场景 app冷启动/热启动-有广告需求就打开广告页没有的话就去登录或者主页
有的app有的需要广告页有的不需要搞个配置呗
通过首选项配置存储我们的一些常用配置比如要不要广告页还有广告页的路由地址点击广告页跳转的链接广告页倒计时的秒数在入口处进行判断是否需要广告页需要的话跳转广告页-广告页根据设置的参数进行渲染广告页能不能设置--- 因为运营人员肯定不能每次都去改我们底层的代码-这里我还可以设置成动态的-就是初始化的时候通过请求去读一下云端的请求然后把我们的图片和一些参数配置下来这样每次你启动app就是运营人员给你配置的广告和设置了
1.新建一个关于广告类的数据模型
export class AdvertClass {showAd: boolean false // 是否展示广告isFull: boolean true // 是否全屏adTime: number 5 // 倒计时数据adUrl?: string // 要跳转的连接adImg?: ResourceStr // 图片连接
}// 全屏广告 半屏广告
2.在utils中新建一个关于读取首选项的类用来读取和设置首选项的广告设置- utils/setting.ets export const defaultAd: AdvertClass {showAd: true,isFull: true,adTime: 5,adImg: $r([basic].media.start)
}export const USER_SETTING fast_driver_setting // 用来存储用户设置的首选项的keyexport const USER_SETTING_AD fast_driver_setting_ad // 用来存储用户设置广告首选项的key// 负责首选项的读取
export class UserSetting {context: Contextconstructor(context: Context) {this.context context}// 获取仓库getStore() {return preferences.getPreferencesSync(this.context || getContext(), {name: USER_SETTING})}// 设置用户广告async setUserAd(ad: AdvertClass) {const store this.getStore()store.putSync(USER_SETTING_AD, ad)await store.flush() // 让外界能够控制自己的流程}// 获取用户广告getUserAd() {const store this.getStore()return store.getSync(USER_SETTING_AD, defaultAd) as AdvertClass}
}export const userSetting new UserSetting(getContext()) // 导出一个单例
3.实现Start页的页面结构及倒计时逻辑
import { window } from kit.ArkUI
import { AdvertClass, UserSetting } from homeEntry
Component
struct Start {userSetting: UserSetting new UserSetting(getContext(this))StateadObj: AdvertClass {showAd: false,adTime: 0}timer: number -1closeWin() {window.findWindow(ad_window).destroyWindow()}async aboutToAppear() {this.adObj await this.userSetting.getUserAd()this.timer setInterval(() {if (this.adObj.adTime 0) {clearInterval(this.timer)this.closeWin()return}this.adObj.adTime--}, 1000)}aboutToDisappear(): void {clearInterval(this.timer)}build() {Stack({ alignContent: Alignment.TopEnd }) {Image(this.adObj.adImg).objectFit(ImageFit.Cover)Text(${this.adObj.adTime}秒后跳过).padding({ left: 10, right: 10 }).margin({ right: 20, top: 20 }).height(30).fontSize(14).borderRadius(15).backgroundColor($r([basic].color.MW)).textAlign(TextAlign.Center).onClick(() {this.closeWin()})}.height(100%).width(100%).padding({ top: 40 })}
}4.封装window窗口广告模式
import { display, window } from kit.ArkUI
import { util } from kit.ArkTSexport class AdManager {context?: Context // 是给ability使用的private winNames: string [] []// 展示广告 采用windows窗口的创建和销毁的方式async showAd(url: string, width?: number, height?: number) {if (url) {let name win_${util.generateRandomUUID()}const win await window.createWindow({name,windowType: window.WindowType.TYPE_DIALOG,ctx: this.context || getContext()})if (width width 320 height height 240) {const screen display.getDefaultDisplaySync()let mainWidth vp2px(width)let mainHeight vp2px(height)win.resizeAsync(mainWidth, mainHeight)win.moveWindowToAsync((screen.width - mainWidth) / 2, (screen.height - mainHeight) / 2)}await win.showWindow() // 展示窗口win.setUIContent(url) // 设置地址this.winNames.push(name)return name}return }// 关闭广告async closeAd(name?: string) {if (name) {window.findWindow(name).destroyWindow()this.winNames this.winNames.filter(item item ! name) //清空数组内容} else {// 不传就认为 想关闭所有let index 0while (index this.winNames.length) {await window.findWindow(this.winNames[index]).destroyWindow()index}this.winNames [] // 清空数组}}
