How click in a ImageView whit Autocomplete in Expresso?

Question

I have a Autocomplete box, whit a costum "CityAdapter", how can i access the Button/ImageView using expresso test? I filter the costum adapter by cityName, so i can find the citys by name.

 onView(withId(R.id.autoCompleteCities))
                .perform(typeText(""), closeSoftKeyboard());
         Activity mActivity=mActivityTestRule.getActivity();

onData(instanceOf(CityAdapter.class))
                    .inAdapterView(withId(R.id.autoCompleteCities))
                    .atPosition(0)
                    .onChildView(withId(R.id.tvFavourite))
                    .perform(click());

Here is a example:

You can do the following:

    onView(withId(R.id.autoCompleteCities))
            .perform(typeText("E"));

    onData(instanceOf(City.class))
            .inRoot(RootMatchers.isPlatformPopup())
            .atPosition(0)
            .onChildView(withId(R.id.tvFavourite))
            .perform(click());

onView(~).perform(~) is to show the auto complete listview in the view-port.
onData(instanceOf(City.class)) This will find the view with the object same as that of the mentioned class (here City.class).
inRoot(RootMatchers.isPlatformPopup()) The dropdown menu is on another window than the default window your activity runs in. So we have to specify that we want to search that window.
atPosition(0) Selects the item at the specified position in the array-list or list-view.
onChildView(withId(R.id.tvFavourite)) Selects the child view with the specified ID (here image-view).
