测量地图上的距离
页面发布时测量地图的距离时怎么做的啊
liwei007 ：
MapJ myMap = new MapJ();
DoublePoint firstPoint = new DoublePoint(第一个点的x坐标，第一个点的y坐标);
DoublePoint secondPoint = new DoublePoint(第二个点的x坐标, 第二个点的y坐标);
firstPoint = myMap.transformScreenToNumeric(firstPoint);
secondPoint = myMap.transformScreenToNumeric(secondPoint);
double distance = myMap.sphericalDistance(firstPoint,secondPoint); |
