摄像头前后摄设定方法,目前有定义值两个分别为CAMERA_FACING_FRONT前置和CAMERA_FACING_BACK后置,摄像头个数int cameraCount = Camera.getNumberOfCameras(); 摄像头个数: int cameraCount = Camera.getNumberOfCameras(); cameraInfo.facing == Camera.CameraInfo.CAMERA_FACING_BACK 后摄 cameraInfo.facing == C...
我们跟踪进去,看下imageSensorFacing 的定义,是在HwCameraInfo结构体里面定义的。 我们再看下ImageSensorFacing都定义了哪些值(如下所示): 好了,跟踪到这一步,那我们接下来就是全局搜索 ImageSensorFacing枚举变量里面的一个值,例如:ImageSensorFacingBack,看下是在哪些地方会用到。 我们看下查找结果里面Camxhwenviron...
