wxml:

<map id="map" longitude="{{longitude}}" latitude="{{latitude}}"

include-points="{{includepoints}}"

 scale="{{scale}}" markers="{{markers}}" 

  polyline="{{polyline}}" show-location

  style="width: 100%; height: {{view.Height}}px;"></map>

赋值逻辑代码：

  latitude: (23.429669+res.latitude)/2,

  longitude: (113.236140+res.longitude)/2,

  includepoints:{points:[{latitude:23.429669,longitude:113.236140},{latitude:res.latitude,longitude:res.longitude}],padding:[ 70,]},

视野并不会自动缩放
