CustomDialog是自定义弹出框，可用于广告、中奖、警告、软件更新等与用户交互响应操作。开发者可以通过CustomDialogController类显示自定义弹出框。

说明：

当前，ArkUI弹出框均为非页面级弹出框，在页面路由跳转时，如果开发者未调用close方法将其关闭，弹出框将不会自动关闭。若需实现在跳转页面时覆盖弹出框的场景，建议使用Navigation。

弹出框（CustomDialog）可以通过配置[isModal]来实现模态和非模态弹窗。isModal为true的时候，弹出框为模态弹窗。isModal为false时，弹出框为非模态弹窗。

创建自定义弹出框

1. 使用@CustomDialog装饰器装饰自定义弹出框，可在此装饰器内自定义弹出框内容。CustomDialogController需在@Component内定义。

   @CustomDialog
   struct CustomDialogExample {
     controller: CustomDialogController = new CustomDialogController({
       builder: CustomDialogExample({}),
     })
   
     build() {
       Column() {
         Text('我是内容')
           .fontSize(20)
           .margin({ top: 10, bottom: 10 })
       }
     }
   }
   ts
    class="hljs-button signin active" data-title="登录复制" data-report-click="{"spm":"1001.2101.3001.4334"}">

创建构造器，与装饰器呼应相连。

 @Entry
 @Component
 struct CustomDialogUser {
   dialogController: CustomDialogController = new CustomDialogController({
     builder: CustomDialogExample(),
   })
 }
ts
 class="hljs-button signin active" data-title="登录复制" data-report-click="{"spm":"1001.2101.3001.4334"}">

点击与onClick事件绑定的组件使弹出框弹出。

@Entry
@Component
struct CustomDialogUser {
  dialogController: CustomDialogController = new CustomDialogController({
    builder: CustomDialogExample(),
  })

  build() {
    Column() {
      Button('click me')
        .onClick(() => {
          this.dialogController.open()
        })
    }.width('100%').margin({ top: 5 })
  }
}
ts
 class="hljs-button signin active" data-title="登录复制" data-report-click="{"spm":"1001.2101.3001.4334"}">

弹出框的交互

弹出框可用于数据交互，完成用户一系列响应操作。

1. 在@CustomDialog装饰器内添加按钮，同时添加数据函数。

   @CustomDialog
   struct CustomDialogExample {
     cancel?: () => void
     confirm?: () => void
     controller: CustomDialogController
   
     build() {
       Column() {
         Text('我是内容').fontSize(20).margin({ top: 10, bottom: 10 })
         Flex({ justifyContent: FlexAlign.SpaceAround }) {
           Button('cancel')
             .onClick(() => {
               this.controller.close()
               if (this.cancel) {
                 this.cancel()
               }
             }).backgroundColor(0xffffff).fontColor(Color.Black)
           Button('confirm')
             .onClick(() => {
               this.controller.close()
               if (this.confirm) {
                 this.confirm()
               }
             }).backgroundColor(0xffffff).fontColor(Color.Red)
         }.margin({ bottom: 10 })
       }
     }
   }
   ts
    class="hljs-button signin active" data-title="登录复制" data-report-click="{"spm":"1001.2101.3001.4334"}">

弹出框的动画

弹出框通过定义openAnimation控制弹出框出现动画的持续时间，速度等参数。

@CustomDialog
struct CustomDialogExample {
  controller?: CustomDialogController

  build() {
    Column() {
      Text('Whether to change a text?').fontSize(16).margin({ bottom: 10 })
    }
  }
}

@Entry
@Component
struct CustomDialogUser {
  @State textValue: string = ''
  @State inputValue: string = 'click me'
  dialogController: CustomDialogController | null = new CustomDialogController({
    builder: CustomDialogExample(),
    openAnimation: {
      duration: 1200,
      curve: Curve.Friction,
      delay: 500,
      playMode: PlayMode.Alternate,
      onFinish: () => {
        console.info('play end')
      }
    },
    autoCancel: true,
    alignment: DialogAlignment.Bottom,
    offset: { dx: 0, dy: -20 },
    gridCount: 4,
    customStyle: false,
    backgroundColor: 0xd9ffffff,
    cornerRadius: 10,
  })

