在HarmonyOS NEXT开发中防截屏实现？

Question

在HarmonyOS NEXT开发中防截屏实现？在某一个page里面开启防截屏，获取window需要做些什么操作吗？

Answer 1

参考以下步骤和demo：
1、在module.json5文件中声明需要使用的 ohos.permission.PRIVACY_WINDOW 权限，参考文档：https://developer.huawei.com/consumer/cn/doc/harmonyos-guides...
"requestPermissions": [
{

"name": "ohos.permission.PRIVACY_WINDOW" 

}
]
2.示例代码

// windowUtils.ets 
 
import window from '@ohos.window'; 
import common from '@ohos.app.ability.common'; 
export class windowUtils { 
  static setWindowPrivacyModeInPage(context: common.UIAbilityContext,isFlag: boolean) { 
    window.getLastWindow(context).then((lastWindow)=>{ 
      lastWindow.setWindowPrivacyMode(isFlag); 
    }) 
  } 
} 
//页面 
import common from '@ohos.app.ability.common'; 
import { windowUtils } from '../common/windowUtils'; 
@Entry 
@Component 
struct Index3 { 
  @State message: string = 'Hello World'; 
  onPageShow(): void { 
    windowUtils.setWindowPrivacyModeInPage(getContext(this) as common.UIAbilityContext, true); 
  } 
  onPageHide() { 
    windowUtils.setWindowPrivacyModeInPage(getContext(this) as common.UIAbilityContext,false); 
  } 
  build() { 
    Row() { 
      Column() { 
        Text(this.message) 
          .fontSize(50) 
          .fontWeight(FontWeight.Bold) 
      } 
      .width('100%') 
    } 
    .height('100%') 
  } 
}
