我试图在我的表单中测试NestedScrollView中的EditTexts.我正在运行以下代码:

onView(withId(R.id.register_scroll_view)).perform(scrollTo()).perform(click());

其中register_scroll_view是我的NestedScrollView.但是,我得到一个例外:

android.support.test.espresso.PerformException:在视图'上执行'滚动到'时出错,ID为:com.eazyigz.myapp:id/register_scroll_view'.引起:java.lang.RuntimeException:不会执行Action,因为目标视图不匹配以下一个或多个约束:(视图具有有效可见性= VISIBLE并且是a的后代:(可从类中分配:class android .widget.ScrollView或可从类中分配:class android.widget.Horizo​​ntalScrollView))

如何正确设计此测试,以便我可以测试需要滚动到可见的EditTexts？

我需要向下滚动浏览我的NestedScrollView以使用Espresso测试我的xml文件,但是我收到错误消息:"在视图上执行'滚动到'时出错",ID为:

其他几个帖子似乎也有类似的问题.

我遵循了以下说明:Android espresso NestedScrollView,如何滚动到底部

现在我得到前面提到的错误,并发现这篇文章:尝试滚动查看,但不显示视图

我的NestedScrollView中没有填充 - 我甚至尝试从XML中删除填充,用于测试目的,但它没有任何区别.

这是我的测试(到目前为止它不应该做任何事情,但向下滚动):

    @Test
    public void testScrollDownAbilityOfDetailsScrollView(){
        goToSpecificItemOnStream(streamItemWithOneImage);

        onView(withId(R.id.end_of_details))
                .perform(ScrollToAction.betterScrollTo());

    }

它使用自定义的Scroll To Action类:

    public final class ScrollToAction implements ViewAction {

    private static final String TAG = ScrollToAction.class.getSimpleName();

    @SuppressWarnings("unchecked")
    @Override
    public Matcher<View> getConstraints() {
        return allOf(withEffectiveVisibility(Visibility.VISIBLE), isDescendantOfA(anyOf(
                isAssignableFrom(ScrollView.class),    isAssignableFrom(HorizontalScrollView.class), isAssignableFrom(NestedScrollView.class))));
    }

    @Override
    public void perform(UiController uiController, View view) {
        if (isDisplayingAtLeast(80).matches(view)) {
            Log.i(TAG, "View is already displayed. Returning.");
            return;
        }
        Rect rect = new Rect();
        view.getDrawingRect(rect);
        if (!view.requestRectangleOnScreen(rect, true /* immediate …

使用Espresso我尝试滚动到linearlayout内的textview - 但是我得到了这个例外:
