image组件如何使用多态样式stateStyles中的selected选中状态

@State imageSrc: Resource | string = $r('app.media.startIcon') 
 
Image(this.imageSrc) 
  .onClick(() => { 
    if (this.imageSrc == 'A') { 
      this.imageSrc = 'B' 
    } else { 
      this.imageSrc = 'A' 
    } 
  }) 
Image(this.imageSrc == 0 ? $r('app.media.startIcon') : $r('app.media.icon')) 
  .onClick(() => { 
    if (this.imageSrc == 1) { 
      this.imageSrc = 0 
    } else { 
      this.imageSrc = 1 
    } 
  })
