嵌套式RecyclerView的Espresso Matcher [英] Espresso Matcher for Nested RecyclerView

问题描述

这是我的层次结构的细分:

So here's a breakdown of my hierarchy:

RecyclerView --> LinearLayout --> RecyclerView --> FrameLayout -> FrameLayout 

以下是屏幕截图:

我希望能够验证显示文本的 FrameLayout .这是我到目前为止尝试过的:

I would like to be able to verify the FrameLayout with the text is displayed. This what I have tried so far:

onView(withRecyclerView(R.id.container_list).atPositionOnView(0, R.id.row_content))
                .check(matches(withRecyclerView(R.id.row_content).atPositionOnView(0, R.id.info_field)))
                .check(matches(isDisplayed()));

但是它会导致 AmbiguousViewMatcherException .关于如何验证该嵌套视图的任何想法?应该提到我正在使用

But it causes an AmbiguousViewMatcherException. Any ideas on how to verify that nested view? Should mention I'm using the ViewMatcher from here. Thanks.

推荐答案

我可以使用上面提供的@manidesto解释进行一些细微的更改来验证它.

I was able to verify it using the explanation @manidesto provided above with some slight changes.

onView(allOf(isDescendantOfA(withRecyclerView(R.id.container_list).atPosition(0)),
                isDescendantOfA(withRecyclerView(R.id.row_content).atPosition(0)),
                withId(R.id.info_field)))
                .check(matches(isDisplayed()));

主要增强之处是我使用 allOf 匹配器指定了我要验证的视图的多个特征.

Main enhancement is I used the allOf matcher to specify multiple characteristics of the view I was trying to verify.
