Espresso: how to scroll to the bottom of ScrollView
Also u can try:
public Matcher<View> getConstraints() {
return allOf(withEffectiveVisibility(ViewMatchers.Visibility.VISIBLE), isDescendantOfA(anyOf(
isAssignableFrom(ScrollView.class), isAssignableFrom(HorizontalScrollView.class), isAssignableFrom(NestedScrollView.class))));
If you have a view inside android.support.v4.widget.NestedScrollView instead of scrollView scrollTo() does not work.
If at the bottom of the ScrollView you need to find a view and match something against it, then simply perform the scrollTo()
action on it, before any other actions that require it to be displayed.
onView(withId(R.id.onBottomOfScrollView))
.perform(scrollTo(), click());
Note: scrollTo will have no effect if the view is already displayed so you can safely use it in cases when the view is displayed
for me when using nestedScrollview i just swipeUp (if you want to go down)..here is an example call:
onView(withId(R.id.nsv_container))
.perform(swipeUp());
For completeness (based on Morozov's answer), you can pass a custom ViewAction
instead of scrollTo()
, which allows to use NestedScrollView
:
ViewAction customScrollTo = new ViewAction() {
@Override
public Matcher<View> getConstraints() {
return allOf(withEffectiveVisibility(ViewMatchers.Visibility.VISIBLE), isDescendantOfA(anyOf(
isAssignableFrom(ScrollView.class),
isAssignableFrom(HorizontalScrollView.class),
isAssignableFrom(NestedScrollView.class)))
);
}
@Override
public String getDescription() {
return null;
}
@Override
public void perform(UiController uiController, View view) {
new ScrollToAction().perform(uiController, view);
}
};
And use it like this:
onView(withId(R.id.onBottomOfScrollView)).perform(customScrollTo, click());
