使用场景

该示例主要展示出行类app乘客端用户在设置起点和终点的方案。

用到产品

Android 地图 SDK 

接口

说明

版本

AMap

显示地图

V2.0.0版本起

PoiSearch

searchPOIAsyn()

查询POI异步接口

V2.1.0版本起

PoiSearch

setOnPoiSearchListener(PoiSearch.OnPoiSearchListener listener)

设置查询监听接口

V2.1.0版本起

Android 定位 SDK

核心类/接口

接口

说明

版本

AMapLocationClientOption

setOnceLocation(Boolean b);

设置单次定位接口

V2.0.0版本起

AMapLocationClientOption

setInterval(long time);

设置连续定位时间间隔

V2.0.0版本起

AMapLocationClient

startLocation();

启动定位

V2.0.0版本起

AMapLocationClient

setLocationOption(mLocationOption);

给定位客户端设置参数

V2.0.0版本起

AMapLocationListener

onLocationChanged(AMapLocation amapLocation);

监听器回调方法

V2.0.0版本起

核心难点

1、启动时通过定位SDK获取当前位置

采用定位SDK提供的高精度定位功能,定位前打开设备的wifi模块提升定位精度。


2、通过搜索获取位置

可参考示例中向高德POI搜索接口传参数的方式和内容。
