Is it possible to add a way to change the root of the DataMatcher?

[Scrubles]

I'm trying to select a item on the dropdown of an AutoCompleteTextView. First I tried with the UiAutomator2, but there was nothing available there to make it work, then I tried with this library, but I stopped at the same point. I made it work running Espresso directly on my app, but I needed to use the method inRoot(isPlatformPopup()), which isn't available here, is it possible to add a way to call it?

I tried to call the inAdapterView, but I think it's 2 different things, and it didn't work.

Maybe https://developer.android.com/reference/androidx/test/espresso/matcher/RootMatchers ?
Then I think currently this driver does not have it yet.

Do you if there's any other way to find elements on popups?

[mykola-mokhnach]

Have you tried to use -android viewmatcher locators?

[KazuCocoa]

First I tried with the UiAutomator2, but there was nothing available there to make it work

so, potentially this does not help, but you could use the below in an espresso session:
https://github.com/appium/appium-espresso-driver#mobile-uiautomator
https://github.com/appium/appium-espresso-driver#mobile-uiautomatorpagesource

[mykola-mokhnach]

After v2.11.0 is is possible to provide root matchers to -android viewmatcher locators. See #822

I don't know if I should reopen this issue or create a new one.
Using the root matcher, I was able to find the element, but when I try to click on it, I receive this Exception.

I think it's trying to find element in the old scope.

Is it possible to add the scope to the DataMatcher as well?

Also, I think there is an error on ViewFinder.kt line 184:

getViews(root, matcherJson.query.matcher as Matcher<View>, findOne, matcherJson.query.scope as Matcher<Root>)

The scope should be Matcher? to allow nullable, shouldn't it?

[mykola-mokhnach]

Could you provide the full stack trace?

[mykola-mokhnach]

Also feel free to provide fixes - I don't have a possibility to test changes with a real app

[Scrubles]

That's all I have, how do I get the full stacktrace?

[mykola-mokhnach]

#824 should (probably) do the job

[mykola-mokhnach]

#825 should enable scope argument support for data matchers

[mykola-mokhnach]

Both PRs were published in driver version 2.12.0

[mykola-mokhnach]

basically setting the scope locator value is equal to providing inRoot matcher. If it is necessary to provide the parent AdapterView (e.g. the current page contains multiple ones) then find it first and use as context for the data matcher lookup (e.g. findElement(adapter view locator).findElement(data matcher))
