CameraViewfinder.ImplementationMode
enum CameraViewfinder.ImplementationMode
The implementation mode of a CameraViewfinder.
User preference on how the CameraViewfinder should render the viewfinder. CameraViewfinder displays the viewfinder with either a SurfaceView or a TextureView. A SurfaceView is generally better than a TextureView when it comes to certain key metrics, including power and latency. On the other hand, TextureView is better supported by a wider range of devices. The option is used by CameraViewfinder to decide what is the best internal implementation given the device capabilities and user configurations.

Enum Values
COMPATIBLE
val CameraViewfinder.ImplementationMode.COMPATIBLE: CameraViewfinder.ImplementationMode
Use a TextureView for the viewfinder.
PERFORMANCE
val CameraViewfinder.ImplementationMode.PERFORMANCE: CameraViewfinder.ImplementationMode
Use a SurfaceView for the viewfinder when possible. A SurfaceView has somewhat lower latency and less performance and power overhead than a TextureView. Use this If the device doesn't support SurfaceView, CameraViewfinder will fall back to use a TextureView instead.
CameraViewfinder falls back to TextureView when the API level is 24 or lower, the camera hardware support level is INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY.
Public functions
valueOf
java-static fun valueOf(name: String!): CameraViewfinder.ImplementationMode!
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
| Returns | |
|---|---|
CameraViewfinder.ImplementationMode! |

| Throws | |
|---|---|
java.lang.IllegalArgumentException |
if this enum type has no constant with the specified name |
values
java-static fun values(): Array<CameraViewfinder.ImplementationMode!>!
Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants.
