定义频率设置视图模型

// 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：

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：

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

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。

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。
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。
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。

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

案例整理

// 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

Toggle用于切换蓝牙开关状态。

// 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%')
  }
}

          console.info('Picker item changed, value: ' + value + ', index: ' + index)
        })
        .disappearTextStyle({ color: Color.Red, font: { size: 15, weight: FontWeight.Lighter } })
        .textStyle({ color: Color.Black, font: { size: 20, weight: FontWeight.Normal } })

  private fruits: string[] = ['apple1', 'orange2', 'peach3', 'grape4']

  build() {
    Column() {
      TextPicker({ range: this.fruits, selected: this.select })
        .onChange((value: string | string[], index: number | number[]) => {
          console.info('Picker item changed, value: ' + value + ', index: ' + index)
        })
        .disappearTextStyle({color: Color.Red, font: {size: 15, weight: FontWeight.Lighter}})
        .textStyle({color: Color.Black, font: {size: 20, weight: FontWeight.Normal}})
        .selectedTextStyle({color: Color.Blue, font: {size: 30, weight: FontWeight.Bolder}})
        .divider(null)
    }.width('100%').height('100%')
  }
}

@Entry
@Component
struct TextPicker04Page {
  private select: number = 1
  private fruits: string[] = ['apple1', 'orange2', 'peach3', 'grape4']

  build() {
    Column() {
      TextPicker({ range: this.fruits, selected: this.select })
        .onChange((value: string | string[], index: number | number[]) => {
          console.info('Picker item changed, value: ' + value + ', index: ' + index)
        })
        .disappearTextStyle({ color: Color.Red, font: { size: 15, weight: FontWeight.Lighter } })
        .textStyle({ color: Color.Black, font: { size: 20, weight: FontWeight.Normal } })
        .selectedTextStyle({ color: Color.Blue, font: { size: 30, weight: FontWeight.Bolder } })
        .divider({
          strokeWidth: 10,
          color: Color.Red,
          startMargin: 10,
          endMargin: 20
        } as DividerOptions)
    }
    .width('100%')
    .height('100%')
  }
}

        .onChange((value: string | string[], index: number | number[]) => {
          console.info('Picker item changed, value: ' + value + ', index: ' + index)
        })
        .disappearTextStyle({ color: Color.Red, font: { size: 15, weight: FontWeight.Lighter } })
        .textStyle({ color: Color.Black, font: { size: 20, weight: FontWeight.Normal } })
        .selectedTextStyle({ color: Color.Blue, font: { size: 30, weight: FontWeight.Bolder } })
        .gradientHeight(100)
    }.width('100%').height('100%')
  }
}

    Column() {
      Button('切换12小时制/24小时制')
        .margin(30)
        .onClick(() => {
          this.isMilitaryTime = !this.isMilitaryTime
        })

      TimePicker({
        selected: this.selectedTime,
        format: TimePickerFormat.HOUR_MINUTE_SECOND
      })
        .useMilitaryTime(this.isMilitaryTime)
        .onChange((value: TimePickerResult) => {
          if(value.hour >= 0) {
            this.selectedTime.setHours(value.hour, value.minute)
            console.info(`${value}`)
