百度地图多点连接，起终点标注

//根据经度纬度多点连接         
List<LatLng> points = new ArrayList<LatLng>();//经度纬度集合
        if(dataList != null && !dataList.isEmpty()){
            for(int i=0,size=dataList.size();i<size;i++){
                points.add(new LatLng(dataList.get(i).getLatitude(), dataList.get(i)
                        .getLongitude()));
            }
        }
        //构造对象
OverlayOptions ooPolyline = new PolylineOptions().width(10)
.color(0xAAFF0000).points(points);
//添加到地图
mBaiduMap.addOverlay(ooPolyline);


//地图上标注起终点
