通过给定一个经纬度，获取附近的地理位置信息（附近地址）

1.首先初始化地图

     private var aMap: AMap? = nulloverride fun initView() {//初始化地图aMap = mapView.map//初始化定位蓝点val myLocationStyle = MyLocationStyle() //初始化定位蓝点样式类myLocationStyle.myLocationType(MyLocationStyle.LOCATION_TYPE_SHOW) //只定位一次myLocationStyle.interval(2000) //设置连续定位模式下的定位间隔，只在连续定位模式下生效，单次定位模式下不会生效。单位为毫秒。myLocationStyle.showMyLocation(true) //控制是否显示定位蓝点aMap?.mapType = AMap.MAP_TYPE_NORMAL // 卫星地图模式aMap?.myLocationStyle = myLocationStyle//设置定位蓝点的StyleaMap?.uiSettings?.isMyLocationButtonEnabled = true //设置默认定位按钮是否显示，非必需设置。aMap?.isMyLocationEnabled = true // 设置为true表示启动显示定位蓝点，false表示隐藏定位蓝点并不进行定位，默认是false。//路线规划监听mRouteSearch = RouteSearch(this)mRouteSearch?.setRouteSearchListener(this)aMap?.setOnMyLocationChangeListener {//定位成功移动相机aMap?.animateCamera(CameraUpdateFactory.newLatLngZoom(LatLng(it.latitude, it.longitude), 15f))}aMap?.setOnMapLoadedListener { addMarkerInScreenCenter() }//移动地图，中心点地理编码查询geoCoderSearch = GeocodeSearch(this)geoCoderSearch?.setOnGeocodeSearchListener(this)//地图选点aMap?.setOnCameraChangeListener(object : AMap.OnCameraChangeListener {override fun onCameraChange(cameraPosition: CameraPosition) {}override fun onCameraChangeFinish(cameraPosition: CameraPosition) {if (!isMoveNearby) {mCenterLatLng = LatLonPoint(cameraPosition.target.latitude, cameraPosition.target.longitude)if (mCenterLatLng != null) {// 第一个参数表示一个LatLng，第二参数表示范围多少米，第三个参数表示是火系坐标系还是GPS原生坐标系val query = RegeocodeQuery(mCenterLatLng, 150f, GeocodeSearch.AMAP)//汽车维修|汽车服务相关|汽车销售|购物相关商务写字楼|住宅小区|培训机构|学校|知名企业|购物中心|综合酒楼|公园|地铁站|银行相关|标志性建筑物|体育休闲服务场所|餐饮相关场所|医疗保健相关
//                        query.poiType = "030000|010000|020000|060000|120201|120302|141400|141200|170100|060101|050101|110101|150500|160200|190600|080000|050000|090000"//开启查询地理编码geoCoderSearch?.getFromLocationAsyn(query)}startJumpAnimation()} else {isMoveNearby = false}}})}

2.查询地理编码回调，回调成功后通过PoiSearch查询附近地址信息

    //地理编码响应override fun onRegeocodeSearched(regeocodeResult: RegeocodeResult, p1: Int) {aMap?.cameraPosition?.zoom?.let {if (it > 18) {//附近地址poi查询val mPoiQuery = PoiSearch.Query("", "", regeocodeResult.regeocodeAddress.cityCode)mPoiQuery.pageSize = 10mPoiQuery.pageNum = 0val poiSearch = PoiSearch(this, mPoiQuery)poiSearch.setOnPoiSearchListener(this)//设置数据返回的监听器 (5)//设置周边搜索的中心点以及区域poiSearch.bound = PoiSearch.SearchBound(regeocodeResult.regeocodeQuery.point, 80, true)poiSearch.searchPOIAsyn()//开始搜索}}start_local.text = regeocodeResult.regeocodeAddress.formatAddressmStartPoint = regeocodeResult.regeocodeQuery.point}

3.周边搜索区域的回调（附近地址列表）

//附近地址poi查询回调
override fun onPoiSearched(result: PoiResult?, code: Int) {if (code == 1000) {result?.let {if (it.pois[0].distance < 30) {//移动到最近的点aMap?.animateCamera(CameraUpdateFactory.newLatLngZoom(LatLng(it.pois[0].latLonPoint.latitude, it.pois[0].latLonPoint.longitude), 19f))isMoveNearby = truestart_local.text = it.pois[0].titlemStartPoint = it.pois[0].latLonPointreturn}}}
}
