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.

Solution 1

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());

Solution 2

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

[Chad Bingham]

These three examples are all the same

[denys]

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?

[Chad Bingham]

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]

+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?

[denys]

Take a look at source code for hasSibling() matcher - link. 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.

[Chad Bingham]

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]

Is the com.xxx needed?

[denys]

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.

[Chad Bingham]

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]

hasParent did not work. isDescendantOfA` does. Thanks.

[lacton]

hasParent does not exist. There is a withParent method instead.

[Ruwanka Madhushan]

+1 for onView(allOf(withId(R.id.increaseGoalButton), isDescendantOfA(withId(R.id.timeGoalWidget)))) .perform(click());
