ScrollView

ScrollView is the classic Android scrolling container for one scrolling child.

In the current Droid source pin it is a ViewGroup with a single-child content initializer. You can build a scrolling stack through the hierarchy APIs. Scroll-state callbacks, smooth scrolling, and fillViewport-style controls are not wrapped yet.

Use it when…

Use ScrollView when a short screenful of content may grow taller than the device and should scroll as one block.

Do not put a vertically scrolling list widget inside it; use one scrolling strategy per axis.

How it behaves

ScrollView accepts declarative single-child content and participates in the view hierarchy. Shared view configuration such as onClick(_:), padding, enabled(_:), and visibility(_:) remains available.

The current type does not expose smoothScrollTo(_:_:), fullScroll(_:), arrowScroll(_:), isFillViewport(), or scroll-change listeners at this pin.

Examples

Scroll a settings column

ScrollView(id: 2301) {
    LinearLayout(id: 2302) {
        TextView("Account")
        TextView("Privacy")
        TextView("About")
    }
}

The column becomes scrollable when it is taller than the viewport.

Initializers

ScrollView()
ScrollView(id: 2301)

ScrollView(id: 2301) {
    // single child content via BodyBuilder
}

Layout params

Children use the shared view layout-param surface. The scroll view itself uses frame-style layout params at this pin.

Notes

Smooth-scroll and fill-viewport helpers from Android’s ScrollView are not part of the current Droid API. Place one primary scrolling child and size it through normal layout.
