如何在浓缩咖啡中选择listview？

Question

我正在使用espresso进行测试，在一个页面中有多个AdapterViews，例如，ID:r.id.list1,r.id.list2

public static Matcher<Object> withMainValue(final String value) {
    return new BoundedMatcher<Object,
                            GuessYouLikeGoodItem.DataEntity>(GuessYouLikeGoodItem.DataEntity.class) {
        @Override public void describeTo(Description description) {
            description.appendText("has value " + value);
        }
        @Override public boolean matchesSafely(
                        GuessYouLikeGoodItem.DataEntity item) {
            return item.store_name.contains(value);
        }
    };
}

, 

    android.support.test.espresso.AmbiguousViewMatcherException: 'is assignable from class: class android.widget.AdapterView' matches multiple views in the hierarchy.
    Problem views are marked with '****MATCHES****' below.

如何选择特定的listview并在其上尝试onData？

Answer 1

如果您有多个具有唯一id的listview，您应该能够检查是否显示其中一个列表

onView(withId(R.id.list1)).check(matches(isDisplayed()));

如果您想进入AdapterView内部，这将允许您单击listview内部的元素

onData(anything()).inAdapterView(withId(R.id.list1)).atPosition(0).perform(click());
