鸿蒙onTouch拖拽进度条更新PAGViewController画面卡顿，有没有什么优化方法？

[qianyunrumo]

PAGViewV2({ controller: this.controller.viewController })
.width("100%")
.height("100%")
Row()
.onTouch((e: TouchEvent) => {
this.ctx.postFrameCallback(new MyFrameCallback(() => {
this.controller.touch(e);
}))
})
目前是使用UIContext的postFrameCallback进行了一个触摸优化，但是还是过于卡顿了
touch = (e: TouchEvent) => {
let x = e.touches[0].x;
let viewController = this.viewController;
switch (e.type) {
case TouchType.Down: {
this.startX = x;
}
break;
case TouchType.Move: {
if (this.startX == x) {
return;
}
this.startX = x;
let value = Math.max(0, Math.min(x, this.width)) / this.width;
this.current = value * 100;
viewController.setProgress(value);
viewController.play();
viewController.pause();
}
break;
}
}
