RadioButton

RadioButton is one option in a mutually exclusive choice.

In the current Droid source pin it is a placeable view control. Shared view interaction and layout APIs work; checked state, button tint, and group coordination are not wrapped on this type.

Use it when…

Use a radio button when the choice is one-of-many and the user should see the classic Android radio affordance.

For independent on/off options, see CheckBox. For group selection APIs, see RadioGroup.

How it behaves

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

At this pin RadioButton inherits View only. It does not inherit CompoundButton and does not conform to Checkable. Methods such as checked(_:), isChecked(), toggle(), buttonTintList(_:), and buttonDrawable(_:) are not available on RadioButton.

Examples

Place one option

RadioButton(id: 5001)
    .padding(h: 16, v: 12)

React to a tap

let option = RadioButton(id: 5002)

option.onClick {
    // Handle activation. Checked-state reads/writes are not wrapped yet.
}

Initializers

RadioButton()
RadioButton(id: 5001)

Notes

Android’s RadioButton is a CompoundButton. The current Droid type is not. Use CompoundButton when you need the verified Checkable methods (checked(_:), isChecked(), toggle()), and RadioGroup for group-level check(_:) / clearCheck() / checkedRadioButtonId().
