У меня есть GridView, где каждый элемент сетки состоит из ImageView и Checkbox. Теперь, когда я выбираю один флажок, скажем, номер 5, другой флажок, например номер 12, выбирается автоматически. Аналогично для выбора.Флажок, ImageView и GridView
Я не могу понять, почему это происходит. Любая помощь будет оценена.
