微信小程序开发之tabbar图标和颜色的实现

前期准备 ：注册，填材料，验证等等：https://mp.weixin.qq.com

1.浏览一遍简易教程，下载相应的开发工具

写一个小例子

点击左侧的 “编辑”-》点击右侧代码里的 app.json 修改为

{
 "pages":[
 "pages/fightings/home", 
 "pages/publish/home", 
 "pages/mine/home"
 ],
 "tabBar": {
 "list": [
 {
 "pagePath": "pages/fightings/home",
 "text": "挑战"
 },
 {
 "pagePath": "pages/publish/home",
 "text": "发布"
 },
 {
 "pagePath": "pages/mine/home",
 "text": "我"
 }
 ]
 },
 "window":{
 "backgroundTextStyle":"light",
 "navigationBarBackgroundColor": "#fff",
 "navigationBarTitleText": "i挑战",
 "navigationBarTextStyle":"black"
 }
}

说明

这个样子太丑了 我们先来美化一下这个tab

{
 "pages":[
 "pages/home/home", 
 "pages/fightings/home", 
 "pages/mine/home"
 ],
 "tabBar": {
 "color":"#666666",
 "selectedColor":"#f10b2e",

 "list": [
 {
 "pagePath": "pages/home/home",
 "text": "大厅",
 "iconPath": "./res/icon_tab_home.png",
 "selectedIconPath": "./res/icon_tab_home_hl.png"
 },
 {
 "pagePath": "pages/fightings/home",
 "text": "挑战",
 "iconPath":"./res/icon_tab_fighting.png",
 "selectedIconPath":"./res/icon_tab_fighting_hl.png"
 },

 {
 "pagePath": "pages/mine/home",
 "text": "我",
 "iconPath": "./res/icon_tab_me.png",
 "selectedIconPath": "./res/icon_tab_me_hl.png"
 }
 ]
 },
 "window":{
 "backgroundTextStyle":"light",
 "navigationBarBackgroundColor": "#fff",
 "navigationBarTitleText": "i挑战",
 "navigationBarTextStyle":"black"
 }
}

说明

字段都比较简单就不详细说了 其中 “iconPath”: “./res/icon_tab_me.png”是图片的路径

自己在项目里创建一个res文件夹，然后放入需要的图片

tab 好看一点了吧
