小程序 map 地图 moveAlong 方法调动移动动画，小米手机动画有时不正常，报错：(in promise) MiniProgramError {"errMsg":"moveMapMarkerAlong:fail"}苹果手机和开发者工具中是正常的 参照这个文档写的demo https://developers.weixin.qq.com/miniprogram/dev/api/media/map/MapContext.moveAlong.html[图片] cont mapCtx = wx.createMapContext('myMap'); mapCtx.moveAlong({ markerId: 0, path: this.data.polyline[0].points, autoRotate: true, duration: 3000 });
