Android 高德的路线规划一个小坑

最近用到了高德地图的路线规划。。这个时候。。
4000
发现了个小问题。就是，起点和终点之间的距离过长时，骑行的路线规划，，就会很长时间，甚至规划不出来。。。

造成这个问题的原因就是之间的距离过长了，，用骑行的路线规划不合适，我也没仔细找这个距离具体是多少。。。如果遇到这个问题，你可以先计算下两点之间的距离。，然后如果大于一个距离，就把路线规划换成驾车的路线规划。

LatLng latLng=new LatLng(mStartPoint.getLatitude(),mStartPoint.getLongitude());
LatLng latLng1=new LatLng(mEndPoint.getLatitude(),mEndPoint.getLongitude());
float v = AMapUtils.calculateLineDistance(latLng, latLng1);
Log.e("zmm","距离-->"+v);
if(v>3000){
curType=1;
searchRouteResult(RouteSearch.DrivingDefault,TYPE_DRIVE);
}else{
curType=1;
searchRouteResult(RouteSearch.RidingDefault,TYPE_RIDE);
}

/**
* 开始搜索路径规划方案
*/
public void searchRouteResult(int mode,int type) {
Log.e("zmm","searchRouteResult");
if (mStartPoint == null) {
ToastUtil.show(GaoMipActivity.this, "定位中，稍后再试...");
return;
}
if (mEndPoint == null) {
ToastUtil.show(GaoMipActivity.this, "终点未设置");
}
final RouteSearch.FromAndTo fromAndTo = new RouteSearch.FromAndTo(mStartPoint, mEndPoint);

if(type==TYPE_DRIVE){
RouteSearch.DriveRouteQuery query = new RouteSearch.DriveRouteQuery(fromAndTo, mode, null, null, "");
mRouteSearch.calculateDriveRouteAsyn(query);
}else{
RouteSearch.RideRouteQuery query1 = new RouteSearch.RideRouteQuery(fromAndTo, mode);
mRouteSearch.calculateRideRouteAsyn(query1);// 异步路径规划骑行模式查询
}
}

如果就算是长距离的也想用骑行的路线规划。。我们可以稍微伪装下，当然，这个时候算出来的时间是不对的，因为用的是驾驶的速度来算的时间，你可以在驾驶的回调里面，把驾驶的速度修改下，就可以了。。。

写的有不妥的地方，望见谅。。。

最后：每日一语录：

只要路是对的，就不要害怕它是短暂还是遥远，你终究会到达。。。
