HarmonyOS Image 点击问题

可以参考此demo：

@Entry
@Component
struct ImageExample3 {
  private imageOne: Resource = $r('app.media.1');
  private imageTwo: Resource = $r('app.media.2');
  @State src: Resource = this.imageOne
  @State eventType: string = '事件'
  build(){
    Column(){
      Text(this.eventType)
        .margin(20)

      Image(this.src)
        .width(100)
        .height(100)
        .onTouch((event?: TouchEvent) => {
          if(event){
            if (event.type === TouchType.Down) {
              this.eventType = 'Down'
              this.src = this.imageTwo
            }
            if (event.type === TouchType.Up) {
              this.eventType = 'Up'
              this.src = this.imageOne
            }
          }
        })
    }.width('100%').height('100%')
  }
}
