本篇文章可以實(shí)現(xiàn)百度公交線路搜索，可以選擇多條線路，具體實(shí)現(xiàn)代碼如下：
一、公交線路詳情檢索
獲取公交線路的詳情主要分來兩步，1.獲取公交線路的Uid，2.通過Uid獲取公交線路詳情。
1.獲取公交線路的Uid：
/* * 獲得公交線路圖的Uid，并且根據(jù)系Uid發(fā)起公交線路詳情的檢索 * * @see * com.baidu.mapapi.MKSearchListener#onGetPoiResult(com.baidu.mapapi * .MKPoiResult, int, int) */ @Override public void onGetPoiResult(MKPoiResult arg0, int arg1, int arg2) { // TODO Auto-generated method stub if (arg0 == null || arg2 != 0) { Toast.makeText(MainActivity.this, "未找到結(jié)果", 1); return; } // 定義一個公交線路描述類 MKPoiInfo mkPoiInfo = null; // 獲得本次就愛你所的公交線路的總站點(diǎn) int totalPoiNum = arg0.getNumPois(); for (int i = 0; i < totalPoiNum; i++) { mkPoiInfo = arg0.getPoi(i); if (mkPoiInfo.ePoiType == 2) { break; } } mkSearch.busLineSearch("開封", mkPoiInfo.uid); }2.獲取公交線路詳情：
/* * 得到公交線路圖的詳情 * * @see * com.baidu.mapapi.MKSearchListener#onGetBusDetailResult(com.baidu. * mapapi.MKBusLineResult, int) */ @Override public void onGetBusDetailResult(MKBusLineResult arg0, int arg1) { // TODO Auto-generated method stub if (arg0 == null || arg1 != 0) { Toast.makeText(MainActivity.this, "未找到結(jié)果", 1); return; } RouteOverlay routeOverlay = new RouteOverlay(MainActivity.this, mapView); routeOverlay.setData(arg0.getBusRoute());// 獲得公交線路 mapView.getOverlays().clear();// 清楚公交站點(diǎn)的標(biāo)識 mapView.getOverlays().add(routeOverlay); mapView.invalidate(); // 采用動畫形式描述公交站點(diǎn) mapView.getController().animateTo(arg0.getBusRoute().getStart()); }查詢時，只需提供城市名和線路
mkSearch.poiSearchInCity("開封", "3");完整代碼：

在同一個地圖上顯示多條導(dǎo)航線路，也只需要分兩步完成，
1.定義起始點(diǎn)個終點(diǎn)
start = new MKPlanNode(); start.pt = new GeoPoint((int) (39.915 * 1E6), (int) (116.404 * 1E6)); end = new MKPlanNode(); end.pt = new GeoPoint(40057031, 116307852); mkSearch.transitSearch("北京", start, end);2.將所有的線路詳情循環(huán)顯示在地圖上
@Override public void onGetTransitRouteResult(MKTransitRouteResult arg0, int arg1) { // TODO Auto-generated method stub if (arg0 == null) { return; } int planNum = arg0.getNumPlan();// 獲取所有的駕車路線 for (int i = 0; i < planNum; i++) { TransitOverlay overlay = new TransitOverlay(MainActivity.this, mapView); overlay.setData(arg0.getPlan(i)); mapView.getOverlays().add(overlay); } mapView.invalidate(); mapView.getController().animateTo(arg0.getStart().pt); }以上就是本文的全部內(nèi)容，希望對大家的學(xué)習(xí)有所幫助，也希望大家多多支持武林網(wǎng)。
