鸿蒙完整项目-仿盒马App（一）首页静态页面

跟着鸿蒙小林博主，练习下项目~记录下首页的搭建,后续继续完善和整体项目完成会进行布局修改，先按照博主的跟做，后续在改

1.分为底部整体框架搭建
2.首页布局（顶部搜索、新人专享、金刚区（两个不同集合数据）、图片海报、三个分区、瀑布流列表）。组件单独写的

1. MainPages

@Entry
@Component/***首页*/
struct MainPages {@State isCheck_Index_One: boolean = true@State currentIndex: number = 0//底部ui@BuildertabBuilder(title: string, targetIndex: number, selectedImg: Resource, normalImg: Resource) {Column() {Image(this.currentIndex === targetIndex ? selectedImg : normalImg).width(this.isCheck_Index_One && targetIndex === 0 ? 50 : 25).height(this.isCheck_Index_One && targetIndex === 0 ? 50 : 25).borderRadius(this.isCheck_Index_One && targetIndex === 0 ? 25 : 0)Text(title).margin({ top: 5 }).fontSize(14).margin({ top: 5 }).fontWeight(this.currentIndex === targetIndex ? FontWeight.Bold : FontWeight.Normal).fontColor('#6B6B6B')}.width('100%').height(50).justifyContent(FlexAlign.Center)}build() {//底部导航栏Column() {Tabs({ barPosition: BarPosition.End }) {TabContent() {//首页布局HomeUI()}.tabBar(this.tabBuilder("首页", 0, $r('app.media.me_image'), $r('app.media.index1_not_check')))TabContent() {Text('分类').fontSize(30)}.tabBar(this.tabBuilder("分类", 1, $r('app.media.index2_check'), $r('app.media.index2_not_check')))TabContent() {Text('购物车').fontSize(30)}.tabBar(this.tabBuilder("购物车", 2, $r('app.media.index3_check'), $r('app.media.index3_not_check')))TabContent() {Text('我的').fontSize(30)}.tabBar(this.tabBuilder("我的", 3, $r('app.media.index4_check'), $r('app.media.index4_not_check')))}.onChange((index: number) => {this.currentIndex = indexif (index === 0) {this.isCheck_Index_One = true} else {this.isCheck_Index_One = false}})}.linearGradient({angle: 180,colors: [[0xff0000, 0], [0xff6666, 0.2], [0xffffff, 1]]}).width('100%').height('100%')}
}

2. HomeUI
