Example 6 with Nullable

use of androidx.annotation.Nullable in project butterknife by JakeWharton.

    }
    validateMember(method);
    final boolean propagateReturn = validateReturnType(method, boolean.class);
    final ArgumentTransformer argumentTransformer = createArgumentTransformer(method, ON_ITEM_LONG_CLICK_TYPES);
    List<AdapterView<?>> views = findViews(source, onItemLongClick.value(), isRequired(method), method.getName(), AdapterView.class);
    ViewCollections.set(views, ON_ITEM_LONG_CLICK, (parent, view, position, id) -> {
        Object value = tryInvoke(method, target, argumentTransformer.transform(parent, view, position, id));
        // noinspection SimplifiableConditionalExpression
