Из журнала ошибок: проблема в рисовании для ImageView.Убедитесь, что он существует в папке drawable.Может быть, вы сохранили его в подпапке, например drawable-v21, поэтому его невозможно найти.

Кажется, @drawable/bot в вашем ImageView не может быть найден.Попробуйте заменить его.Убедитесь, что имя файла, которое можно нарисовать, не использует тире

  • file-name.xml - плохо
  • file_name.xml - хорошо