  // 在自定义组件即将析构销毁时将dialogController置空
  aboutToDisappear() {
    this.dialogController = null // 将dialogController置空
  }

  build() {
    Column() {
      Button(this.inputValue)
        .onClick(() => {
          if (this.dialogController != null) {
            this.dialogController.open()
          }
        }).backgroundColor(0x317aff)

弹出框的样式

弹出框通过定义宽度、高度、背景色、阴影等参数来控制样式。

@CustomDialog
struct CustomDialogExample {
  controller?: CustomDialogController

  build() {
    Column() {
      Text('我是内容').fontSize(16).margin({ bottom: 10 })
    }
  }
}

@Entry
@Component
struct CustomDialogUser {
  @State textValue: string = ''
  @State inputValue: string = 'click me'
  dialogController: CustomDialogController | null = new CustomDialogController({
    builder: CustomDialogExample(),
    autoCancel: true,
    alignment: DialogAlignment.Center,
    offset: { dx: 0, dy: -20 },
    gridCount: 4,
    customStyle: false,
    backgroundColor: 0xd9ffffff,
    cornerRadius: 20,
    width: '80%',
    height: '100px',
    borderWidth: 1,
    borderStyle: BorderStyle.Dashed,//使用borderStyle属性，需要和borderWidth属性一起使用
    borderColor: Color.Blue,//使用borderColor属性，需要和borderWidth属性一起使用
    shadow: ({ radius: 20, color: Color.Grey, offsetX: 50, offsetY: 0}),
  })

  // 在自定义组件即将析构销毁时将dialogController置空
  aboutToDisappear() {
    this.dialogController = null // 将dialogController置空
  }

  build() {
    Column() {
      Button(this.inputValue)
        .onClick(() => {
          if (this.dialogController != null) {
            this.dialogController.open()
          }
        }).backgroundColor(0x317aff)
    }.width('100%').margin({ top: 5 })

嵌套自定义弹出框

通过第一个弹出框打开第二个弹出框时，最好将第二个弹出框定义在第一个弹出框的父组件处，通过父组件传给第一个弹出框的回调来打开第二个弹出框。

@CustomDialog
struct CustomDialogExampleTwo {
  controllerTwo?: CustomDialogController
  @State message: string = "I'm the second dialog box."
  @State showIf: boolean = false;
  build() {
    Column() {
      if (this.showIf) {
        Text("Text")
          .fontSize(30)
          .height(100)
      }
      Text(this.message)
        .fontSize(30)
        .height(100)
      Button("Create Text")
        .onClick(()=>{
          this.showIf = true;
        })
      Button ('Close Second Dialog Box')
        .onClick(() => {
          if (this.controllerTwo != undefined) {
            this.controllerTwo.close()
          }
        })
        .margin(20)
    }
  }
}
@CustomDialog
struct CustomDialogExample {
  openSecondBox?: ()=>void
  controller?: CustomDialogController

  build() {
    Column() {
      Button ('Open Second Dialog Box and close this box')
        .onClick(() => {
          this.controller!.close();
          this.openSecondBox!();
        })
        .margin(20)
    }.borderRadius(10)
  }
}
@Entry
@Component
struct CustomDialogUser {
  @State inputValue: string = 'Click Me'
  dialogController: CustomDialogController | null = new CustomDialogController({
    builder: CustomDialogExample({
      openSecondBox: ()=>{
        if (this.dialogControllerTwo != null) {
          this.dialogControllerTwo.open()
        }
      }
    }),
    cancel: this.exitApp,
    autoCancel: true,

  aboutToDisappear() {
    this.dialogController = null
    this.dialogControllerTwo = null
  }

  onCancel() {
    console.info('Callback when the first button is clicked')
  }

  onAccept() {

由于自定义弹出框在状态管理侧有父子关系，如果将第二个弹出框定义在第一个弹出框内，那么当父组件（第一个弹出框）被销毁（关闭）时，子组件（第二个弹出框）内无法再继续创建新的组件。
