Я попытался увеличить камеру с помощью приведенного ниже кода, используя CameraX
.
Сначала я получил Preview
от CameraX
и попытался выполнить масштабирование, используя Preview
, как показано ниже.
var config = CameraX.getDefaultUseCaseConfig(PreviewConfig::class.java, lensFacing)
var preview = Preview(config)
preview.zoom(zoom)
После preview.zoom()
Я просто снова связываюсь с CameraX
и получаю какую-то ошибку, и она не работает.
CameraX.bindToLifecycle(this, preview, imageCapture, videoCapture)
Когда приведенный выше код не работал, я сначала попытался с помощью CameraX.unbindAll()
, а затем позвонил CameraX.bindToLifecycle()
. Но снова столкнитесь с некоторой ошибкой и не добьетесь успеха в увеличении.
Дайте мне знать, как мы можем увеличить камеру, используя CameraX
API.
Обновление журнала ошибок ниже:
Журнал ошибок с использованием только CameraX.bindToLifecycle()
:
java.lang.IllegalArgumentException: Exceeded max simultaneously bound image capture use cases.
