CollapsibleActionView

interface CollapsibleActionView(source)

Deprecated

Use the platform-provided android.view.CollapsibleActionView interface.

When a android.view.View implements this interface it will receive callbacks when expanded or collapsed as an action view alongside the optional, app-specified callbacks to androidx.core.view.MenuItemCompat.OnActionExpandListener.

See androidx.core.view.MenuItemCompat for more information about action views. See android.app.ActionBar for more information about the action bar.
