Android Studio Tutorial – Clipboard (работа с буфером обмена)

[:ru]Андроид обеспечивает clipboard framework (фреймворк буфера обмена) для копирования и вставки различных типов данных. Данные могут быть разных типов: текст, изображения, двоичный поток данных или другие комплексные типы данных.

Android предоставляет библиотеки ClipboardManager, ClipData и ClipData.item фреймворка для копирования и вставки. Для того, чтобы использовать clipboard framework, вы должны поместить данные в объект clip, а затем методом put отправить объект в системный буфер обмена.
