Use Jetpack Compose vertically scrollable component in ConstraintLayout

Question

I have a player layer with subtitle layer like this:

Parent of player layer is and XML ConstraintLayout that have a ComposeView child. This ComposeView is my subtitle layer.

<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#000000">

    <com.google.android.exoplayer2.ui.PlayerView
        android:id="@+id/video_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:animateLayoutChanges="true"
        app:auto_show="true"
        app:controller_layout_id="@layout/layout_exoplayer_control_views"
        app:surface_type="surface_view"
        app:use_controller="true" />

    <androidx.compose.ui.platform.ComposeView
        android:id="@+id/subtitle_layout"
        android:layout_width="250dp"
        android:layout_height="match_parent"
        android:background="@color/black_50"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

In subtitle layer I have a Column that I want to add Modifier.verticalScroll(rememberScrollState()) for scroll to bottom content such as LazyColumn subtitle list and more.

@Composable
fun SubtitleScreen(
    newSubtitleList: List<PlayerTrackModel>, viewModel: PlayerViewModel
) {

    var items by remember { mutableStateOf(newSubtitleList) }

    Column(
        modifier = Modifier
            .fillMaxWidth()
            .background(Color.Black)
            .padding(6.dp)
            .verticalScroll(rememberScrollState())
    ) {
        ...
    }
}

When I do this, I get java.lang.IllegalStateException . This is full log:

java.lang.IllegalStateException: Vertically scrollable component was measured with an infinity maximum height constraints, which is disallowed. One of the common reasons is nesting layouts like LazyColumn and Column(Modifier.verticalScroll()). If you want to add a header before the list of items please add a header as a separate item() before the main items() inside the LazyColumn scope. There are could be other reasons for this to happen: your ComposeView was added into a LinearLayout with some weight, you applied Modifier.wrapContentSize(unbounded = true) or wrote a custom layout. Please try to remove the source of infinite constraints in the hierarchy above the scrolling container.

How can solve this issue?

Answer 1

I figure out that the LazyColumn I used in Column parent with Modifier.verticalScroll(rememberScrollState()) is the source of crash.

As a Google I/O talk, you shouldn't use nesting components scrollable in the same direction. For more info on why and what is the solution, check out this talk .
