在第二关我们说了如何查询公交路线图，但前提你得知道公交是几路公交！而一般人知道某个地点，就想去，而不是通过几路公交来查询！所以这关我们来说说如果查询两个地点之间的路线规划【1.骑行路线2.驾车路线3.公交路线4.步行路线】

第一步【路线搜索类和监听】RoutePlanSearch|OnGetRoutePlanResultListener

和公交线路查询一样，直接用newInstance()得到对象 //路径规划搜索接口 routePlanSearch = RoutePlanSearch.newInstance(); routePlanSearch.setOnGetRoutePlanResultListener(this);

第二步【通过调用不同的方法进行查询】

/** * 2.各种路线规划的查询 */ case R.id.btn_search_biking: //骑行路线 routePlanSearch.bikingSearch(new BikingRoutePlanOption().from(fromPlanNode).to(toPlanNode)); layoutBusSearch.setVisibility(View.GONE); break; case R.id.btn_search_car: //驾车路线 routePlanSearch.drivingSearch(new DrivingRoutePlanOption().from(fromPlanNode).to(toPlanNode)); layoutBusSearch.setVisibility(View.GONE); break; case R.id.btn_search_bus: //换乘公共交通工具的路线 routePlanSearch.transitSearch(new TransitRoutePlanOption().city(etCity.getText().toString()).from(fromPlanNode).to(toPlanNode)); layoutBusSearch.setVisibility(View.GONE); break; case R.id.btn_search_walk: //步行路线 routePlanSearch.walkingSearch(new WalkingRoutePlanOption().from(fromPlanNode).to(toPlanNode)); layoutBusSearch.setVisibility(View.GONE); break;

第三部【得到不同的回到结果，并添加覆盖物到地图上】

a.首先初始化各种覆盖物 //公交路线覆盖物，并设置路线的点击事件 overlay = new BusLineOverlay(mBaiduMap); //骑行覆盖物添加并监听 bikingOverlay = new BikingRouteOverlay(mBaiduMap); //驾车覆盖物添加并监听 drivingOverlay= new DrivingRouteOverlay(mBaiduMap); //换乘覆盖物添加并监听 transOverlay = new TransitRouteOverlay(mBaiduMap); //步行覆盖物添加并监听 walkingOverlay = new WalkingRouteOverlay(mBaiduMap); //TODO: 添加各种路线覆盖物的点击事件 mBaiduMap.setOnMarkerClickListener(overlay); mBaiduMap.setOnMarkerClickListener(bikingOverlay); mBaiduMap.setOnMarkerClickListener(drivingOverlay); mBaiduMap.setOnMarkerClickListener(transOverlay); mBaiduMap.setOnMarkerClickListener(walkingOverlay); b.然后根据不同的回调，把覆盖物添加到地图上面 /** * 以下四个方法是路线规划搜索监听后的回调 * a.步行回调 * @param walkingRouteResult */ @Override public void onGetWalkingRouteResult(WalkingRouteResult walkingRouteResult) { if (walkingRouteResult == null || walkingRouteResult.error != SearchResult.ERRORNO.NO_ERROR) { T.showLong(this, "抱歉，未找到结果"); return; } L.i("线路条数：" + walkingRouteResult.getRouteLines().size()); List<WalkingRouteLine> routeLines = walkingRouteResult.getRouteLines(); mBaiduMap.clear(); walkingOverlay.removeFromMap(); walkingOverlay.setData(routeLines.get(0)); walkingOverlay.addToMap(); walkingOverlay.zoomToSpan(); } /** * b.换乘路线结果回调 * @param transitRouteResult */ @Override public void onGetTransitRouteResult(TransitRouteResult transitRouteResult) { if (transitRouteResult == null || transitRouteResult.error != SearchResult.ERRORNO.NO_ERROR) { T.showLong(this, "抱歉，未找到结果"); return; } L.i("线路条数：" + transitRouteResult.getRouteLines().size()); List<TransitRouteLine> routeLines = transitRouteResult.getRouteLines(); mBaiduMap.clear(); transOverlay.removeFromMap(); transOverlay.setData(routeLines.get(0)); transOverlay.addToMap(); transOverlay.zoomToSpan(); } /** * c.驾车路线结果回调 * * @param drivingRouteResult */ @Override public void onGetDrivingRouteResult(DrivingRouteResult drivingRouteResult) { if (drivingRouteResult == null || drivingRouteResult.error != SearchResult.ERRORNO.NO_ERROR) { T.showLong(this, "抱歉，未找到结果"); return; } L.i("线路条数：" + drivingRouteResult.getRouteLines().size()); List<DrivingRouteLine> routeLines = drivingRouteResult.getRouteLines(); mBaiduMap.clear(); drivingOverlay.removeFromMap(); drivingOverlay.setData(routeLines.get(0)); drivingOverlay.addToMap(); drivingOverlay.zoomToSpan(); } /** * d.骑行路线结果回调 * * @param bikingRouteResult */ @Override public void onGetBikingRouteResult(BikingRouteResult bikingRouteResult) { if (bikingRouteResult == null || bikingRouteResult.error != SearchResult.ERRORNO.NO_ERROR) { T.showLong(this, "抱歉，未找到结果"); return; } L.i("线路条数：" + bikingRouteResult.getRouteLines().size()); List<BikingRouteLine> routeLines = bikingRouteResult.getRouteLines(); mBaiduMap.clear(); bikingOverlay.removeFromMap(); bikingOverlay.setData(routeLines.get(0)); bikingOverlay.addToMap(); bikingOverlay.zoomToSpan(); } 总体代码BusLineMapActivity package cq.cake.chwl.ui; import android.os.Bundle; import android.view.Menu; import android.view.MenuItem; import android.view.View;
