GuidedAction

open class GuidedAction : Action
kotlin.Any
   ↳ androidx.leanback.widget.Action
   ↳ androidx.leanback.widget.GuidedAction

A data class which represents an action within a . GuidedActions contain at minimum a title and a description, and typically also an icon.

A GuidedAction typically represents a single action a user may take, but may also represent a possible choice out of a group of mutually exclusive choices (similar to radio buttons), or an information-only label (in which case the item cannot be clicked).

GuidedActions may optionally be checked. They may also indicate that they will request further user input on selection, in which case they will be displayed with a chevron indicator.

GuidedAction recommends to use Builder. When application subclass GuidedAction, it can subclass BuilderBase, implement its own builder() method where it should call BuilderBase#applyValues(GuidedAction).
