是否有任何插件或扩展名为nativescript中的光滑照片?我尝试使用滑动方向,但我希望在照片上有平滑的滑动效果。谢谢:)

您想要一个水平滑块,用户可以从侧面滑动图像吗?
如果是这样,一个简单的ScrollView就可以了。
<Page>
<ScrollView orientation="horizontal">
<Image src="~/image1.png" />
<Image src="~/image2.png" />
<Image src="~/image3.png" />
<Image src="~/image4.png" />
</ScrollView>
</Page>
另请参阅ScrollView的文档:https://docs.nativescript.org/ApiReference/ui/scroll-view/HOW-TO.html

您可以将Gesture用于此过程
import { SwipeGestureEventData } from "ui/gestures";
export class XXX{
public direction: number;
private images:any[] = ["image url", "image url","image url","image url"];
public current_image;
private image_lenght;
private current_image_count=0;
constructor() {
this.image_lenght = this.images.length;
this.current_image = this.images[this.current_image_count];
}
private onSwipe(args: SwipeGestureEventData) {
direction = args.direction;
/*left to right direction = 1
right to left direction = 2
top to bottom direction = 8
bottom to top direction = 4*/
switch (this.direction) {
case 1:
if(this.current_image_count != 0)
this.current_image_count --;
break;
case 2:
if(this.current_image_count < (this.image_lenght) -1)
this.current_image_count ++;
break;
case 4:
// code...
break;
case 8:
// code.
break;
default:
// code...
break;
}
this.current_image = this.images[this.current_image_count];
}
}
