ExpandableText

Expandable text, similar to Text() in Jetpack Compose.

Sample screen:

Usage

Add the dependency :

implementation 'io.github.dokar3:expandabletext:latest_version'

Show some texts:

val text = "Your long text ".repeat(10)
var expanded by remember { mutableStateOf(false) }
ExpandableText(
    expanded = expanded,
    text = text,
    collapsedMaxLines = 2,
    modifier = Modifier
        .animateContentSize()
        .clickable { expanded = !expanded },
    toggle = { Text(text = if (expanded) "Show less" else "Show more") },
)

Known problems

• toggle will not be visible if:
  • overflow was set to TextOverflow.Ellipsis:

    ExpandableText(
        // ...
        overflow = TextOverflow.Ellipsis,
    )

  • text is an AnnoatedString and a ParagraphStyle was applied to the line needed to show the toggle. For example:

    val text = buildAnnotatedString {
        withStyle(ParagraphStyle()) {
            append("Some long text...")
        }
    }
    ExpandableText(
      text = text,
      // ...
    )
