HarmonyOS 录屏禁用；是否正在录屏检测

监听参考：

手动判断截屏/录屏参考：

https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-display-V5#displayiscaptured12

1、配置权限："name": "ohos.permission.PRIVACY_WINDOW"

2、尝试以下demo：

import { BusinessError, deviceInfo } from '@kit.BasicServicesKit';
import { display, window } from '@kit.ArkUI';
@Entry
@Component
struct Index {
  async setPreventScreen() {
  let windowClass: window.Window = await window.getLastWindow(getContext(this))
  try {
    //设置防截屏录屏
    let promise = windowClass.setWindowPrivacyMode(true);
    promise.then(() => {
      console.info('-----成功-------');
    }).catch((err: BusinessError) => {
      console.error(`ErrorCode: ${err.code}, -----失败-------: ${err.message}`);
    })
  } catch (e) {
    console.info('避免录屏失败')
  }
}
  aboutToAppear(): void {
    this.setPreventScreen()
    let callback: Callback<boolean> = (captureStatus: boolean) => {
      console.info('-----监听------: ' + captureStatus);
    };
    display.on('captureStatusChange', callback);
  }

  build() {
    Row() {
      Column() {
        Button("是否在录屏")
          .onClick(() => {
            let ret: boolean = false;
            ret = display.isCaptured();
            console.info('-----手动判断------: ' + ret);
          })
      }
      .width('100%')
    }
    .height('100%')
  }
}
