Android Espresso : How to match grand parent? without giving exact hierarchy

Issue

onView(allOf(
        withText(activityUnderTest), 
        withParent(withId(R.id.llh_root_record_activity_3_item))))
    .check(matches(anything())) ;

In above code snippet withParent matcher is failing because view id given is not immediate parent but grand parent.

It can be handled as below, but curious to know the trick,specially when you don't want to specify messy hierarchy as used in below code.

onView(allOf(
        withText(activityUnderTest), 
        withParent(withParent(withParent(withId(R.id.llh_root_record_activity_3_item))))))
    .check(matches(anything())) ;

Solution

isDescendantOfA is what you need.
Actually, it doesn't apply to grand parent only. Please check espresso cheat sheet

onView(allOf(withText(activityUnderTest), isDescendantOfA(withId(R.id.llh_root_record_activity_3_item))))
            .check(matches(isDisplayed()));
