#鸿蒙通关秘籍#如何在鸿蒙自定义视图中实现滑动手势切换页面？

在鸿蒙应用中，可以通过PanGesture实现滑动手势切换页面，具体实现步骤如下：

typescript PanGesture(this.panOption) .onActionUpdate((event: GestureEvent) => { if (!this.isStartAction) { this.isStartAction = true; if (event.offsetX < this.judgmentValue) { if (this.currentIndex < this.titleArray.length - this.currentIndexRadix) { let temIndex: number = this.currentIndex + this.currentIndexRadix; this.scroller.scrollToIndex(temIndex, true, ScrollAlign.START); this.wantGoIndex = temIndex; animateTo({ duration: Math.abs(temIndex - this.currentIndex) * this.durationRadix, curve: Curve.EaseInOut, iterations: this.iterationsDefault, playMode: PlayMode.Normal, onFinish: () => { this.currentIndex = temIndex; } }, () => { this.transitionX = this.getTransitionX(temIndex); }) } } else { if (this.currentIndex > this.judgmentValue) { let temIndex: number = this.currentIndex - this.currentIndexRadix; this.scroller.scrollToIndex(temIndex, true, ScrollAlign.START); this.wantGoIndex = temIndex; animateTo({ duration: Math.abs(temIndex - this.currentIndex) * this.durationRadix, curve: Curve.EaseInOut, iterations: this.iterationsDefault, playMode: PlayMode.Normal, onFinish: () => { this.currentIndex = temIndex; } }, () => { this.transitionX = this.getTransitionX(temIndex); }) } } } })

使用PanGesture监听用户的滑动手势，根据滑动方向和距离判断是否切换页面，利用animateTo实现切换效果。
