Android系统.浓咖啡.如何点击带文字的微调项目？

我正在尝试编写测试,按文本执行单击旋转器项目.

我的测试包含以下几行:

onView(withId(R.id.spn_trans_type)).perform(click());
onData(anything()).inAdapterView(withId(R.id.spn_trans_type)).onChildView(allOf(withId(textViewIdToTest), withText(expectedText))).perform(click());

但有例外: NoMatchingViewException: No views in hierarchy found matching: with id: com.rirdev.aalf.demo:id/spn_trans_type

我的问题是:如何找到微调器适配器视图？换句话说,我应该在adapterView()方法中添加什么？

我已经找到了这个答案:

替换withText()为withSpinnerText()

onView(withId(spinnerId)).perform(click());
onData(allOf(is(instanceOf(String.class)), is(selectionText))).perform(click());
onView(withId(spinnerId)).check(matches(withSpinnerText(containsString(selectionText))));

来自: Android Espresso检查选定的微调文本

onData(anything())
    .inAdapterView(withId(R.id.spn_trans_type))
    .onChildView(allOf(withId(textViewIdToTest), withText(expectedText)))
    .perform(click());

onData(allOf(is(instanceOf(String.class)), is(selectionText)))
    .perform(click());
onView(withId(spinnerId))
    .check(matches(withSpinnerText(containsString(selectionText))));
