OpenHarmony应用如何使用bindSheet属性为组件绑定半模态页面
简介：
为组件绑定半模态页面可以使用.bindSheet属性。
文档环境：
- 开发环境：Windows 11家庭版
- DevEco Studio版本：DevEco Studio 3.1.1 Release (3.1.0.501)
- SDK版本：4.1.6.1 Beta1(full sdk)
- 开发板型号：DAYU200(RK3568)
- 系统版本：OpenHarmony 4.1.6.1
演示demo：
-
新建一个 Stage 框架的 demo 工程，在page/Index.ets中新增组件控制半模态页面的各种属性：允许开发者配置所在页面是否允许交互、设置弹出的半模态页面的切换高度档位、设置弹出的半模态弹出样式、设置弹出的半模态所在页面是否显示关闭图标、设置弹出的半模态页面是否使用模糊背景。
-
新增Button按钮，使用.bindSheet绑定上述半模态页面。
核心代码如下：
import { TitleBar } from '../../../../common/TitleBar'
import { IntroductionTitle } from '../../../../common/IntroductionTitle'
import promptAction from '@ohos.promptAction';
import { BusinessError } from '@ohos.base';
import Logger from '../../../../util/Logger';
// 自定义半模态页面高度
const SIZE: number = 200;
@Extend(Text) function textStyle() {
.fontFamily('HarmonyHeiTi-Medium')
.fontSize(16)
.fontColor('#182431')
.textAlign(TextAlign.Start)
.lineHeight(22)
.fontWeight(500)
}
interface SheetSizes {
medium: boolean;
large: boolean;
size200: boolean;
}
@Entry
@Component
