#鸿蒙通关秘籍#请教一下，ArkUI中菜单控制器怎么获取，有谁知道不？

哈哈，ArkUI中获取菜单控制器，你可以使用getContextMenuController函数，通过它来管理和关闭上下文菜单。 这个 demo 通过定时器触发，调用ContextMenuController的close方法关闭菜单

import { ContextMenuController } from '@kit.ArkUI';

@Entry
@Component
struct Index {
    menu: ContextMenuController = this.getUIContext().getContextMenuController();

    @Builder MenuBuilder() {
        Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {
            Button('Test ContextMenu1 Close')
            Divider().strokeWidth(2).margin(5).color(Color.Black)
            Button('Test ContextMenu2')
            Divider().strokeWidth(2).margin(5).color(Color.Black)
            Button('Test ContextMenu3')
        }
        .width(200)
        .height(160)
    }

    build() {
        Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {
            Button("启动定时器").onClick(()=>
            {
                setTimeout(() => {
                    this.menu.close();
                }, 10000);
            })

            Column() {
                Text("Test ContextMenu close")
                .fontSize(20)
                .width('100%')
                .height(500)
                .backgroundColor(0xAFEEEE)
                .textAlign(TextAlign.Center)
            }
            .bindContextMenu(this.MenuBuilder, ResponseType.LongPress)
        }
        .width('100%')
        .height('100%')
    }
}
