【问题描述】：

我想从以下视图层次结构中找到 id 为 'buttonActionNo' 的按钮。

我尝试了以下代码，但它不起作用。给出“层次结构中未找到匹配的视图：”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());**

有没有人试图抓住嵌套父母级别很少的视图？

    <LinearLayout
        android:layout_
        android:layout_
        android:orientation="vertical">

        <!-- redFlagQuestion1  -->
        <FrameLayout android:id="@+id/questionOneContainer"

        </FrameLayout>

                layout="@layout/row_base" />


        </FrameLayout>

        <!-- redFlagQuestion 3 -->
        <FrameLayout
            android:layout_

            <include

                layout="@layout/row_base" />

【问题讨论】：

嘿，我对回收器视图适配器上的嵌套父布局有相同的查询。如果您找到任何解决方案，请分享您的宝贵答案提前谢谢您

【参考方案1】：

基于视图层次结构，您错误地按了 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)))))
