android espresso : total count of elements with samerid not in adapter view

问题

I am trying to get the count of elements with same rid

The solutions here How to get count of items with same ids which are not in adapter view is not helping me.

 static int counter = 0;
public static Matcher<View> withIdAndDisplayed(final int id) {
    Checks.checkNotNull(id);
    return new TypeSafeMatcher<View>() {
        @Override
        public void describeTo(Description description) {
            description.appendText("with item id: " + id);
        }

        @Override
        public boolean matchesSafely(View view) {
            if ((view.getId() == id) && (view.getGlobalVisibleRect(new Rect())
                    && withEffectiveVisibility(ViewMatchers.Visibility.VISIBLE).matches(view))){
                counter++;
                return true;
            }
            return false;
        }
    };
}

Update:

I see you trying to get child view count which is not an adapterView. See this one https://groups.google.com/forum/#!topic/android-test-kit-discuss/avLaBnBWr70

Original answer:

Are you using RecyclerView?

I used below code in my tests to get the RecyclerView size.

 public static Matcher<View> withRecyclerViewSize(final int size) {
    return new TypeSafeMatcher<View>() {

        @Override
        public boolean matchesSafely(final View view) {
            final int actualListSize = ((RecyclerView) view).getAdapter().getItemCount();
            LOGD(TAG, "RecyclerView actual size " + actualListSize);
            return actualListSize == size;
        }

        @Override
        public void describeTo(final Description description) {
            description.appendText("RecyclerView should have " + size + " items");
        }
    };
}

Usage: onView(withId(R.id.resource_id)).check(matches(withRecyclerViewSize(expectedSize)));

In this case resource_id is RecyclerView.

There are few examples here: https://gist.github.com/chemouna/00b10369eb1d5b00401b.
