用picker去new PhotoViewPicker()对象可以实现，photoAccessHelper主要用作选择图片

参考：

https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-file-picker

相关代码参考：

import { photoAccessHelper } from '@kit.MediaLibraryKit';  
import { BusinessError } from '@kit.BasicServicesKit';  
import { hilog } from '@kit.PerformanceAnalysisKit';  
import picker from '@ohos.file.picker';  
  
@Entry  
@Component  
struct PhotoPickerPage2 {  
  @State img: string = ''  
  
  aboutToDisappear() {  
  }  
  
  build() {  
    Column() {  
      Button("Button")  
        .onClick(() => {  
          let photoPicker = new picker.PhotoViewPicker();  
          photoPicker.select(  
            {MIMEType: 'image/*', maxSelectNumber: 1, isPhotoTakingSupported: true, isEditSupported: true, isSearchSupported: false} as photoAccessHelper.PhotoSelectOptions  
          ).then((res) => {  
            if (res.photoUris.length > 0) {  
              this.img = res.photoUris[0]  
            }  
          }).catch((err: BusinessError) => {  
            hilog.info(1, "hilog",'select error: ' + err.code + ' ' + err.message)  
          })  
  
        })  
    }.width('100%').margin({ top: 5 })  
  }  
}1.
