Switch

Switch is the classic Android two-state control for settings that should look immediately on or off.

In the current Droid source pin it is a placeable view control. Shared view interaction and layout APIs work as on any other control; switch-specific checked-state and track/thumb styling are not wrapped yet.

Use it when…

Use a switch for a persistent setting or mode where the on/off meaning should be obvious at a glance, such as enabling notifications or dark theme.

Do not use it when the user is choosing among several exclusive options — that is radio-group territory — or when a compact checkbox fits the form better.

How it behaves

Switch participates in the view hierarchy like other controls. You can assign an id, attach onClick(_:), set padding, and toggle enabled(_:) / visibility(_:).

The current type does not inherit CompoundButton and does not conform to Checkable. Methods such as checked(_:), isChecked(), toggle(), switchMinWidth(_:), trackTintList(_:), and similar Android switch APIs are not available on this Droid type at the current pin.

Examples

Place a settings switch

Switch(id: 2001)
    .padding(h: 16, v: 12)

The control is created and can sit in a settings row like any other view.

React to a tap

let syncSwitch = Switch(id: 2001)

syncSwitch.onClick {
    // Handle the user activating the control.
    // Checked-state reads/writes are not wrapped yet.
}

Disable the control until setup finishes

Switch(id: 2002)
    .enabled(false)

Initializers

Switch()
Switch(id: 2001)

Notes

Android’s full Switch widget has checked state, thumb/track drawables, and text appearance. None of that is part of the current Droid Switch surface. Treat this page as placement plus shared view behavior only.
