    }




//
    private  List<ViewModel> createMockList() {
        List<ViewModel> items = new ArrayList<ViewModel>();
        for (int i = 0; i < 20; i++) {
            items.add(new ViewModel(i, "Item " + (i + 1), URL_FEED + (i % 10 + 1), i + ""));
        }
        return items;

    }


}

I don't know how to import JSON Data to Arraylist. How can I import JSON Array in createMockList() ? Someone help me! I'm beginner. Sorry for my poor english. Thanks You! I want to know how to replace with JSON Array?

You can't just "import" json data, but you can parse it: http://stackoverflow.com/questions/2591098/how-to-parse-json-in-java — Anton Kolyaev, Dec 03 '14 at 08:46
