setTitleOptionalHint

open fun setTitleOptionalHint(titleOptional: Boolean): Unit

Set whether or not the title/subtitle display for this action mode is optional.

In many cases the supplied title for an action mode is merely meant to add context and is not strictly required for the action mode to be useful. If the title is optional, the system may choose to hide the title entirely rather than truncate it due to a lack of available space.

Note that this is merely a hint; the underlying implementation may choose to ignore this setting under some circumstances.

Parameters
titleOptional Boolean: true if the title only presents optional information.
