GIS的学习（三十三）osmdroid OSMBonusPack实现Route，Bubble

  使用开源项目OSMBonusPack实现线路和气泡的功能：

项目结构如下：

 

具体代码如下：

package com.osmbonus.simple;

import java.util.ArrayList;

import org.osmdroid.bonuspack.overlays.ExtendedOverlayItem;
import org.osmdroid.bonuspack.overlays.ItemizedOverlayWithBubble;
import org.osmdroid.bonuspack.routing.OSRMRoadManager;
import org.osmdroid.bonuspack.routing.Road;
import org.osmdroid.bonuspack.routing.RoadManager;
import org.osmdroid.bonuspack.routing.RoadNode;
import org.osmdroid.tileprovider.tilesource.TileSourceFactory;
import org.osmdroid.util.GeoPoint;
import org.osmdroid.views.MapController;
import org.osmdroid.views.MapView;
import org.osmdroid.views.overlay.OverlayItem;
import org.osmdroid.views.overlay.PathOverlay;

import android.app.Activity;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
/**
 * 备注：需要的注意事项：
 *   1.针对OSMBonusPack v2.x jars 是基于 osmdroid v3.0.8.  所以版本必须对应否则可能出现莫名其妙的问题。
 *   2.以下是集成必须的资源信息
 *      •For a white bubble: 
 *			◦drawable-mpi/bonuspack_bubble.9.png 
 *			◦layout/bonuspack_bubble.xml 
 *			•For a dark-grey bubble: 
 *			◦drawable-mpi/bonuspack_bubble_black.9.png 
 *			◦layout/bonuspack_bubble_black.xml 
 *		•For the "more info" button: 
 *			◦drawable/btn_moreinfo.xml 
 *			◦drawable-mpi/moreinfo_arrow.png 
 *			◦drawable-mpi/moreinfo_arrow_pressed.png 
 *   3.地图使用的权限总结：
 *          <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> 
 * 			<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
 * 			<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
 * 			<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
 * 			<uses-permission android:name="android.permission.INTERNET" />
 * 			<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
 *
 *针对OSMBonusPack中几个重要的特性：
 *   1.根据地点名称查询POI
 *   2.查询附近的POI
 *   3.根据起始点规划线路
 *   4.marker气泡重写和定制
 *   5.地图poi点的响应处理

RoadManager roadManager = new OSRMRoadManager();
LZ你好，你用这个生产路径的时候，没有遇到生成的路径只是直线的情况吗？没有路径上的node
log显示错误:OSRMRoadManager::getRoad: request failed
官网demo貌似也有这个错误

zhuangshuo 写道

楼主有没有尝试用源码，而不用jar包

最先采用的是源代码方式没有跟踪问题,后来通过重写代码和jar形式实现.
