I'm using espresso to test an Android application with a recyclerview, and I keep getting this exception.The issue happens when the method,

onView(withId(R.id.playing_recycler)).perform(scrollTo(hasDescendant(withId(R.id.header))));

is called.

The whole Error is here:

android.support.test.espresso.PerformException: Error performing 'scroll RecyclerView to: holder with view: has descendant: with id: com.refactor:id/header' on view 'with id: com.refactor:id/playing_recycler'.

you should override getItemId(int position) and make sure your id is unique

Did you check your keyboard configuration? You should set your keyboard to english and disable swipe

i had this issue and the only way i solved it was to have a custom matcher that could select only one of the views found. your errors shows that multiple views were found with the matcher so espresso cannot make a decision. try this:

public static Matcher<View> withIndex(final Matcher<View> matcher, final int index) {
        return new TypeSafeMatcher<View>() {
            int currentIndex = 0;

            @Override
            public void describeTo(Description description) {
                description.appendText("with index: ");
                description.appendValue(index);
                matcher.describeTo(description);
            }

            @Override
            public boolean matchesSafely(View view) {
                return matcher.matches(view) && currentIndex++ == index;
            }
        };
    }

and then you can call it like this:

 Matcher<View> matcher = allOf(withIndex(withId(R.id.myview),1));
        onView(matcher).perform(click());

special thanks to the author of the matcher. More info here
