效果

我的页面实现

从UI效果上可以看出是头部的背景+头像和下面的业务item，因此整体可以使用RelativeContainer布局，业务item可以用column实现。

1、UI界面实现

build() {RelativeContainer() {Image($r('app.media.ic_background_mine')).width('100%').height(240).id('imageBg').alignRules({top: { anchor: '__container__', align: VerticalAlign.Top },middle: { anchor: '__container__', align: HorizontalAlign.Center }})CircleImageView({src: $r("app.media.ic_icon"), //本地图片资源radius: 60,border_Width: 1,border_Color: Color.Pink,}).id('imageIcon').margin({ top: 50 }).alignRules({top: { anchor: '__container__', align: VerticalAlign.Top },middle: { anchor: '__container__', align: HorizontalAlign.Center }})Text(decodeURIComponent(this.userName)).fontSize(20).fontColor(Color.Black).fontWeight(FontWeight.Bold).id('textUsername').margin({ top: 20 }).alignRules({top: { anchor: 'imageIcon', align: VerticalAlign.Bottom },middle: { anchor: '__container__', align: HorizontalAlign.Center }})Column() {Row() {Text('我的收藏').fontColor(Color.Black).margin({ left: 15 })Image($r("app.media.ic_mine_next")).width(25).height(22).margin({ right: 15 })}.justifyContent(FlexAlign.SpaceBetween).width('100%').height(50).margin({ top: 10 }).borderRadius(10).backgroundColor('#66CCCCCC').onClick(() => {if (this.isLogin) {router.pushUrl({ url: 'pages/mine/MineCollectPage' })} else {router.pushUrl({url: 'pages/LoginPage',params: {hideJump: true}})}})Row() {Text('个人积分').fontColor(Color.Black).margin({ left: 15 })Image($r("app.media.ic_mine_next")).width(25).height(22).margin({ right: 15 })}.justifyContent(FlexAlign.SpaceBetween).width('100%').height(50).margin({ top: 20 }).borderRadius(10).backgroundColor('#66CCCCCC').onClick(() => {if (this.isLogin) {router.pushUrl({ url: 'pages/mine/MineIntegralPage' })} else {router.pushUrl({url: 'pages/LoginPage',params: {hideJump: true}})}})Row() {Text('关于我们').fontColor(Color.Black).margin({ left: 15 })Image($r("app.media.ic_mine_next")).width(25).height(22).margin({ right: 15 })}.justifyContent(FlexAlign.SpaceBetween).width('100%').height(50).margin({ top: 20 }).borderRadius(10).backgroundColor('#66CCCCCC').onClick(() => {router.pushUrl({ url: 'pages/mine/MineAboutPage' })})Row() {Text('退出登录').fontColor(Color.Black).margin({ left: 15 })Image($r("app.media.ic_mine_next")).width(25).height(22).margin({ right: 15 })}.justifyContent(FlexAlign.SpaceBetween).width('100%').height(50).margin({ top: 20 }).borderRadius(10).backgroundColor('#66CCCCCC').visibility(this.isLogin ? Visibility.Visible : Visibility.None).onClick(() => {this.dialogController.open()})}.id('columnSetting').padding({ left: 10, right: 10 }).alignRules({top: { anchor: 'imageBg', align: VerticalAlign.Bottom },middle: { anchor: '__container__', align: HorizontalAlign.Center }}).width('100%')}.backgroundColor(Color.White).width('100%').height('100%')
}

2、退出登录弹窗

private dialogController = new CustomDialogController({builder: LoginOutDialog({ onLoginOut: () => {this.onLoginOut()} }),customStyle: true,alignment: DialogAlignment.Center,
})

3、执行退出登录请求

private onLoginOut() {HttpManager.getInstance().request<LoginOutBean>({method: RequestMethod.GET,url: 'https://www.wanandroid.com/user/logout/json' //wanAndroid的API：Banner}).then((result: LoginOutBean) => {LogUtils.info(TAG, "result: " + JSON.stringify(result))if (result.errorCode == 0) {this.clearUserData()//跳转到登录界面router.replaceUrl({ url: 'pages/LoginPage' })}}).catch((error) => {LogUtils.info(TAG, "error: " + JSON.stringify(error))})
}

