Answer 1

鸿蒙可以通过分布式能力实现跨设备协同

import {
  createCollaborationServiceMenuItems,
  CollaborationServiceStateDialog,
  CollaborationServiceFilter
} from '@kit.ServiceCollaborationKit';
import { image } from '@kit.ImageKit';
import { hilog } from '@kit.PerformanceAnalysisKit';

@Entry
@Component
struct Index {
  @State picture: PixelMap | undefined = undefined;

  @Builder
  MyTestMenu() {
    Menu() {
      createCollaborationServiceMenuItems([CollaborationServiceFilter.ALL], 30)
    }
  }

  build() {
    Column({ space: 20 }) {
      CollaborationServiceStateDialog({
        onState: (stateCode: number, bufferType: string, buffer: ArrayBuffer): void => this.doInsertPicture(stateCode, bufferType, buffer)
      })
      Button('使用远端设备进行拍照')
        .type(ButtonType.Normal)
        .borderRadius(10)
        .bindMenu(this.MyTestMenu)

      if (this.picture) {
        Image(this.picture)
          .borderStyle(BorderStyle.Dotted)
          .borderWidth(1)
          .objectFit(ImageFit.Contain)
          .height('80%')
          .onComplete((event) => {
            if (event != undefined) {
              hilog.info(0, "MEMOMOCK", "onComplete " + event.loadingStatus)
            }
          })
      }
    }
    .padding(20)
    .width('100%')
    .alignItems(HorizontalAlign.Center)
  }

  doInsertPicture(stateCode: number, bufferType: string, buffer: ArrayBuffer): void {
    if (stateCode != 0) {
      return
    }
    if (bufferType == "general.image") {
      let imageSource = image.createImageSource(buffer)
      imageSource.createPixelMap().then((pixelMap) => {
        this.picture = pixelMap;
      })
    }
  }
}
