使用bindPopUp实现气泡弹窗效果

@Entry
@Component
struct BindPopupDemo {
  // 第一步：定义变量控制弹窗显示
  @State customPopup: boolean = false;

// 第二步：popup构造器定义弹框内容
  @Builder
  popupBuilder() {

build() {
    Column() {

Button('click')// 第四步：创建点击事件，控制弹窗显隐
        .onClick(() => {

        })
        .backgroundColor(0xf56c6c)// 第三步：使用bindPopup接口将弹窗内容绑定给元素
        .bindPopup(this.customPopup, {

})

}

.justifyContent(FlexAlign.Center)

.width('100%')

.height(437)

使用if实现模态转场

@Entry

@Component

struct ModalTransitionWithIf {

// 第一步：定义状态变量控制页面显示

@State isShowShare: boolean = false;

private shareFunc(): void {

this.getUIContext()?.animateTo({ duration: 500 }, () => {

build() {

// 第二步：定义Stack布局显示当前页面和模态页面

Stack() {

Column() {

Button('click').onClick(() => {

this.shareFunc();

// 第三步：在if中定义模态页面，显示在最上层，通过if控制模态页面出现消失

if (this.isShowShare) {

Column() {

Button('Close')

.onClick(() => {

this.shareFunc();

}

.width('100%')

.height('100%')

.backgroundColor(0xffffff)

.transition(TransitionEffect.OPACITY

.combine(TransitionEffect.translate({ x: '100%' }))

.combine(TransitionEffect.scale({ x: 0.95, y: 0.95 })))

}

共享元素转场
