Using Espresso to click view inside RecyclerView item

How can I use Espresso to click a specific view inside a RecyclerView item? I know I can click the item at position 0 using:

onView(withId(R.id.recyclerView))
.perform(RecyclerViewActions.actionOnItemAtPosition(0, click()));


But I need to click on a specific view inside that item and not on the item itself.

Thanks in advance.

-- edit --

To be more precise: I have a RecyclerView (
R.id.recycler_view
) which items are CardView (
R.id.card_view
). Inside each CardView I have four buttons (amongst other things) and I want to click on a specific button (
R.id.bt_deliver
).

I would like to use the new features of Espresso 2.0, but I'm not sure that is possible.

If not possible, I wanna use something like this (using Thomas Keller code):

onRecyclerItemView(R.id.card_view, ???, withId(R.id.bt_deliver)).perform(click());


but I don't know what to put on the question marks.

Answer

You can do it with customize view action.

public class MyViewAction {

    public static ViewAction clickChildViewWithId(final int id) {
        return new ViewAction() {
            @Override
            public Matcher<View> getConstraints() {
                return null;
            }

            @Override
            public String getDescription() {
                return "Click on a child view with specified id.";
            }

            @Override
            public void perform(UiController uiController, View view) {
                View v = view.findViewById(id);
                v.performClick();
            }
        };
    }

}

Then you can click it with

onView(withId(R.id.rv_conference_list)).perform(
            RecyclerViewActions.actionOnItemAtPosition(0, MyViewAction.clickChildViewWithId(R.id. bt_deliver)));
