Espresso. Error performing 'load adapter data'

Question

I have a ListView, which shows data from a database. ``` db = new DB(this); db.open(); String[] from = new String[]{DB.COLUMN_FIRSTNAME, DB.COLUMN_LASTNAME}; int[] to = new int[]{android.R.id.text1, android.R.id.text2}; scAdapter = new SimpleCursorAdapter(this, android.R.layout.simple_list_item_activated_2, null, from, to, 0); lvData = (ListView) findViewById(R.id.lvData); lvData.setAdapter(scAdapter); lvData.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL); lvData.setMultiChoiceModeListener(new AbsListView.MultiChoiceModeListener() { ``` It shows the first name and last name from the database as a list of items: Click to UI So, today I tried to use Espresso with this app and I can't find a way to click on the item containing the text.

```
onData(withRowString(DB.COLUMN_FIRSTNAME, "Ivan")).perform(click());
```
