React Native - ListView

Does the ReactNative ListView accept an array of arrays? I need to get the API data as follows:

[[{"userId":1,"userName":"Ricardo"},{"userId":1,"userName":"Ricardo"}],[{"userId":1,"userName":"Ricardo"},{"userId":1,"userName":"Ricardo"}]].

I made the following code to display it:

renderRowUsers(rowData, sectionID, rowID) {
     return rowData.map(function(user, i){
        return(
          <View key={i}>
            <Text>{user.userId}</Text>
            <View>
              <Text>{user.userName}</Text>
            </View>
          </View>
        );
    });
}

and

const usersDS = new ListView.DataSource({
    rowHasChanged: (r1, r2) => r1.user !== r2.user
});

this.state = {
    usersDataSource: usersDS.cloneWithRows([{
        "userId": "",
        "userName": "Ricardo"
    }])
}

<ListView 
    style={{paddingTop: 2, height:100}}
    dataSource={this.state.usersDataSource}
    renderRow={this.renderRowUsers.bind(this)}
/>

But this returns me the following error:

  

"StaticRender.reder (): A valid React element (or null) must be returned.   have returned undefined, an array or some other invalid object. "
