Я разработал пользовательскую клавиатуру, указанную для букв, используемых в черкесском языке.Проблема в том, что я не могу изменить тему (внешний вид) клавиатуры относительно выбранной пользователем темы.Я предоставил пользовательский интерфейс, чтобы пользователи могли выбирать темы по своему выбору.После нажатия на метод выбора темы InputMethodService останавливается и запускается.Но клавиатура остается прежней.
Я создал файлы макетов для каждой темы, которую я хотел бы добавить, и я использую их для создания экземпляра KeyboardView в методе onCreateInputView метода InputMethodService.Ниже приведен код для InputMethodService.
