在app.json中增加了：

“tabBar”: {

“position”:“bottom”,

“selectedColor”: “#2A8CEF”,

“borderStyle”: “white”,

“list”: [

{

“pagePath”: “pages/logs/logs”,

“text”: “进度”

},

{

“pagePath”: “pages/logs/logs”,

“text”: “回顾”

},

{

“pagePath”: “pages/logs/logs”,

“text”: “我的”

}

]

}

编译后，toolbar不能显示。新手，多体谅。
