Question

我的应用程序中有几个按钮具有相同的ID，我希望Espresso点击所有这些按钮。这些基本上是折叠/展开按钮，因此我希望UI测试扩展视图中的所有元素。

我总是得到：

android.support.test.espresso.AmbiguousViewMatcherException: 'with id: com.myapp.android:id/liveLinearLayout' matches multiple views in the hierarchy.
Problem views are marked with '****MATCHES****' below.

编辑：根据回复尝试了这个：

onView(allOf(withId(R.id.footage_layout_expand_group))).perform(click());

再次得到这个：

android.support.test.espresso.AmbiguousViewMatcherException: '(with id: com.myapp.android:id/footage_layout_expand_group)' matches multiple views in the hierarchy.
Problem views are marked with '****MATCHES****' below.

Answer 1

如果您知道有多少具有相同ID的项目，您可以使用：

public static Matcher<View> nthChildOf(final Matcher<View> parentMatcher, final int childPosition) {
    return new TypeSafeMatcher<View>() {
        @Override public void describeTo(Description description) {
            description.appendText("with "+childPosition+" child view of type parentMatcher");
        }
        @Override public boolean matchesSafely(View view) {
            if (!(view.getParent() instanceof ViewGroup)) {
                return parentMatcher.matches(view.getParent());
            }
            ViewGroup group = (ViewGroup) view.getParent();
            return parentMatcher.matches(view.getParent()) && group.getChildAt(childPosition).equals(view);
        }
    };
}

对孩子进行getevery并点击它们。然后，使用它：

onView(nthChildOf(withId(R.id.parent_container), itemNumber)
    .perform(click());

在循环中增加itemNumber

Espresso点击具有特定身份
