Based on your last comment you should use onView()
instead of onData()
.
I think you'll be able to click the button using hasSibling()
- example
onView(allOf(withId(R.id.positive), hasSibling(withDesc(someString))))
.perform(click());
or examples without your custom matcher (sibling view has text):
onView(allOf(withId(R.id.positive), hasSibling(withText(someString))))
.perform(click());
or (sibling view has content description):
onView(allOf(withId(R.id.positive), hasSibling(withContentDescription(someString))))
.perform(click());
EDITED:
OK, I'd try these two variants:
onView(allOf(withId(R.id.increaseGoalButton), isDescendantOfA(withId(R.id.timeGoalWidget))))
.perform(click());
or
onView(allOf(withId(R.id.increaseGoalButton), withParent(withId(R.id.timeGoalWidget))))
.perform(click());