}export const adManger new AdManager()
5.采用与页面解耦的模式实现广告
import { AdvertClass } from ../viewmodels
import { ComponentContent, promptAction, window } from kit.ArkUI
import { util } from kit.ArkTS// 展示广告的结构最重要写的代码
Builder
function AdBuilder(ad: AdvertClass) {Column() {Image(ad.adImg).width(100%).height(100%).objectFit(ImageFit.Cover).borderRadius(10)Row() {Image($r(app.media.ic_btn_close)).width(14).aspectRatio(1).fillColor(#ccc)}.width(30).aspectRatio(1).justifyContent(FlexAlign.Center).borderRadius(15).border({color: #ff343232,width: 2}).margin({top: 40}).onClick(() {if (ad.dialogName) {adManagerFinal.closeAd(ad.dialogName) // ? name从哪里进来}})}.width(ad.isFull ? 100% : 80%).height(ad.isFull ? 100% : 50%)
}export class AdManagerFinal {context?: Context// 所有的弹窗都放到这个map中 通过name来标识private map: Mapstring, ComponentContentAdvertClass new Map()// 实际上需要广告async showAd(ad: AdvertClass) {// 按照文档实现// UIContext上下文必须得等到页面初始化之后才可以进行获取// 生成一个namelet name dialog_${util.generateRandomUUID()}// 通过当前的主窗口来获取const mainWin await window.getLastWindow(this.context || getContext())let uiContext mainWin.getUIContext() // 拿到UIContextlet promptAction uiContext.getPromptAction();ad.dialogName name // 目的是将dialog的弹窗名称传递到builder中let contentNode new ComponentContent(uiContext, wrapBuilder(AdBuilder), ad);let options: promptAction.BaseDialogOptions {alignment: DialogAlignment.Center,autoCancel: false};this.map.set(name, contentNode) // 将key/value写入到map中promptAction.openCustomDialog(contentNode, options);// 一般半屏广告 是得用户手动点击才能关闭的 一般不会自动关闭// setTimeout(() {// promptAction.closeCustomDialog(contentNode)// }, 2000)}async closeAd(name: string) {if (name) {const mainWin await window.getLastWindow(this.context || getContext())let uiContext mainWin.getUIContext() // 拿到UIContextlet promptAction uiContext.getPromptAction();promptAction.closeCustomDialog(this.map.get(name))// 清理mapthis.map.delete(name) // 删除已经关闭的弹窗}}
}export const adManagerFinal new AdManagerFinal()
6.完整代码-EntryAbility async onWindowStageCreate(windowStage: window.WindowStage): Promisevoid {// Main window is created, set main page for this abilityhilog.info(0x0000, testTag, %{public}s, Ability onWindowStageCreate);// 开启全屏const win windowStage.getMainWindowSync()win.setWindowLayoutFullScreen(true)// 获取安全区域const top win.getWindowAvoidArea(window.AvoidAreaType.TYPE_SYSTEM).topRectAppStorage.setOrCreatenumber(safeTop, px2vp(top.height))const bottom win.getWindowAvoidArea(window.AvoidAreaType.TYPE_NAVIGATION_INDICATOR).bottomRectAppStorage.setOrCreatenumber(safeBottom, px2vp(bottom.height))windowStage.loadContent(pages/Index, (err) {if (err.code) {hilog.error(0x0000, testTag, Failed to load the content. Cause: %{public}s, JSON.stringify(err) ?? );return;}hilog.info(0x0000, testTag, Succeeded in loading the content.);getUser.initUser()auth.initUser()});//广告// 发起一个向云端获取广告数据的请求const userSetting new UserSetting(this.context)const result await new PromiseAdvertClass((resolve, reject) {setTimeout(() {resolve({showAd: true,adTime: 5,adImg: $r([basic].media.start)} as AdvertClass)}, 1000)})await userSetting.setUserAd(result) // 写入首选项if (result.showAd) {const win await windowStage.createSubWindow(ad_window)await win.showWindow()win.setUIContent(pages/StartPage)}}
