NOTE
Percentage values are not supported. The value specified is used only when it is greater than or equal to 0.
If the value is not specified or the specified one is less than 0, the radius is set using the following formula:
(Component height (in vp)/2) - (2 vp x Component height (in vp)/20 vp)
unselectedColor ResourceColor No Yes Background color of the component when it is of the Switch type and is disabled.

Example

Example 1: Setting the Toggle Style

This example demonstrates how to configure the style for different types of toggles (checkbox, switch, and button) using ToggleType.

// xxx.ets
@Entry
@Component
struct ToggleExample {
  build() {
    Column({ space: 10 }) {
      Text('type: Switch').fontSize(12).fontColor(0xcccccc).width('90%')
      Flex({ justifyContent: FlexAlign.SpaceEvenly, alignItems: ItemAlign.Center }) {
        Toggle({ type: ToggleType.Switch, isOn: false })
          .selectedColor('#007DFF')
          .switchPointColor('#FFFFFF')
          .onChange((isOn: boolean) => {
            console.info('Component status:' + isOn);
          })

        Toggle({ type: ToggleType.Switch, isOn: true })
          .selectedColor('#007DFF')
          .switchPointColor('#FFFFFF')
          .onChange((isOn: boolean) => {
            console.info('Component status:' + isOn);
          })
      }

      Text('type: Checkbox').fontSize(12).fontColor(0xcccccc).width('90%')
      Flex({ justifyContent: FlexAlign.SpaceEvenly, alignItems: ItemAlign.Center }) {
        Toggle({ type: ToggleType.Checkbox, isOn: false })
          .size({ width: 20, height: 20 })
          .selectedColor('#007DFF')
          .onChange((isOn: boolean) => {
            console.info('Component status:' + isOn);
          })

        Toggle({ type: ToggleType.Checkbox, isOn: true })
          .size({ width: 20, height: 20 })
          .selectedColor('#007DFF')
          .onChange((isOn: boolean) => {
            console.info('Component status:' + isOn);
          })
      }

      Text('type: Button').fontSize(12).fontColor(0xcccccc).width('90%')
      Flex({ justifyContent: FlexAlign.SpaceEvenly, alignItems: ItemAlign.Center }) {
        Toggle({ type: ToggleType.Button, isOn: false }) {
          Text('status button').fontColor('#182431').fontSize(12)
        }.width(106)
        .selectedColor('rgba(0,125,255,0.20)')
        .onChange((isOn: boolean) => {
          console.info('Component status:' + isOn);
        })

        Toggle({ type: ToggleType.Button, isOn: true }) {
          Text('status button').fontColor('#182431').fontSize(12)
        }.width(106)
        .selectedColor('rgba(0,125,255,0.20)')
        .onChange((isOn: boolean) => {
          console.info('Component status:' + isOn);
        })
      }
    }.width('100%').padding(24)
  }
}

Example 2: Customizing the Toggle Style

This example implements a toggle of the Switch type with custom settings, including the radius and color of the circular slider, background color in the off state, and radius of the slider track border corners.

// xxx.ets
@Entry
@Component
struct ToggleExample {
  build() {
    Column({ space: 10 }) {
      Text('type: Switch').fontSize(12).fontColor(0xcccccc).width('90%')
      Flex({ justifyContent: FlexAlign.SpaceEvenly, alignItems: ItemAlign.Center }) {
        Toggle({ type: ToggleType.Switch, isOn: false })
          .selectedColor('#007DFF')
          .switchStyle({
            pointRadius: 15,
            trackBorderRadius: 10,
            pointColor: '#D2B48C',
            unselectedColor: Color.Pink })
          .onChange((isOn: boolean) => {
            console.info('Component status:' + isOn);
          })

        Toggle({ type: ToggleType.Switch, isOn: true })
          .selectedColor('#007DFF')
          .switchStyle({
            pointRadius: 15,
            trackBorderRadius: 10,
            pointColor: '#D2B48C',
            unselectedColor: Color.Pink })
          .onChange((isOn: boolean) => {
            console.info('Component status:' + isOn);
          })
      }
    }.width('100%').padding(24)
  }
}

Example 3: Implementing a Custom Toggle Style

This example shows how to implement a custom toggle style. The toggle button switches the background color. Clicking the blue circle changes the background to blue. Clicking the yellow circle changes it to yellow.

// xxx.ets
class MySwitchStyle implements ContentModifier<ToggleConfiguration> {
  selectedColor: Color = Color.White;
  lamp: string = 'string';

  constructor(selectedColor: Color, lamp: string) {
    this.selectedColor = selectedColor;
    this.lamp = lamp;
  }

  applyContent(): WrappedBuilder<[ToggleConfiguration]> {
    return wrapBuilder(buildSwitch);
  }
}

@Builder
function buildSwitch(config: ToggleConfiguration) {
  Column({ space: 50 }) {
    Circle({ width: 150, height: 150 })
      .fill(config.isOn ? (config.contentModifier as MySwitchStyle).selectedColor : Color.Blue)
    Row() {
      Button('Blue ' + JSON.stringify((config.contentModifier as MySwitchStyle).lamp))
        .onClick(() => {
          config.triggerChange(false);
        })
      Button('Yellow ' + JSON.stringify((config.contentModifier as MySwitchStyle).lamp))
        .onClick(() => {
          config.triggerChange(true);
        })
    }
  }
}

@Entry
@Component
struct Index {
  build() {
    Column({ space: 50 }) {
      Toggle({ type: ToggleType.Switch })
        .enabled(true)
        .contentModifier(new MySwitchStyle(Color.Yellow, 'light'))
        .onChange((isOn: boolean) => {
          console.info('Switch Log:' + isOn);
        })
    }.height('100%').width('100%')
  }
}
