android - onChildView 和 hasSiblings 与 Espresso

Question

我正在尝试从特定 View 访问按钮。同一 View 显示 6 次。这是我正在使用的代码。

public void testTimeConfig(){
    onData(withDesc("description")).onChildView(withId(R.id.positive)).perform(click());
}

private static Matcher<Object> withDesc(String desc) {
    return allOf(is(instanceOf(String.class)), is(desc));
}

当我运行时，出现错误:

Error performing 'load adapter data' on view 'is assignable from class: class android.widget.AdapterView'.

这是访问 subview 的最佳方式吗？如果是，怎么办？

编辑

这是我现在尝试使用的代码。

   onView(allOf((withContentDescription("description")), hasSibling(withContentDescription("SettingsLayout")), hasSibling(withId(R.id.positive)))).perform(click());

和

   onView(allOf((withContentDescription("description")), hasSibling(withId(R.id.positive)))).perform(click());

出现此错误:

我尝试点击的是 ID 为 increaseGoalButton 的 ImageView。

Answer 1

根据您最后的评论，您应该使用 onView() 而不是 onData()。我认为您可以使用 hasSibling() 单击按钮 - example

onView(allOf(withId(R.id.positive), hasSibling(withDesc(someString))))
    .perform(click());

或没有自定义匹配器的示例(同级 View 有文本):

onView(allOf(withId(R.id.positive), hasSibling(withText(someString))))
    .perform(click());

或者(同级 View 有内容描述):

onView(allOf(withId(R.id.positive), hasSibling(withContentDescription(someString))))
    .perform(click());

已编辑:

好的，我会尝试这两种变体:

onView(allOf(withId(R.id.increaseGoalButton), isDescendantOfA(withId(R.id.timeGoalWidget))))
    .perform(click());

或

onView(allOf(withId(R.id.increaseGoalButton), withParent(withId(R.id.timeGoalWidget))))
    .perform(click());
