Android Espresso - 嵌套 parent 的组合 View 匹配器

Question

我想从以下 View 层次结构中找到 ID 为“buttonActionNo”的按钮。

我尝试了下面的代码，但它不起作用。给出“在层次结构中找不到匹配的 View :”错误。

**ViewInteraction appCompatImageButton3 = onView(  
            allOf(withId(R.id.buttonActionNo),   
                        allOf( withhParent(withId(R.id.actionButtonPanel)),

                        allOf( withParent(withId(R.id.outerContainer)),

                        allOf( withParent(withId(R.id.questioContainer)),

                        withParent(withId(R.id.redFlagQuestion1))))),

                        isDisplayed()));

        appCompatImageButton3.perform(click());**

有没有人试图捕获一个嵌套父级很少的 View ？

Answer 1

根据 View 层次结构，您弄错了 outerContainer 和 questioContainer 的顺序。

我会在 onView 中尝试不同的代码示例:

allOf(withId(R.id.buttonActionNo), withParent(withParent(withParent(withParent(withId(R.id.redFlagQuestion1)))))
