How implement item list click listener? I create list on widgets like codelabs(MOKO Widgets #7 - lists on widgets), all works, but i dont understand how add listener from item click.

My code: My ViewModel:

UnitItem:

You should to add clickable widget to the ServerUnitItem to handle clicks. And pass a callback to constructor of the unit class:

class ServerUnitItem(
    // ...
    private val clickListener: (ServerModel) -> Unit
) : WidgetsTableUnitItem<ServerModel>(itemId, server) {

    // ...

    override fun createWidget(data: LiveData<ServerModel>): UnitItemRoot {
        return with(theme) {
            clickable( // Wrap some widget into clickable widget
                onClick = { // Add onClick action
                    clickListener(data.value)
                },
                child = constraint(size = WidgetSize.WidthAsParentHeightWrapContent) {
                    // ...
                }
            ).let { UnitItemRoot.from(it) }
        }
    }
}

And then in the function of unit creation in the screen class you can handle clicks:

fun serversToTableUnits(servers: List<ServerModel>, viewModel: ServerViewModel): List<TableUnitItem> {
    return servers.map { server ->
        ServerUnitItem(
            // ...
            clickListener = { // here you can handle click to an unit
                viewModel.onClickToItem(it)
            }
        )
    }
}
