HarmonyOS鸿蒙Next中如何在应用内复制内容并粘贴到应用外

您看一下ShareOption的 LOCALDEVICE 表示允许在此设备中任何应用内粘贴。

参考连接：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-pasteboard-V5#shareoption9

您可以参考一下以下demo。

import { BusinessError, pasteboard } from '@kit.BasicServicesKit';
import { promptAction } from '@kit.ArkUI';

@Entry
@Component
struct Index14 {
  @State message: string = 'Hello World';

  build() {
    Column() {
      Text(this.message).onClick(() => {
        let pasteData: pasteboard.PasteData = pasteboard.createData(pasteboard.MIMETYPE_TEXT_PLAIN, this.message);
        let prop: pasteboard.PasteDataProperty = pasteData.getProperty();
        prop.shareOption = pasteboard.ShareOption.LOCALDEVICE;
        pasteData.setProperty(prop);
        let systemPasteboard: pasteboard.SystemPasteboard = pasteboard.getSystemPasteboard();
        systemPasteboard.setData(pasteData).then((data: void) => {
          promptAction.showToast({message:'复制成功'})
          console.info('Succeeded in setting PasteData.');
        }).catch((err: BusinessError) => {
          console.error('Failed to set PasteData. Cause: ' + err.message);
        });
      })
    }.width('100%').height('100%').justifyContent(FlexAlign.Center)
  }
}
