You should use a Custom ViewAction:

public void clickOnImageViewAtRow(int position) {
    onView(withId(R.id.recycler_view)).perform(RecyclerViewActions.actionOnItemAtPosition(position, new ClickOnImageView()));
}

public class ClickOnImageView implements ViewAction{
    ViewAction click = click();

    @Override
    public Matcher getConstraints() {
        return click.getConstraints();
    }

    @Override
    public String getDescription() {
        return " click on custom image view";
    }

    @Override
    public void perform(UiController uiController, View view) {
        click.perform(uiController, view.findViewById(R.id.imageView));
    }
}
