Use this to iterate through a recycler view item and check each position to see if a view exists that has some specific text set

MatchChildViewWithText.kt

        fun matchChildViewOfAccountTile(accountName: String, targetViewId: Int, itemMatcher: Matcher<View>): Matcher<View> =
            object : BoundedMatcher<View, RecyclerView>(RecyclerView::class.java) {
                override fun describeTo(description: Description) {
                    description.appendText("Has view id $targetViewId and matches $itemMatcher for item with name $accountName")
                }

                public override fun matchesSafely(recyclerView: RecyclerView): Boolean {
                    val itemCount = recyclerView.adapter.itemCount
                    for (i in 0 until itemCount) {
                        val holder = recyclerView.findViewHolderForAdapterPosition(i)
                        if (holder != null) {
                            val accountNameView = holder.itemView.findViewById<View>(R.id.accountTileAccountName) as TextView
                            if (accountNameView.text == accountName) {
                                val targetView = holder.itemView.findViewById<View>(targetViewId)
                                return itemMatcher.matches(targetView)
                            }
                        }
                    }
                    return false
                }
            }

it's really perfect
