如题：toggle组件设置拖动的同时如何屏蔽其本身的点击手势？

Answer 1

需要手动控制Toggle组件传入的默认值，例如在最上面自定义一个toggleIsOn的boolean变量然后，在onChange回调里面自己手动控制改变其的值。

import { hilog } from '@kit.PerformanceAnalysisKit';

@Entry
@Component
export struct TestDragToggle {
  @State offsetX: number = 0;
  @State offsetY: number = 0;
  @State positionX: number = 0;
  @State positionY: number = 0;
  @State toggleIsOn: boolean = true;
  private isDragging: boolean = false;

  build() {
    Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center }) {
      Toggle({ type: ToggleType.Button, isOn: this.toggleIsOn }) {
        Text('Toggle')
      }
      .selectedColor(Color.Pink)
      // onchange回调先于onActionEnd
      .onChange((isOn: boolean) => {
        hilog.info(0x0000, 'testTag', 'xxx %{public}s', `onClick Toggle, isOn: ${isOn}`);
        console.info('isDragging======' + this.isDragging)
        if (isOn == this.toggleIsOn) {
          return
        } else {
          this.toggleIsOn = isOn
        }
        if (this.isDragging) {
          this.toggleIsOn = !this.toggleIsOn
        }
      })
      .translate({ x: this.offsetX, y: this.offsetY })
      .gesture(
        PanGesture()
          .onActionStart((event: GestureEvent) => {
            this.isDragging = true;
          })
          .onActionUpdate((event: GestureEvent) => {
            this.offsetX = this.positionX + event.offsetX;
            this.offsetY = this.positionY + event.offsetY;
          })
          .onActionEnd((event: GestureEvent) => {
            this.positionX = this.offsetX;
            this.positionY = this.offsetY;
            this.isDragging = false;
          })
      )
    }
  }
}
