Ich habe eine list_view, die ich testen möchte.Android Espresso listView scrollen zu
list_view Elementlayout ist RelativeLayout
, Adapter ist ItemAdapter
.
Dieser Code in Ordnung (Artikel contatining Daft Punk sichtbar ist) funktioniert:
@Test
public void listViewTest() {
Espresso.onView(withText("Daft Punk")).perform(click());
}
Beide dieser Varianten scheitern:
(das Scrollen beginnt, kommt zu dem Punkt und dann schlägt fehl, ist der Fehler sehr und dieser Frage.)
@Test
public void listViewTest() {
Espresso.onData(artistWithName("Imagine Dragons")).perform(scrollTo(), click());
}
@Test
public void listViewTest() {
Espresso.onData(artistWithName("Imagine Dragons")).
.inAdapterView(withId(R.id.list_view))
.perform(scrollTo(), click());
}
artistWithName Definition:
public static Matcher<Object> artistWithName(String expectedName) {
Checks.checkNotNull(expectedName);
return artistWithName(equalTo(expectedName));
}
public static Matcher<Object> artistWithName(final Matcher<String> itemMatcher) {
Checks.checkNotNull(itemMatcher);
return new BoundedMatcher<Object, ArtistItem>(ArtistItem.class) {
@Override
public void describeTo(org.hamcrest.Description description) {
description.appendText("ArtistTime with name: ");
itemMatcher.describeTo(description);
}
@Override
protected boolean matchesSafely(ArtistItem artistItem) {
return itemMatcher.matches(artistItem.getName());
}
};
}
Fehler:

Was tun, wenn ich auf ein Element einer Listenansicht blättern wollen? (Es ist noch nicht sichtbar) – iskhakovt
Wenn das Element in der Listenansicht ist, wird onData für Sie blättern. Auch wenn es nicht sichtbar ist. So funktioniert es. Wenn es sich um eine ScrollView handelt, müssen Sie scrollTo() verwenden –
