我有一个自定义适配器，如MyCustomAdapter，它扩展了BaseAdapter。 我还有一个listView，我添加了一个footerView：
protected ListView mItemsList;
// Adapter
protected myCustomAdapter mAdapter;
@VisibleForTesting
public static final String FOOTER = "FOOTER";
View footerView = LayoutInflater.from(this).inflate(R.layout.footer_view, mItemsList, false);
mItemsList.addFooterView(footerView, FOOTER, true);
现在我想找到页脚并用Espresso进行测试。这是我正在使用的代码：
public void testClickFooter() {
onData(isFooter()).perform(click());
}
private Matcher<Object> isFooter() {
// This depends on Activity.FOOTER being passed as data in the addFooterView method.
return allOf(is(instanceOf(String.class)), is(ChecklistBaseActivity.FOOTER));
}
失败，我收到以下错误：
com.google.android.apps.common.testing.ui.espresso.AmbiguousViewMatcherException: 'is assignable from class: class android.widget.AdapterView' matches multiple views in the hierarchy.
Problem views are marked with '****MATCHES****' below.

为什么会发生，解决方案是什么？
答案 0 :(得分：0)
如错误显示问题视图标有'**** MATCHES ****'，如果您按照错误在ListView前面找到'**** MATCHES ***'，在层次结构中找到Spinner
为了解决您有多个适配器视图的问题，您可以调用ViewMatchers.inAdapterView()：
onData(isFooter()).inAdapterView(withId(R.id.list)).perform(click());
你已经完成了。
