小程序项目有用到需要自定义地图的需求，于是记录下操作流程
1、引入高德地图sdk包 下载地址：https://lbs.amap.com/api/wx/download
2、项目中导入并初始化
//导入
import amapFile from '../../../utils/libs/amap-wx.js' //高德地图sdk
let myAmapFun
//初始化
componentWillMount = () => {
/// 初始化高德地图
myAmapFun = new amapFile.AMapWX({ key: ThirdPartKey.amapKey })
}
3、获取当前定位 并初始化气泡 并刷新地图底部poi商家显示
componentDidMount() {
/// 获取精准定位
let that = this
myAmapFun.getRegeo({
success: (data) => {
// markersData = data.markers;
console.log(data)
var {
latitude,
longitude
} = that.state
let { pois, addressComponent } = data[0].regeocodeData
latitude = data[0].latitude
longitude = data[0].longitude
let marker
if (pois.length > 0) {
marker = this.getMarker(pois[0])
/// 默认选中第0组数据
pois[0].checked = true
}
/// 加上省市区 让地址变得长一些
pois.map(item => {
item.realaddress = addressComponent.province + addressComponent.city + addressComponent.district + item.address
})
var markers: any = []
if (marker) {
markers.push(marker)
}
this.setState({ latitude, longitude, pois, markers })
},
fail: (err) => {
console.log(err)
}
})
}
3、点击搜索进入到键盘输入实时获取周边商家的页面
onInputValueChange = (e) => {
const { value } = e.detail
// console.log(value)
if (value.length == 0) {
this.setState({
searchResults: [],
// showSearch: false,
keyword: '',
}, () => {
// Taro.hideKeyboard()
});
return
}
/// 搜索POI功能
myAmapFun.getInputtips({
keywords: value,
// city: '杭州',
// location: '120.299221,30.419153',
success: (data) => {
console.log(data)
if (data && data.tips) {
this.setState({
keyword: value,
searchResults: data.tips
});
}
}
})
}
4、搜索结果点击后重新获取该点击定位的周边的POI并刷新显示
onResultItemClick = (item) => {
/// 根据搜索结果 重新定位
/// 将经纬度字符串转换出来
try {
let locations = item.location.split(',')
let longitude = locations[0]
let latitude = locations[1]
let marker = {
id: item.id,
latitude,
longitude,
name: item.name,
width: 20,
height: 30,
}
/// 根据经纬度 获取周边的poi
myAmapFun.getPoiAround({
location: item.location,
success: (data) => {
console.log(data)
let pois = data.poisData || []
if (pois.length > 0) {
pois[0].checked = true
}
pois.map(res => {
res.realaddress = res.pname + res.cityname + res.adname + res.address
})
this.setState({
keyword: '',
showSearch: false,
markers: [marker],
latitude, longitude,
searchResults: [],
pois
})
},
fail: (err) => {
this.setState({
keyword: '',
showSearch: false,
markers: [marker],
searchResults: [],
latitude, longitude
})
}
})
} catch (error) {
let e = {
detail: {
value: item.name,
}
}
this.onInputValueChange(e)
}
}
5、点击地图底部POI实时更新气泡角标
onPoiItemClick = (item: any, index: number) => {
/// 点击重新设置气泡
let marker = this.getMarker(item)
let { pois } = this.state
/// 清空所有的显示
pois.map(data => {
data.checked = false
return item
})
pois[index].checked = true
this.setState({
markers: [marker],
pois
})
}
