Как увеличить камеру с помощью Android CameraX API? ⇐ Android

[Anonymous]

Я пытался увеличить масштаб камеры с помощью приведенного ниже кода с помощью CameraX.

Сначала я получаю предварительный просмотр от CameraX и попытался выполнить масштабирование с помощью предварительного просмотра, как показано ниже.

var config = CameraX.getDefaultUseCaseConfig(PreviewConfig::class.java, lensFacing)
var preview = Preview(config)
preview.zoom(zoom)


После предварительного просмотра.zoom() я просто снова подключаюсь к CameraX и получаю какую-то ошибку, и она не работает.

CameraX.bindToLifecycle(this, preview, imageCapture, videoCapture)


Когда приведенный выше код не работал, я сначала попробовал использовать CameraX.unbindAll(), а затем вызываю CameraX.bindToLifecycle(). Но снова столкнулись с какой-то ошибкой и не смогли добиться успеха в масштабировании.

Дайте мне знать, как мы можем масштабировать камеру с помощью API CameraX. >
