onChildView and hasSiblings with Espresso

Question

I am trying to access a button from a specific view. The same view is displayed 6 times. This is the code I am using.

public void testTimeConfig(){
    onData(withDesc("description")).onChildView(withId(R.id.positive)).perform(click());
}

private static Matcher<Object> withDesc(String desc) {
    return allOf(is(instanceOf(String.class)), is(desc));
}

When I run, I get an error:

Error performing 'load adapter data' on view 'is assignable from class: class android.widget.AdapterView'.

Is this the best way to access a child view? If so, how?

EDIT

This is the code I am trying to use now.

   onView(allOf((withContentDescription("description")), hasSibling(withContentDescription("SettingsLayout")), hasSibling(withId(R.id.positive)))).perform(click());

and

   onView(allOf((withContentDescription("description")), hasSibling(withId(R.id.positive)))).perform(click());

With this Error:

   No views in hierarchy found matching

It is the ImageView with id `increaseGoalButton` that I am trying to click.

Is your button inside an item of an AdapterView (e.g. a ListView)? If so, please post the full exception message (it should provide more info on what's wrong). — ValeraZakharov, Dec 31 '13 at 04:58
@ValeraZakharov No it is not. It is just inside a `RelativeLayout` — Chad Bingham, Dec 31 '13 at 05:04
As mentioned below, you should use onView. It'll be much easier to debug if you post the full exception message from logcat (which should include a dump of the view hierarchy). — ValeraZakharov, Jan 02 '14 at 18:45
@ValeraZakharov Is there a way I could send that to you personally? I am under a non-disclosure. — Chad Bingham, Jan 02 '14 at 19:01
@ValeraZakharov and my hierarchy dump exceeds the limit I am able to post on SO. — Chad Bingham, Jan 02 '14 at 19:11

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());

These three examples are all the same – Chad Bingham Dec 31 '13 at 15:26
There are 3 cases: 1st with custom matcher, 2nd for a view with text and 3rd for a view with content description. Does any of them work for you? – denys Dec 31 '13 at 16:04
Sorry, I was looking at them on my phone and all I got was `onView(allOf(withId(R.id.positive)` so they all looked the same. I will play around with this and see if it works – Chad Bingham Dec 31 '13 at 16:18
+1 for mentioning `hasSbiling()`. Do you know if it matters if the view is inside a `RelativeLayout`, inside the parent `RelativeLayout`? So it is two children deep? – Chad Bingham Dec 31 '13 at 17:31
Take a look at source code for `hasSibling()` matcher - [link](https://code.google.com/p/android-test-kit/source/browse/espresso/lib/src/main/java/com/google/android/apps/common/testing/ui/espresso/matcher/ViewMatchers.java#199). Seems that they must be in the same parent. Can you also post your layout xml file, since it's hard to judge without it. – denys Jan 01 '14 at 13:32
Ok I posted the xml. Take a look. Sorry for the delay. I had to edit it so I am not showing sensitive information. – Chad Bingham Jan 02 '14 at 16:58
Is the `com.xxx` needed? – Chad Bingham Jan 02 '14 at 20:32
No, I just took it from your example. You should replace it with your real package name which you changed to com.xxx in above xml code. – denys Jan 02 '14 at 20:37
Right. I am wondering if the com.package is need at all. Right now I am just using `R.id`. without the `com.xx` – Chad Bingham Jan 02 '14 at 20:40
`hasParent` did not work. isDescendantOfA` does. Thanks. – Chad Bingham Jan 02 '14 at 21:50
`hasParent` does not exist. There is a `withParent` method instead. – lacton Sep 23 '14 at 14:04
+1 for `onView(allOf(withId(R.id.increaseGoalButton), isDescendantOfA(withId(R.id.timeGoalWidget)))) .perform(click());` – Ruwanka De Silva Jul 11 '17 at 07:55

None of your content descriptions match the string "description" that's why it doesn't find anything.

Assuming the button id is R.id.positive, and the id is unique in the current activity view, you can simply use:

onView(withId(R.id.positive)).perform(click());
