skip" escape hatch. If you don't want a "Next" button to bypass the lock, disable it with enabled = canProceed.
  • onProceed is not tied to locked steps: any step can use it. It fires whatever ends the step: a tap, next()/previous()/skip(), the condition being met, the last step finishing, or a single item being dismissed.
  • Available on both ShowcaseLayout and TargetShowcaseLayout.

ShowcaseMsg

Use ShowcaseMsg() to add a message and customize it with arrow, background and more.

ShowcaseMsg(
    // the message text to be displayed
    "Track your phone usage from here",
    // text style for the message text
    textStyle = TextStyle(color = Color(0xFF827717)),
    // a background color for the text
    msgBackground = MaterialTheme.colors.primary,
    // control corner radius of msgBackground
    roundedCorner = 15.dp,
    // determine if the message will be displayed above or below the target composable
    gravity = Gravity.Bottom,
    // adds an arrow to be displayed with the message
    arrow = Arrow(color = MaterialTheme.colors.primary),
    // starting from version 1.0.3 ShowcaseMsg will have an enter and exit animation of FadeInOut by default you can disable it by using MsgAnimation.None
    enterAnim = MsgAnimation.FadeInOut(),
    exitAnim = MsgAnimation.FadeInOut()
)

Custom composable messages

Starting from version 1.2.0 a message can be any composable instead of text: an image, a card with an icon, a message with buttons, ... Use the trailing-lambda constructor of ShowcaseMsg:

Modifier.showcase(
    index = 2,
    message = ShowcaseMsg(
        gravity = Gravity.Bottom,
        arrow = Arrow(color = Color.White)
    ) {
        Card {
            Column(Modifier.padding(16.dp)) {
                Row {
                    Icon(Icons.Default.Info, contentDescription = null)
                    Text("Tap here to open the menu")
                }
                Row {
                    TextButton(onClick = { previous() }, enabled = hasPrevious) { Text("Back") }
                    TextButton(onClick = { skip() }) { Text("Skip") }
                    Button(onClick = { next() }) { Text("Next") }
                }
            }
        }
    }
)

The same works for the greeting parameter and for showGreeting(ShowcaseMsg { ... }).

  • The composable owns its own look, so text, textStyle and roundedCorner are ignored. msgBackground is ignored by ShowcaseLayout; in TargetShowcaseLayout it still acts as the overlay color of that step.
  • gravity, arrow, enterAnim and exitAnim keep working. The arrow starts from the edge of your composable that faces the target, and if Gravity.Auto has to move the composable to the other side of the target a Side.Top/Side.Bottom arrow points at the edge facing it instead of crossing the target. The composable is always kept on screen.
  • The lambda receives a ShowcaseMsgScope so buttons inside it can drive the showcase: next() advances (or dismisses a single item / greeting), previous() goes back when hasPrevious is true, and skip() ends the whole showcase and calls onFinish. next() is not affected by advanceOnTargetTapOnly or by a locked step.
  • Taps on parts of the composable that are not clickable fall through and advance the showcase exactly like a tap anywhere else. Clickable parts (buttons, cards with onClick, ...) handle their own taps.
  • The content is measured at most as wide as the screen minus a small margin, so prefer wrap-content sizes. Native interop views (e.g. UIKitView) inside the content are not supported.

Arrow

Used with ShowcaseMsg to add an arrow pointing to the target

arrow = Arrow(
    // From where the arrow will point at the target, can be: Top, Bottom, Right or Left
    targetFrom = Side.Top,
    // animates a curved arrow from the message to the target(if true targetFrom is ignored)
    // might not work properly depending on the location of the target on the screen
    curved = true,
    // if false then just draw a line (an arrow without head :P)
    hasHead = false,
    // color of the arrow
    color = MaterialTheme.colors.primary
)
Default Arrow curved = true hasHead = false
Screenshot Screenshot Screenshot

Head style

By default, an Arrow will have a triangle as the head to change this, set head in the arrow to one of these options

TRIANGLE CIRCLE SQUARE ROUND_SQUARE
Screenshot Screenshot Screenshot Screenshot

You can also animate the arrow head and change the size, see the example below.

showcase(
    index = 5, 
    message = ShowcaseMsg(
        "A Circle !",
        textStyle = TextStyle(
            color = Color(0xFF827717),
            fontSize = 18.sp
        ),
        msgBackground = MaterialTheme.colors.primary,
        gravity = Gravity.Top,
        arrow = Arrow(
            color = MaterialTheme.colors.primary,
            targetFrom = Side.Top,
            head = Head.CIRCLE, // head style
            headSize = 30f, // the size of the circle
            animSize = true // animates the arrow head size
        )
    )
)

Logging Events

In recent releases logs have been disabled by default, to print log statement of the current actions taken by compose layout register a listener in your ShowcaseLayout

        registerEventListener(object: ShowcaseEventListener {
            override fun onEvent(level: Level, event: String) {
                println("$level: $event")
            }
        })
