Я работаю над JSON.I проанализировал JSON, и я могу показать свой JSON listview (изображения и тексты), а также я успешно создал виджет, и я хочу показать заголовок первого предмета JSON в мой widget.i также написал этот код (если я опускаю виджет, то могу показать первый заголовок в виджетах), но виджет не обновляется. Первый элемент JSON обновлен, но заголовок виджета не обновляется. Что не так? если кто-нибудь знает решение, пожалуйста, помогите мне спасибо Это мой код:Android-виджет не обновляется автоматически
