我需要向下滾動通過我的NestedScrollView爲了測試我的xml文件與Espresso,但我得到錯誤消息:」錯誤執行'滾動到'查看'與ID:「咖啡測試NestedScrollView - 「錯誤執行」滾動到'視圖'與id:「
其他幾個似乎有類似問題的帖子。從這個
我按照說明:Android espresso NestedScrollView, how to scroll to bottom
現在我得到的forementioned錯誤,發現這個帖子:Scrolling to view was attempted, but the view is not displayed
我在NestedScrollView沒有填充 - 我甚至嘗試從XML產品總數去除填充,用於測試目的,但沒有區別。
這是我的測試(到目前爲止,這是不應該做的事情,但向下滾動):
@Test
public void testScrollDownAbilityOfDetailsScrollView(){
goToSpecificItemOnStream(streamItemWithOneImage);
onView(withId(R.id.end_of_details))
.perform(ScrollToAction.betterScrollTo());
}
它使用由滾動自定義要Action類:
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 */)) {
Log.w(TAG, "Scrolling to view was requested, but none of the parents scrolled.");
}
uiController.loopMainThreadUntilIdle();
if (!isDisplayingAtLeast(80).matches(view)) {
throw new PerformException.Builder()
.withActionDescription(this.getDescription())
.withViewDescription(HumanReadables.describe(view))
.withCause(new RuntimeException(
"Scrolling to view was attempted, but the view is not displayed"))
.build();
}
}
public static ViewAction betterScrollTo() {
return ViewActions.actionWithAssertions(new ScrollToAction());
}
@Override
public String getDescription() {
return "scroll to";
}}
定製由於正常的scrollTo方法被硬編碼爲ScrollView和HorizontalScrollView,而不是NestedScrollView,所以有了ScrollToAction類。

我可以告訴我在我的ScrollToAction類的perform方法中遇到了運行時異常,但我還沒有找到解決方法。
在我鏈接的第一篇文章中,新的BetterScrollTo方法似乎像魅力一樣工作。
試這個http://stackoverflow.com/questions/35272953/espresso-scrolling-not-working-when-nestedscrollview-or-recyclerview-is-in-coor –
那是其中一個帖子,我已經遵循。但是,謝謝你:) 它提出了兩件事。首先,你應該創建自己的ScrollToAction類,我已經完成了,還有兩個,即CoordinatorLayout中的NestedScrollView可能會導致問題,但是我的NestedScrollView不在CoordinatorLayout中。 儘管謝謝你的努力! – Silas
編輯: 看過我的NestedScrollView父母后,我發現它實際上是在一個CoordinatorLayout中。雖然它不是CoordinatorLayout的直接子元素,所以在帖子中提到的getParent()方法對我不起作用。 – Silas
