У меня есть встроенное приложение, которое получает сообщение с сервера, сохраняет его в текстовый файл и отображает текстовый файл на экране.Тем не менее, текст всегда превышает виджет ScrollView и идет на некоторые другие виджеты, как на рисунке ниже.
Есть ли способы решить эту проблему?Любая помощь будет оценена.Спасибо.
Это мой код:
#Todo: fix line 334 AttributeError
#Remove the upload button also
#Error Fixed
#Todo: fix message received exceeds border error
