#鸿蒙通关秘籍#使用 cameraPicker 调用系统相机进行拍照，取消拍摄事件如何监听？

可以通过cameraManager设置状态回调返回相机状态。

import { camera } from '@kit.CameraKit'; 
import { BusinessError } from '@kit.BasicServicesKit'; 

let cameraManager = camera.getCameraManager(getContext(this)); 
cameraManager.on('cameraStatus', (err: BusinessError, cameraStatusInfo: camera.CameraStatusInfo) => { 
    console.log(`camera : ${cameraStatusInfo.camera.cameraId}`); 
    console.log(`status: ${cameraStatusInfo.status}`); 
});
