页面不显示内容的问题

老师，我在index页面，寄快递，查快递，和我的页面里面都写了<view>hello world</view> 但是只有index页面显示了，切换到其他页面都没有显示。控制台也没有报错。这是为什么呢？
以下是我的app.json配置

{
  "pages":[
    "pages/index/index",
    "pages/send/send",
    "pages/search/search",
    "pages/my/my" 
  ],
  "window":{
    "backgroundTextStyle":"light",
    "navigationBarBackgroundColor": "#35BD00",
    "navigationBarTextStyle":"white"
  },
  "tabBar": {
    "color": "#666666",
    "selectedColor": "#35BD00",
    "list":[{
      "pagePath": "pages/index/index",
      "iconPath": "resources/home-icon.png",
      "selectedIconPath": "resources/home-icon-hover.png",
      "text": "首页"
    },{
      "pagePath": "pages/send/send",
      "iconPath": "resources/send-icon.png",
      "selectedIconPath": "resources/send-icon-hover.png",
      "text": "寄快递"
    },{
      "pagePath": "pages/search/search",
      "iconPath": "resources/polling-icon.png",
      "selectedIconPath": "resources/polling-icon-hover.png",
      "text": "查快递"
    },{
      "pagePath": "pages/my/my",
      "iconPath": "resources/my-icon.png",
      "selectedIconPath": "resources/my-icon-hover.png",
      "text": "我的"
    }]
  },
  "style": "v2",
  "sitemapLocation": "sitemap.json"
}
