1、Android集成百度地图接口,实现定位+路径规划。新手教程 本文主要内容包括:如何根据百度地图接口实现定位,并实现从A到B的路径规划功能(驾车,公交,步行)。本文主要提供给新手参考,如果有错误希望博友们指出以便及时改正。1.申请百度地图SDK的密钥(填写安全码是一定注意:Android SDK安全码组成：数字签名+;+包名)。2.在 下载示例代码。3.Eclipse中导入实例代码。4.在AndroidManifest.xml中 把申请的密钥填进去(如图).5.这样就可以运行我们刚刚下载的百度地图demo.我们下面要做的就是把demo里面能用的代码改成我们需要的功能:我们需要的功能就是:获取我

2、的位置,然后帮我导航到我想去的地方。(实际开发中可能是与服务器交互的任意位置)首先贴上我们的项目结构,文章结尾也会有代码下载地址(免积分下载)。1.我们需要下载百度地图API的示例代码与类参考。如下图所示。2.Eclipse导入百度地图BaiduLBS_AndroidSDK_Sample地图+检索+LBS云检索+工具 下的示例项目,大家可以按照本文开头的配置运行一下demo,本文就不在展示demo运行效果。3.由于我们这次需要的功能是线路规划,所以demo中我们需要的类是 RoutePlanDemo,二话不说新建项目先将这个Activity类粘贴进去。4.我们需要在我们自己的Applicati

3、on类中初始化百度SDK组件,所以我们再把demo中的 DemoApplication类粘贴到新建项目。而且我们需要在AndroidManifest中配置此类。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中将两个位置参数赋值给了PlanNode对象, 现在我们打开刚刚我们下载的类参考中的文档,路径如下:百度地图BaiduLBS_AndroidSDK_Docs地图+检索+LBS云检索+工具index.html找到PlanNode类,此类提供给我们两个方法如下图所示:7.所以我们只需要把我们的起点和终点

19、的位置信息(经纬度或者地名和城市名)放入方法的参数中即可.而现在我们需要的起点是根据我们实时的定位而决定的,所以现在我们还需要调用百度的定位方法,来获取我们的当前定位信息。8.要想获取我们当前所在位置,我们可以实现BDLocationListener接口,使用BDLocation类中的 getLatitude()与getLongitude方法,获取我们当前的位置。然后将获取到的经纬度放到下面的方法中即可。PlanNode stNode = PlanNode.withLocation(new LatLng(myLatitude, myLongitude);9.很简单,到此我们就实现了今天我们想实

20、现的所有功能,我们只需要一个activity类就可以完成我们的百度地图demo.代码如下:/* * 此demo用来展示如何进行驾车、步行、公交路线搜索并在地图使用RouteOverlay、TransitOverlay绘制 * 同时展示如何进行节点浏览并弹出泡泡 */public class RoutePlanDemo extends Activity implements BaiduMap.OnMapClickListener, OnGetRoutePlanResultListener /全局变量private double myLongitude; /经度private double myL

22、y = null; boolean useDefaultIcon = false; private TextView popupText = null;/泡泡view /地图相关，使用继承MapView的MyRouteMapView目的是重写touch事件实现泡泡处理 /如果不处理touch事件，则无需继承，直接使用MapView即可 MapView mMapView = null; / 地图View BaiduMap mBaidumap = null; /搜索相关 RoutePlanSearch mSearch = null; / 搜索模块，也可去掉地图模块独立使用 protected vo