4、清除用户数据

private clearUserData() {AppStorage.Set(Constants.APPSTORAGE_USERNAME, '')AppStorage.Set(Constants.APPSTORAGE_PASSWORD, '')AppStorage.Set(Constants.APPSTORAGE_ISLOGIN, false)
}

我的收藏

1、获取收藏数据

private getCollectData() {HttpManager.getInstance().request<CollectBean>({method: RequestMethod.GET,header: { "Cookie": `loginUserName=${this.userName}; token_pass=${this.token_pass}` },url: `https://www.wanandroid.com/lg/collect/list/${this.pageNum}/json` //wanAndroid的API：积分排行}).then((result: CollectBean) => {LogUtils.info(TAG, "getCollectData  result: " + JSON.stringify(result))if (this.isRefresh) {this.controller.finishRefresh()} else {this.controller.finishLoadMore()}if (result.errorCode == 0) {if (this.isRefresh) {this.collectListData = result.data.datas} else {if (result.data.datas.length > 0) {this.collectListData = this.collectListData.concat(result.data.datas)} else {promptAction.showToast({ message: '没有更多数据啦！' })}}}this.dialogController.close()}).catch((error) => {LogUtils.info(TAG, "error: " + JSON.stringify(error))if (this.isRefresh) {this.controller.finishRefresh()} else {this.controller.finishLoadMore()}this.dialogController.close()})
}

2、UI界面实现

build() {Column() {AppTitleBar({ title: "我的收藏" })RefreshListView({list: this.collectListData,controller: this.controller,isEnableLog: true,paddingRefresh: { left: 10, right: 10, top: 5, bottom: 5 },refreshLayout: (item: CollectItemBean, index: number): void => this.itemLayout(item, index),onItemClick: (item: CollectItemBean, index: number) => {LogUtils.info(TAG, "点击了：index： " + index + " item: " + item)router.pushUrl({url: 'pages/WebPage',params: {title: item.title,uriLink: this.isValidUrl(item.link) ? item.link : 'https://www.wanandroid.com/' + item.link  //规避部分情况下偶现link链接不完整}}, router.RouterMode.Single)},onRefresh: () => {//下拉刷新this.isRefresh = truethis.pageNum = 0this.getCollectData()},onLoadMore: () => {//上拉加载this.isRefresh = falsethis.pageNum++this.getCollectData()}}).flexShrink(1)}.width('100%').height('100%').backgroundColor('#F1F3F5')}@BuilderitemLayout(item: CollectItemBean, index: number) {RelativeContainer() {//标题Text(HtmlUtils.formatStr(item.title)).fontColor('#333333').fontWeight(FontWeight.Bold).maxLines(2).textOverflow({overflow: TextOverflow.Ellipsis}).fontSize(20).id("textTitle").alignRules({top: { anchor: 'textAuthor', align: VerticalAlign.Bottom },left: { anchor: '__container__', align: HorizontalAlign.Start }})//更新时间Text("作者：" + item.author /*+ "\t分类：" + item.chapterName*/ + "\t\t收藏时间：" + item.niceDate).fontColor('#666666').fontSize(14).id("textNiceDate").alignRules({bottom: { anchor: '__container__', align: VerticalAlign.Bottom },left: { anchor: '__container__', align: HorizontalAlign.Start }})}.width('100%').height(90).padding(10).borderRadius(10).backgroundColor(Color.White)}

