uniapp 实现tabbar图标凸起

实现tabbar图标凸起有两种，第一种是自定义tabbar，第二种就是使用官方的tabbar跟api实现，自定义在体验中不如原生的tabbar，所以我下面展示的是使用官方的tabbar跟api实现

效果如图：

左边是未选中中间的凸起，右边是选中中间凸起，有一个问题就是我们选中凸起后文字颜色没有改变，目前我还没找到解决方案，有办法的兄弟们可以留言

代码实现

tabbar

"tabBar": {"borderStyle": "white","backgroundColor": "white","color": "#8F8F94","selectedColor": "#e3b23e","list": [{"pagePath": "pages/xxxx/xxxx","iconPath": "static/uni.png","selectedIconPath": "static/uni.png","text": "主页"},{"pagePath": "pages/xxxx/xxxx","iconPath": "static/uni.png","selectedIconPath": "static/uni.png","text": "积分榜"},{"pagePath": "pages/xxxx/xxxx","iconPath": "static/c8.png","selectedIconPath": "static/uni.png","text": "订阅/下单","visible": false},{"pagePath": "pages/xxxx/xxxx","iconPath": "static/uni.png","selectedIconPath": "static/uni.png","text": "任务"},{"pagePath": "pages/xxxx/xxxx","iconPath": "static/uni.png","selectedIconPath": "static/uni.png","text": "我的账户"}],"midButton": {"iconPath": "static/c8.png","iconWidth": "60px","height": "80px","text": "订阅/下单"}}

midButton 中间按钮仅在 list 项为偶数时有效，官方说明：

pages.json 页面路由 | uni-app官网

监听点击中的tabbar，并修改图标为选中状态 app.vue中监听

// 点击中间按钮  uni.onTabBarMidButtonTap(() => {console.log('中间')uni.setTabBarStyle({midButton: {"iconPath": "static/uni.png","iconWidth": "60px","height": "80px","text": "订阅/下单","color": "red"}})uni.switchTab({url: '/pages/xxx/xxx'})})

然后在其他的tabbar list的页面监听tabbar点击，点击不是中间tabbar，为其他tabbar时将中间tabbar又改为未选中状态

javascript"><script>import {onTabItemTap} from "@dcloudio/uni-app"import {} from 'vue';export default {setup() {onTabItemTap((e) => {uni.setTabBarStyle({midButton: {"iconPath": "static/c8.png","iconWidth": "60px","height": "80px","text": "订阅/下单"}})})return {};}};
</script>
