RecyclerViewActions returns NoMatchingViewException in Espresso Android Testing

问题

I'm using this line of code to perform a click on RecyclerView's list at position 0.

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

But it's not working and returns NoMatchingViewException.

But, when I perform a click operation on TextView (which is inside the RecyclerView layout), it's working and testing is passing, as shown in the line of code below,

    onView(allOf(result(withId(R.id.tv), 0), isDisplayed())).perform(click());

Am I using the RecyclerViewActions correctly, and how do I resolve the issue?
