KC10880106-i02Android集成百度地圖接口,實現(xiàn)定位+路徑規(guī)劃

1、Android集成百度地圖接口,實現(xiàn)定位+路徑規(guī)劃。新手教程 本文主要內容包括:如何根據(jù)百度地圖接口實現(xiàn)定位,并實現(xiàn)從A到B的路徑規(guī)劃功能(駕車,公交,步行)。本文主要提供給新手參考,如果有錯誤希望博友們指出以便及時改正。1.申請百度地圖SDK的密鑰(填寫安全碼是一定注意:Android SDK安全碼組成：數(shù)字簽名+;+包名)。2.在 下載示例代碼。3.Eclipse中導入實例代碼。4.在AndroidManifest.xml中 把申請的密鑰填進去(如圖).5.這樣就可以運行我們剛剛下載的百度地圖demo.我們下面要做的就是把demo里面能用的代碼改成我們需要的功能:我們需要的功能就是:獲取我

2、的位置,然后幫我導航到我想去的地方。(實際開發(fā)中可能是與服務器交互的任意位置)首先貼上我們的項目結構,文章結尾也會有代碼下載地址(免積分下載)。1.我們需要下載百度地圖API的示例代碼與類參考。如下圖所示。2.Eclipse導入百度地圖BaiduLBS_AndroidSDK_Sample地圖+檢索+LBS云檢索+工具 下的示例項目,大家可以按照本文開頭的配置運行一下demo,本文就不在展示demo運行效果。3.由于我們這次需要的功能是線路規(guī)劃,所以demo中我們需要的類是 RoutePlanDemo,二話不說新建項目先將這個Activity類粘貼進去。4.我們需要在我們自己的Applicati

3、on類中初始化百度SDK組件,所以我們再把demo中的 DemoApplication類粘貼到新建項目。而且我們需要在AndroidManifest中配置此類。配置文件如下。<span style="font-family:Times New Roman;"><manifest xmlns:android=" package="com.example.mybaidumap" android:versionCode="1" android:versionName="1.0" > &l

18、quot;北京", editSt.getText().toString(); PlanNode enNode = PlanNode.withCityNameAndPlaceName("北京", editEn.getText().toString();6.可以看出demo中將兩個位置參數(shù)賦值給了PlanNode對象, 現(xiàn)在我們打開剛剛我們下載的類參考中的文檔,路徑如下:百度地圖BaiduLBS_AndroidSDK_Docs地圖+檢索+LBS云檢索+工具index.html找到PlanNode類,此類提供給我們兩個方法如下圖所示:7.所以我們只需要把我們的起點和終點

19、的位置信息(經緯度或者地名和城市名)放入方法的參數(shù)中即可.而現(xiàn)在我們需要的起點是根據(jù)我們實時的定位而決定的,所以現(xiàn)在我們還需要調用百度的定位方法,來獲取我們的當前定位信息。8.要想獲取我們當前所在位置,我們可以實現(xiàn)BDLocationListener接口,使用BDLocation類中的 getLatitude()與getLongitude方法,獲取我們當前的位置。然后將獲取到的經緯度放到下面的方法中即可。PlanNode stNode = PlanNode.withLocation(new LatLng(myLatitude, myLongitude);9.很簡單,到此我們就實現(xiàn)了今天我們想實

20、現(xiàn)的所有功能,我們只需要一個activity類就可以完成我們的百度地圖demo.代碼如下:/* * 此demo用來展示如何進行駕車、步行、公交路線搜索并在地圖使用RouteOverlay、TransitOverlay繪制 * 同時展示如何進行節(jié)點瀏覽并彈出泡泡 */public class RoutePlanDemo extends Activity implements BaiduMap.OnMapClickListener, OnGetRoutePlanResultListener /全局變量private double myLongitude; /經度private double myL
