如何在bindSheet中实现页面切换的效果

分类：HBuilderX

问题现象
在使用bindSheet时，只能显示一个弹窗内容，如何在bindSheet中实现页面切换的效果？

背景知识
bindSheet：半模态页面（bindSheet）默认是模态形式的非全屏弹窗式交互页面，允许部分底层父视图可见，帮助用户在与半模态交互时保留其父视图环境。半模态页面适用于展示简单的任务或信息面板，例如，个人信息、文本简介、分享面板、创建日程、添加内容等。若需展示可能影响父视图的半模态页面，半模态支持配置为非模态交互形式。
onAreaChange：组件区域变化时触发该回调。仅会响应由布局变化所导致的组件大小、位置发生变化时的回调。
animateTo：提供animateTo接口来指定由于闭包代码导致的状态变化插入过渡动效。
translate：设置页面转场时的平移效果。
解决方案
实现思路如下：

半模态页面实现：使用Stack容器层叠布局两个组件，通过@State变量动态控制组件显隐状态，从而实现组件切换。
动画效果优化：为组件绑定onClick点击事件，使用animateTo设置动画持续时间，再指定由于闭包代码导致的状态变化插入过渡动效。
.onClick(() => {
this.title = '子集标题';
this.getUIContext()?.animateTo({
duration: 800, // 动画持续时间，单位为毫秒。
curve: Curve.EaseOut, // 动画曲线。
playMode: PlayMode.Normal, // 动画播放模式，默认播放完成后重头开始播放。默认值：PlayMode.Normal
onFinish: () => {
console.info('play end');
}
}, () => {
// 指定显示动效的闭包函数，在闭包函数中导致的状态变化系统会自动插入过渡动画。
this.flag = !this.flag;
});
});

页面切换实现：translate属性实现页面切换效果，平移距离通过onAreaChange回调动态获取弹窗宽度，避免不同设备动画的移动尺寸不同。
SheetBuilder2({ title: this.title, flag: this.flag })
.width('100%')
.height('100%')
.translate(this.flag ? { x: 0 } : { x: this.translateX })
.onAreaChange((oldValue: Area, newValue: Area) => {
console.info('testTag', 获取到oldValue、newValue:${oldValue.width}、${newValue.width});
// 适配其他尺寸设备时，使用onAreaChange获取宽度，动画的移动尺寸直接取弹窗的宽度。
this.translateX = newValue.width as number;
});
完整代码如下：

@Entry
@Component
struct SheetDemo {
@State isShowSheet: boolean = false;
private items: number[] = [0, 1, 2, 3, 4];
@State title: string = '标题';
@State flag: boolean = false;
@State translateX: number = 0;

@Builder
SheetBuilder() {
Stack() {

  Column() {  
    Row() {  
      Text(this.title);  
    }  
    .padding({ left: 20, right: 20 })  
    .height('50')  
    .width('100%');  

    List({ space: '10vp' }) {  
      ForEach(this.items, (item: number) => {  
        ListItem() {  
          Text(String(item)).fontSize(16).fontWeight(FontWeight.Bold);  
        }  
        .width('90%')  
        .height('80vp')  
        .backgroundColor('#E5E5E5')  
        .borderRadius(10)  
        .onClick(() => {  
          this.title = '子集标题';  
          this.getUIContext()?.animateTo({  
            duration: 800, // 动画持续时间，单位为毫秒。  
            curve: Curve.EaseOut, // 动画曲线。  
            playMode: PlayMode.Normal, // 动画播放模式，默认播放完成后重头开始播放。  默认值：PlayMode.Normal  
            onFinish: () => {  
              console.info('play end');  
            }  
          }, () => {  
            // 指定显示动效的闭包函数，在闭包函数中导致的状态变化系统会自动插入过渡动画。  
            this.flag = !this.flag;  
          });  
        });  

      });  
    }  
    .alignListItem(ListItemAlign.Center)  
    .margin({ top: '10vp' })  
    .width('100%')  
    .height('100%');  
  }.width('100%').height('100%')  
  .translate(this.flag ? { x: -this.translateX } : { x: 0 });  

  SheetBuilder2({ title: this.title, flag: this.flag })  
    .width('100%')  
    .height('100%')  
    .translate(this.flag ? { x: 0 } : { x: this.translateX })  
    .onAreaChange((oldValue: Area, newValue: Area) => {  
      console.info('testTag', `获取到oldValue、newValue:${oldValue.width}、${newValue.width}`);  
      // 适配其他尺寸设备时，使用onAreaChange获取宽度，动画的移动尺寸直接取弹窗的宽度。  
      this.translateX = newValue.width as number;  
    });  

};

}

build() {

Column() {  
  Button('Open Sheet').width('90%')  
    .onClick(() => {  
      this.isShowSheet = !this.isShowSheet;  
    })  
    .bindSheet($$this.isShowSheet, this.SheetBuilder(), {  
      detents: [SheetSize.MEDIUM, SheetSize.LARGE, 600],  
      preferType: SheetType.BOTTOM,  
    });  
}.width('100%').height('100%')  
.justifyContent(FlexAlign.Center);

}
}

@Component
struct SheetBuilder2 {
@Link title: string;
@Link flag: boolean;

build() {
Column() {
Row() {
Column() {
Image($r('sys.media.ohos_ic_compnent_titlebar_back'))
.height(24)
.width(24)
.fillColor('#313232');

    }  
    .borderRadius(40)  
    .width(40)  
    .height(40)  
    .justifyContent(FlexAlign.Center)  
    .alignItems(HorizontalAlign.Center)  
    .backgroundColor('#e6e8e9')  
    .margin({ right: 8 })  
    .onClick(() => {  
      this.title = '标题';  
      this.getUIContext()?.animateTo({  
        duration: 500,  
        curve: Curve.EaseOut,  
        playMode: PlayMode.Normal,  
        onFinish: () => {  
          console.info('play end');  
        }  
      }, () => {  
        this.flag = !this.flag;  
      });  
    });  
    Text(this.title);  
  }  
  .height('50')  
  .width('100%');  
  Column() {  
    Text('子集页面');  
  }  
  .justifyContent(FlexAlign.Center)  
  .alignItems(HorizontalAlign.Center)  
  .width('100%')  
  .layoutWeight(1);  
}.width('100%').height('100%').padding({ right: 18, left: 18 });

}
