Я разработал приложение для Android, в котором пользователь мог преобразовать скорость с выбранного пользователем устройства на другие устройства.Как использовать переключатели со списком текстовых просмотров
Интерфейс выглядит следующим образом: 
Когда пользователь вводит значение и выбирает кнопку-переключатель, то 0 с рядом с TextViews должен отображать преобразованные блоки.
Java-код, который я завершил до сих пор выглядит следующим образом:

Однако приложение останавливается, когда я бегу и установите значение в EditText и выберите переключатель.
Любая помощь будет оценена по достоинству.
