是否有可能知道哪个相机目前在Android中使用？

Question

在我的应用程序中，我想知道相机应用程序是否打开以及相机类型（前置摄像头或后置摄像头）？

Answer 1

Camera课程可以解决您的问题。执行getCameraInfo以获取信息，然后使用CameraInfo。它有两个常数：

int CAMERA_FACING_BACK The facing of the camera is opposite to that of the screen.

int CAMERA_FACING_FRONT The facing of the camera is the same as that of the screen.

Answer 2

检查

Camera.CameraInfo.CAMERA_FACING_BACK;

OR

Camera.CameraInfo.CAMERA_FACING_FRONT;
