Error performing 'load adapter data'

[automaticqa]

Hello guys, I try to interact with HorizontalGridView's list. All its items contain identical views and strings. so, i try to click on HorizontalGridView's item at first position.

I declared devicesList and ListItem:

object DevicesListScreen : BaseScreen<DevicesListScreen>() {
    val devicesList = KAbsListView(
        builder = {withId(R.id.row_content)},
        itemTypeBuilder = {itemType ( :: ListItem )}
    )

    class ListItem(i: DataInteraction) : KAdapterItem<ListItem>(i) {
        val title = KTextView(i) {
                withDescendant { withId(R.id.deviceType) }
        }
    }
}

I get PerformException: Error performing 'load adapter data' on view '(with id: id/row_content)' If i understsand right I have problem with a ListItem's description/declararion. Could you please advise me, how to declare ListItem correctly in order with its hierarchy using Kakao. Thank you! Спасибо!

Hi there! Actually, the error message tells you that it can't find a list view adapter at a view with id R.id.row_content So it seems there is no adapter in the view espresso matched during runtime. Please make sure that you have your adapter set up before espresso accesses it and that the matcher provided in the builder actually matches your GridView. Cheers!

Thanks! Exactly! Probably it happens because of incorrect ListItem's declaration. That's wht i asked about ListItem

I revised your layout again and I see small issue: you don't need withDescendant declaration if you're matching a text view. Passing parent's data interaction to the KView constructor will limit the matcher to the needed root view of a list item. In the builder, you can directly look for your text view:

    class ListItem(i: DataInteraction) : KAdapterItem<ListItem>(i) {
        val title = KTextView(i) { withId(R.id.deviceType) }
    }
