I have a heterogeneous recycler view and I am trying to scroll it to item at position 30. My test is passing but I cannot see the screen actually scrolling.

onView(withId(R.id.content_view))
    .perform(RecyclerViewActions.scrollToPosition(30));

This is what I am doing to scroll.

Use scrollToHolder():

onView(withId(R.id.recyclerViewId))
    .perform(scrollToHolder(viewHolderMatcher(some_parameter_to_match)));

where viewHolderMatcher(some_parameter_to_match) returns Matcher<RecyclerView.ViewHolder> i.e. the position of the holder/item in the RecyclerView.

Or only by position:

onView(withId(rvLayoutId))
    .perform(actionOnItemAtPosition(256, scrollTo()));

last one is from here.
