Android百度地图——路线规划搜索（二）

百度地图的搜索模块，是可以去掉地图模块独立使用的。为了方便使用在《Android百度地图——路线规划搜索》这篇文章前提下再次封装成独立的类。

先来看一下封装后的调用方法：

        BaiduSearch search = new BaiduSearch(context);        search.setOnMyGetRoutePlanResultListener(new OnMyGetRoutePlanResultListener() {            @Override            public void onGetWalkingRouteResult(WalkingRouteResult arg0) {                // TODO Auto-generated method stub                //搜索结果可以自行解析，也可以直接在地图上加载，下面onGetDrivingRouteResult给出了地图加载例子            }            @Override            public void onGetTransitRouteResult(TransitRouteResult arg0) {                // TODO Auto-generated method stub                            }            @Override            public void onGetDrivingRouteResult(DrivingRouteResult arg0) {                // TODO Auto-generated method stub                DrivingRouteOverlay overlay = new MyDrivingRouteOverlay(mBaidumap);                overlay.setData(arg0.getRouteLines().get(0));                overlay.addToMap();                overlay.zoomToSpan();            }            @Override            public void onGetBikingRouteResult(BikingRouteResult arg0) {                // TODO Auto-generated method stub                            }        });        ArrayList pass=new ArrayList();        pass.add(new LatLng( 23.102603,113.304713));        search.SearchProcess(new LatLng( 23.159499,113.261269)                , new LatLng(23.15312,113.328859 )                , pass                , BaiduSearch.DrivingRoute);

下面是BaiduSearch.java的代码：
