bindCameraUseCases()的回调

Question

我正在尝试获得一个android camerax_version = '1.0.0-beta03‘示例，遵循官方的camerax示例。要启动预览，将调用viewFinder.post {bindCameraUseCases()}。当bindCameraUseCases()内部的bindToLifecycle完成时，有可能得到一个回调吗？

因此，在侯赛因·哈基姆的暗示下，我终于得到了我想要的：

        Camera2Interop.Extender(builder).setSessionStateCallback(object: CameraCaptureSession.StateCallback() {
        override fun onConfigureFailed(session: CameraCaptureSession) {}

        override fun onConfigured(session: CameraCaptureSession) {}

        override fun onActive(session: CameraCaptureSession) {
            Log.d("CameraX", "First Frame")
        }
        override fun onClosed(session: CameraCaptureSession) {
            Log.d("CameraX", "Last Frame")
        }
    })
