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());
