定义频率设置视图模型

TypeScript 复制代码 
// ets/viewModel/FrequencySetting.ets

import { FrequencyContentType } from "../model/TaskInitList"

export function padTo2Digits(num: number) {
  return num.toString().padStart(2, '0')
}

const chineseNumOfWeek: string[] = ['一', '二', '三', '四', '五', '六', '日']
const WEEK: string = '星期'

export const frequencyRange = () => {
  const frequencyRangeArr: FrequencyContentType[] = []
  chineseNumOfWeek.forEach((item: string, index: number) => {
    frequencyRangeArr.push({
      id: (index + 1),
      label: `${WEEK}${item}`,
      isChecked: false
    })
  })
  return frequencyRangeArr
}

基础知识：切换按钮 (Toggle)

Toggle组件提供状态按钮样式、勾选框样式和开关样式，一般用于两种状态之间的切换。

创建切换按钮

Toggle通过调用接口来创建，接口调用形式如下：

TypeScript 复制代码 
Toggle(options: { type: ToggleType, isOn?: boolean })

其中，ToggleType为开关类型，包括Button、Checkbox和Switch，isOn为切换按钮的状态。

API version 11开始，Checkbox默认样式由圆角方形变为圆形。

接口调用有以下两种形式：

  • 创建不包含子组件的Toggle。

当ToggleType为Checkbox或者Switch时，用于创建不包含子组件的Toggle：

TypeScript 复制代码 
Toggle({ type: ToggleType.Checkbox, isOn: false })
Toggle({ type: ToggleType.Checkbox, isOn: true })
TypeScript 复制代码 
Toggle({ type: ToggleType.Switch, isOn: false })
Toggle({ type: ToggleType.Switch, isOn: true })
  • 创建包含子组件的Toggle。

当ToggleType为Button时，只能包含一个子组件，如果子组件有文本设置，则相应的文本内容会显示在按钮上。

TypeScript 复制代码 
Toggle({ type: ToggleType.Button, isOn: false }) {
  Text('status button')
    .fontColor('#182431')
    .fontSize(12)
}.width(100)
Toggle({ type: ToggleType.Button, isOn: true }) {
  Text('status button')
    .fontColor('#182431')
    .fontSize(12)
}.width(100)

自定义样式

  • 通过selectedColor属性设置Toggle打开选中后的背景颜色。
TypeScript 复制代码 
Toggle({ type: ToggleType.Button, isOn: true }) {
  Text('status button')
    .fontColor('#182431')
    .fontSize(12)
}.width(100).selectedColor(Color.Pink)
Toggle({ type: ToggleType.Checkbox, isOn: true })
  .selectedColor(Color.Pink)
Toggle({ type: ToggleType.Switch, isOn: true })
  .selectedColor(Color.Pink)
  • 通过switchPointColor属性设置Switch类型的圆形滑块颜色，仅对type为ToggleType.Switch生效。
TypeScript 复制代码 
Toggle({ type: ToggleType.Switch, isOn: false })
  .switchPointColor(Color.Pink)
Toggle({ type: ToggleType.Switch, isOn: true })
  .switchPointColor(Color.Pink)

添加事件

除支持通用事件外，Toggle还用于选中和取消选中后触发某些操作，可以绑定onChange事件来响应操作后的自定义行为。

TypeScript 复制代码 
Toggle({ type: ToggleType.Switch, isOn: false })
  .onChange((isOn: boolean) => {
    if(isOn) {
      // 需要执行的操作
    }
  })

案例整理

TypeScript 复制代码 
// ets/pages/toggle/usagePage.ets

@Entry
@Component
struct usagePage {
  @State isOn: boolean = true

  build() {
    Column({ space: 20 }) {
      Row() {
        Toggle({ type: ToggleType.Checkbox, isOn: false })
        Toggle({ type: ToggleType.Checkbox, isOn: true })
      }

      Row() {
        Toggle({ type: ToggleType.Switch, isOn: false })
        Toggle({ type: ToggleType.Switch, isOn: true })
      }

      Row() {
        Toggle({ type: ToggleType.Button, isOn: false }) {
          Text('status button')
            .fontColor('#182431')
            .fontSize(12)
        }.width(100)
        Toggle({ type: ToggleType.Button, isOn: true }) {
          Text('status button')
            .fontColor('#182431')
            .fontSize(12)
        }.width(100)
      }

      Row() {
        Toggle({ type: ToggleType.Button, isOn: true }) {
          Text('status button')
            .fontColor('#182431')
            .fontSize(12)
        }.width(100).selectedColor(Color.Orange)

        Toggle({ type: ToggleType.Checkbox, isOn: true })
          .selectedColor(Color.Orange)

        Toggle({ type: ToggleType.Switch, isOn: true })
          .selectedColor(Color.Orange)
      }

      Row() {
        Toggle({ type: ToggleType.Switch, isOn: false })
          .switchPointColor(Color.Orange)
        Toggle({ type: ToggleType.Switch, isOn: true })
          .switchPointColor(Color.Orange)
      }

      Row() {
        Toggle({ type: ToggleType.Switch, isOn: this.isOn })
          .onChange((isOn: boolean) => {
              this.isOn = !this.isOn
          })
        Text(`${this.isOn}`)
      }

    }
    .width('100%')
  }
}

场景示例

TypeScript 复制代码 
// ets/pages/toggle/CasePage.ets

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

@Entry
@Component
struct CasePage {
  @State BOnSt: promptAction.ShowToastOptions = { 'message': 'Bluetooth is on.' }
  @State BOffSt: promptAction.ShowToastOptions = { 'message': 'Bluetooth is off.' }

  build() {
    Column() {
      Row() {
        Text("Bluetooth Mode")
          .height(50)
          .fontSize(16)
      }

      Row() {
        Text("Bluetooth")
          .height(50)
          .padding({ left: 10 })
          .fontSize(16)
          .textAlign(TextAlign.Start)
          .backgroundColor(0xFFFFFF)
        
        Toggle({ type: ToggleType.Switch })
          .margin({ left: 200, right: 10 })
          .onChange((isOn: boolean) => {
            if (isOn) {
              promptAction.showToast(this.BOnSt)
            } else {
              promptAction.showToast(this.BOffSt)
            }
          })
      }
      .backgroundColor(0xFFFFFF)
    }
    .padding(10)
    .backgroundColor(0xDCDCDC)
    .width('100%')
    .height('100%')
  }
}

        .divider({
          strokeWidth: 10,
          color: Color.Red,
          startMargin: 10,
          endMargin: 20
        } as DividerOptions)
    }
    .width('100%')
    .height('100%')
  }
}
