Я создаю собственное приложение для загрузки контактов телефонной книги в мое приложение, используя эту библиотеку. Я правильно загрузил контакты в свое приложение. Теперь я хотел загрузить эти контактные данные в раскрывающемся списке. Я использовал response-native-множественный выбор, чтобы загрузить контакт, используя эту библиотеку. Но я не могу загрузить контакт в эту библиотеку.
Интерфейс, который мне нужен для загрузки контактных данных.
Это то, что я пробовал,
