Android - Textview исчезает при операции перетаскивания

Я создаю одно приложение для редактирования изображений. В котором я даю возможность открыть камеру или галерею, чтобы выбрать картинку. При выборе картинки пользователь перейдет на другую страницу. На другой странице, чтобы показать картинку, я использую один вид, который реализует AppCompactImageView. Теперь я даю возможность добавить текст, используя edittext. При нажатии кнопки «Готово» на программной клавиатуре текст редактирования исчезнет и будет заменен на TextView. Теперь я хочу перетащить этот TextView по всему макету. Но после операции сбрасывания она исчезает. Ниже мой код. Любая помощь будет ощутимой.
