using onData in RecyclerView

[GoogleCodeExporter]

What is the recommended way to use onData in a recyclerView ?
It does not seem to be supported. Are than any plans to include support?

Thanks.

RecyclerViewActions only supports performing actions on RecyclerView. 
However it doensn't support check with view assertions the state of a recycler 
view child view.

That WAI. You should use RecylcerViewActions to interact with RV. RV is not 
really compatible with AdapterViews and the way we actually obtain the the View 
for a given piece of data. Here is an example how you should use the API:

    onView(withId(rvLayoutId)).perform(scrollTo(hasDescendant(withText(ITEM_128))));
    onView(withItemText(ITEM_128)).check(matches(isDisplayed()));

So instead of using onData...check(..) you first scroll the View into ViewPort 
using the scrollTo(...) Action and then you can perform a ViewAssertion like 
you usually do with espresso.

Imagine the following layout:

RecyclerView
 -> View 
    -> Other views
    -> Button with text "Ok"
-> View 
    -> Other views
    -> Button with text "Ok"
 -> View 
    -> Other views
    -> Button with text "Ok"
-> View 
    -> Other views
    -> Button with text "Ok"

So I want to assert if the view at index 1 has a button with the text "Ok". 
Using your approach it would be basically an ambiguous query because the same 
text would appear multiple times.

Moreover scrollTo cannot guarantee that the button is actually visible, because 
the child view  of the recycler view could occupy more space than the screen.