个人积分

1、获取积分数据

private getIntegralData() {HttpManager.getInstance().request<IntegralBean>({method: RequestMethod.GET,header: { "Cookie": `loginUserName=${this.userName}; token_pass=${this.token_pass}` },url: `https://www.wanandroid.com/lg/coin/userinfo/json` //wanAndroid的API：积分排行}).then((result: IntegralBean) => {this.IntegralDataState = trueLogUtils.info(TAG, "getIntegralData  result: " + JSON.stringify(result))if (result.errorCode == 0) {this.userIntegralData = result.data}LogUtils.info(TAG, "IntegralDataState: " + this.IntegralDataState + "  LeaderboardDataState: " + this.LeaderboardDataState)if (this.IntegralDataState && this.LeaderboardDataState) {this.dialogController.close()}}).catch((error) => {this.IntegralDataState = trueLogUtils.info(TAG, "error: " + JSON.stringify(error))LogUtils.info(TAG, "IntegralDataState: " + this.IntegralDataState + "  LeaderboardDataState: " + this.LeaderboardDataState)if (this.IntegralDataState && this.LeaderboardDataState) {this.dialogController.close()}})
}//积分排行
private getLeaderboardData() {HttpManager.getInstance().request<LeaderboardBean>({method: RequestMethod.GET,header: {"Content-Type": "application/json"},url: `https://www.wanandroid.com/coin/rank/1/json` //wanAndroid的API：积分排行}).then((result: LeaderboardBean) => {this.LeaderboardDataState = trueLogUtils.info(TAG, "getLeaderboardData  result: " + JSON.stringify(result))if (result.errorCode == 0) {this.leaderboardListData = result.data.datas}LogUtils.info(TAG, "IntegralDataState: " + this.IntegralDataState + "  LeaderboardDataState: " + this.LeaderboardDataState)if (this.IntegralDataState && this.LeaderboardDataState) {this.dialogController.close()}}).catch((error) => {this.LeaderboardDataState = trueLogUtils.info(TAG, "error: " + JSON.stringify(error))LogUtils.info(TAG, "IntegralDataState: " + this.IntegralDataState + "  LeaderboardDataState: " + this.LeaderboardDataState)if (this.IntegralDataState && this.LeaderboardDataState) {this.dialogController.close()}})
}

2、UI界面实现

build() {Column() {AppTitleBar({ title: '个人积分' })Row() {Text('个人积分信息').fontSize(20).fontWeight(FontWeight.Bold)Text('积分获取列表 >>').fontSize(14).fontColor('#66666666').fontWeight(FontWeight.Bold).onClick(() => {router.pushUrl({ url: 'pages/mine/PointAcquisitionPage' })})}.width('100%').justifyContent(FlexAlign.SpaceBetween).height(50).padding({ left: 15, right: 15 }).backgroundColor('#66CCCCCC')Stack() {Column() {Text(decodeURIComponent(this.userName)).fontColor(Color.Black).fontSize(28).margin({ top: 5, bottom: 5 }).fontWeight(FontWeight.Bold)Text('积分：' + this.userIntegralData.coinCount).fontColor(Color.Red).margin({ top: 10, bottom: 10 }).fontSize(20)Text('等级：' + this.userIntegralData.level).fontColor(Color.Green).margin({ top: 10, bottom: 10 }).fontSize(20)Text('排名：' + this.userIntegralData.rank).fontColor('#1296db').margin({ top: 10, bottom: 10 }).fontSize(20)}.alignItems(HorizontalAlign.Start).padding(10).borderRadius(10).backgroundColor('#F1F3F5').width('100%')}.width('100%').padding({ left: 10, right: 10, top: 15, bottom: 15 })//积分排行榜Row() {Text('积分排行榜').fontSize(20).fontWeight(FontWeight.Bold)Text('更多信息 >>').fontSize(14).fontColor('#66666666').fontWeight(FontWeight.Bold).onClick(() => {router.pushUrl({ url: 'pages/mine/LeaderboardPage' })})}.width('100%').justifyContent(FlexAlign.SpaceBetween).height(50).padding({ left: 15, right: 15 }).backgroundColor('#66CCCCCC')if (this.leaderboardListData.length > 3) {LeaderboardItemLayout({ item: this.leaderboardListData[0] }).padding(10)LeaderboardItemLayout({ item: this.leaderboardListData[1] }).padding(10)LeaderboardItemLayout({ item: this.leaderboardListData[2] }).padding(10)}}.width('100%').height('100%')
}

3、效果

关于我们界面实现

1、效果

2、原理分析

要实现‘关于我们’文字和背景图片随着手指滑动而变化的效果。监听最外层布局的滑动事件，然后动态设置绝对偏移量（通过position方法实现）。

图片设置绝对偏移量

Image($r('app.media.ic_background_mine')).width('100%').height(this.imageHeight).position({ x: 0, y: this.offsetY - this.pullMaxHeight })

‘关于我们’文字根据滑动距离动态设置大小

Text('关于我们').fontColor(Color.White).fontSize(this.fontSize).position({ x: this.textInitialX, y: this.textInitialY + this.textPositionY })

底部内容设置绝对偏移量

Column() {//......}.padding(10).position({ y: this.imageHeight + this.offsetY - this.pullMaxHeight })
