У меня есть приложение для камеры в Android

Question

У меня есть приложение для камеры в Android. Существует изображение и две кнопки. Когда я нахожусь в ландшафтном режиме, две кнопки будут доступны на изображении и когда я буду в режиме портрета, кнопки будут скрыты, а соотношение сторон будет правильным.

Answer 1

создавать различные макеты для портретной и альбомной так:

и измените видимость кнопки в другом макете, используя это: android: visibility = "invisible" Ваша проблема, несомненно, будет решена.
