Почему это сообщение об ошибке происходит со мной? Что мне делать? Я думаю, что это возможно из-за моей двойной переменной веса.
линии 111 в этом методе calculatepaymentbutton.setOnClickListener(new View.OnClickListener()
Интересно, есть ли способ устранить эту проблему double weight = Double.parseDouble(Weight);? Причина того, что я хочу сделать, это то, что когда я нажимаю кнопку calcpayment, я хочу, чтобы моя система проверила, что все заполнено или нет, но когда я нажимаю на эту ошибку, происходит ошибка logcat ~
критическая ошибка: 'Тип ==" document "' –
Таким образом, система не может интерпретировать любое значение в Вес как двойное. Это произойдет, если это значение, например, «sup dog» или «Мне нравится пицца». Самый простой подход - уловить NumberFormatException и обработать его, так как вы допустили бы недопустимый ввод. – Taylor
Тип ввода для 'EditText weighttext' - _numberDecimal_ –
