Navigation实现一镜到底转场 原创
一、介绍
共享元素转场是一种界面切换时对相同或者相似的两个元素做的一种位置和大小匹配的过渡动画效果,也称一镜到底动效。
利用系统能力,转场前后两个组件调用geometryTransition接口绑定同一id,同时将转场逻辑置于animateTo动画闭包内,这样系统侧会自动为二者添加一镜到底的过渡效果。
系统将调整绑定的两个组件的宽高及位置至相同值,并切换二者的透明度,以实现一镜到底过渡效果。因此,为了实现流畅的动画效果,需要确保对绑定geometryTransition的节点添加宽高动画不会有跳变。此方式适用于创建新节点开销小的场景
效果图如下
二、设计思路
我们设计两个页面。PageOne用来显示九宫格图片,PageTwo用来显示大图。
PageOne使用Grid来作为容器,GridItem放置Image组件。
我们找到9张图片放到资源目录中,为Image配置geometryTransition()参数为字符串,作为当前图片的共享元素id。
PageTwo页面我们是哟个Swiper作为容器,其中每个Item我们放置一个可以带缩放功能的Image组件,缩放功能可以找到三方组件替代。此Image也需要配置geometryTransition(),参数与PageOne中对应的图片的id保持一致。
点击PageOne中某一张图片和PageTwo返回上一页面时,我们使用animateTo作为转场动画。
三、逻辑实现
(1)Navigation配置NavPathStack
@Provide('NavPathStack') pageInfos: NavPathStack = new NavPathStack();
Navigation(this.pageInfos) {
}
(2)配置路由
resources->base->profile下配置route_map.json文件
{
"routerMap": [
{
"name": "pageTwo",//名称,根据此参数进行跳转
"pageSourceFile": "src/main/ets/pages/PageTwo.ets",//目标页面路径
"buildFunction": "PageTwoBuilder"
}
]
}
moudule.json5文件引入路由配置文件
{
"module": {
"routerMap": "$profile:route_map"
}
}
(3)PageOne页面配置转场动画和共享元素,使用状态变量来控制跳转过程中,PageOne被放大的图片显示空白
Grid(this.scroller) {
ForEach(this.data, (item: Resource, index: number) => {
GridItem() {
if (this.clickedIndex !== index || (this.isFirstPageShow)) {
Image(item)
.width('100%')
.height('100%')
.objectFit(ImageFit.Cover)
.onClick(() => {
this.onItemClick(index)
})
.geometryTransition('app.media.img_' + JSON.stringify(index % 9))
.transition(TransitionEffect.opacity(0.99))
}
}
.width(px2vp(381))
.height(px2vp(381))
}, (item: number) => item + '')
}
.rowsTemplate('1fr 1fr 1fr')
.columnsTemplate('1fr 1fr 1fr')
onItemClick(index: number) {
let param: Record<string, Object> = {};
this.clickedIndex = index;
param['selectedIndex'] = this.clickedIndex;
param['bigImageData'] = this.data
param['onIndexChange'] = (index: number) => {
this.onIndexChange(index);
};
param['onBackToFirstPage'] = () => {
this.onBack();
}
animateTo({
duration: 250,
curve: Curve.EaseIn,
}, () => {
this.pageInfos.pushPath({ name: 'pageTwo', param: param }, false);
this.isFirstPageShow = false;
})
}
(4)PageTwo页面配置共享元素id和返回上一页转场动画
Swiper(this.swiperController) {
ForEach(this.bigImageData, (item: Resource, index: number) => {
PhotoItem({
//配置共享元素id
imageUrl: 'app.media.img_' + JSON.stringify(index % 9),
backToFirstPage: this.backToFirstPage
})
}, (item: string) => item)
}
private backToFirstPage: () => void = () => {
animateTo({
duration: 300,
curve: Curve.EaseIn,
}, () => {
this.onFirstPageShow();
this.pageInfos.pop(false);
})
}
