Espresso CursorAdapter: click on the first item

Question

I can't click on the first item of my Listview backed by a CursorAdapter. Here's what I tried:

onData(is(instanceOf(ContactsListFragment.ContactsAdapter.class)))
    // .inAdapterView(withId(android.R.id.list))
    .atPosition(0)
    .perform(click());

... and here's what I get:
