在Android开发过程中大家可能会遇到这样的需求，根据两个位置的坐标计算行驶距离和时间，如下图

那这里改怎么实现呢？小编也是各种百度，最后发现高德地图自带了计算的API

1. 引用高德搜索包，在app目录下

//搜索功能
    implementation 'com.amap.api:search:latest.integration'

2. 实例化 DistanceSearch distanceSearch;
   DistanceSearch.DistanceQuery distanceQuery;

distanceQuery = new DistanceSearch.DistanceQuery();
        distanceSearch = new DistanceSearch(this);

3. 设置起点，终点经纬度继承DistanceSearch.OnDistanceSearchListener的回调

 LatLonPoint start = new LatLonPoint(Double.valueOf(start_lat), Double.valueOf(start_lng));
        LatLonPoint dest = new LatLonPoint(Double.valueOf(lat), Double.valueOf(lng));

        List<LatLonPoint> latLonPoints = new ArrayList<LatLonPoint>();
        latLonPoints.add(start);
        distanceQuery.setOrigins(latLonPoints);
        distanceQuery.setDestination(dest);
//        设置测量方式，支持直线和驾车
        distanceQuery.setType(DistanceSearch.TYPE_DRIVING_DISTANCE);
        distanceSearch.calculateRouteDistanceAsyn(distanceQuery);
        distanceSearch.setDistanceSearchListener(this);

4. DistanceSearch.OnDistanceSearchListener返回的DistanceResult返回信息就是我们要的数据，DistanceResult返回的是单位是米和秒，我们把单位转换一下

@Override
    public void onDistanceSearched(DistanceResult distanceResult, int i) {
        mStatusView.showContentView();
//        Log.d("距离", "onDistanceSearched: " + i);
        if (i == 1000) {
            String time_string;
            //距离米
            String distance = Integer.valueOf((int) distanceResult.getDistanceResults().get(0).getDistance()) / 1000 + "";
            //时间秒 转分钟
            /*int time = (int) distanceResult.getDistanceResults().get(0).getDuration() / 60;
            Log.d("距离", "onDistanceSearched: " + distance + "   " + time);
            int hours = (int) Math.floor(time / 60);
            int minute = time % 60;
            if (hours > 0) {
                time_string = time + "小时" + minute + "分钟";
            } else {
                time_string = minute + "分钟";
            }*/

            long second = (long) distanceResult.getDistanceResults().get(0).getDuration();

            long days = second / 86400;            //转换天数
            second = second % 86400;            //剩余秒数
            long hours = second / 3600;            //转换小时
            second = second % 3600;                //剩余秒数
            long minutes = second / 60;            //转换分钟
            second = second % 60;

            if (days > 0) {
                time_string = days + "天" + hours + "小时" + minutes + "分钟";
            } else if (hours > 0) {
                time_string = hours + "小时" + minutes + "分钟";
            } else {
                time_string = minutes + "分钟";
            }
            mTvDistance.setText("距您约" + distance + "公里，驾车约" + time_string);

        } else {
            mTvDistance.setText("暂无定位信息");
        }

    }

至此大功告成，就成功的拿到驾车行驶距离和时间！
