Please try out the following solution. It might work for you. The core idea is considering using custom ViewMatcher for your case.

public static Matcher<View> withItalicStyle(final int resourceId) {
    return new TypeSafeMatcher<View>() {
        @Override
        public void describeTo(Description description) {
            description.appendText("has Italic Text with resource" );
        }

        @Override
        public boolean matchesSafely(View view) {
            TextView textView = (TextView) view.findViewById(resourceId);
            return (textView.getTypeface().getStyle() == Typeface.ITALIC);
        }
    };
}

And in you testcase, you can

    onView(CustomMatchers.withItalicStyle(R.id.yourResourceId)).check(isDisplayed());
