HarmonyOS toggle点击后，状态变化的回调会跟随开关值变化

@Entry 
@Component 
struct Index { 
  @State isDarkMode: boolean = false 
 
  build() { 
    Column() { 
      Column() { 
        Toggle({ type: ToggleType.Switch, isOn: $$this.isDarkMode }) 
 
          .onChange((isOn: boolean) => { 
            console.info('Toggle.onChange:isOn' + isOn) 
            this.isDarkMode = isOn 
            getContext(this).getApplicationContext().setColorMode(this.isDarkMode ? 0 : 1) 
          }) 
      } 
      .hitTestBehavior(HitTestMode.Block) 
      .onClick(() => { 
        setTimeout(() => { 
          this.isDarkMode = !this.isDarkMode 
        }, 10000) 
      }) 
    }.width('100%').height('100%').padding(32) 
  } 
}
