2016一路有你，2017一起奋斗！
最近共享单车很火，动辄几亿美刀，屌丝的我只有羡慕的份。啥时候自己也能创一番事业呢？我眉头紧皱深深地思索着。个人认为LBS是移动互联网最主要的特征之一，自己以前没做过地图有关的项目，看到网上也没有完整有关地图的项目，就想起模仿一下摩拜单车app，我这个小项目包括附近车辆、规划路径、行驶距离、行驶轨迹记录、轨迹回放导航等（也挺全的哈）；
需要注意：
0、其中的附近车辆用的是假数据，实际项目中你上传自己的经纬度然后服务器端会返回给你附近车辆列表显示出来就行。行驶轨迹记录都是保存在本地数据库，实际项目中你可以隔几秒上传一次踩点列表到服务器，防止APP被杀死或其它异常导致以前踩点消失
1、距离是取两个位置点的直线距离，DistanceUtil.getDistance(lastLatLng, currentLatLng)。然后把所有这些距离相加就是总距离，这是通常算法 2、实际项目中可定时你上传当前位置，然后服务器返回给你附近自行车数据，你展示一下就行。
3、行驶轨迹就是开启后台Service每隔几秒收集一次经纬度，到最后必须把所有经纬度上传到服务器，这样就算app被卸载，重新安装你还可以获取到行驶轨迹。有两种思路，一是边收集变上传到服务器或数据库，这样可以防止手机重启或App被杀死导致以前的数据消失，二是等结束进程时上传到服务器。
4、百度内置导航语音播报的问题：能正常导航，但是无法语音播报？
除了地图显示、定位、导航需要的配置之外，tts播报需要添加白名单，点击进入配置地址。可参考：http://blog.csdn.net/chentravelling/article/details/51435976。
还有就是要分清提交时是debug版和release版的MD5，如果是测试版MD5那么发布版的语音还是没声音
发布版md5或sha获取方法：keytool -list -v -keystore /Users/gaolei/Work/CompanyProject/Bike/BiuBike/BiuBike/biubike.jks
测试版md5或sha获取方法：keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android
百度地图开放平台注册不需要公司营业执照什么的，个人就能注册，地址：http://lbsyun.baidu.com。
首先建议大家吧百度地图API的demo下载下来研究一下，它包含我们用到的所有知识点，你再把资源整合一下就行了。SDK的Demo下载地址：http://lbsyun.baidu.com/sdk/download?selected=mapsdk_basicmap,mapsdk_searchfunction,mapsdk_lbscloudsearch,mapsdk_calculationtool,mapsdk_radar
运行效果图
下面简单介绍一下有关内容，有需要的可以下载源码运行研究
1、初始化
SDKInitializer.initialize(getApplicationContext());//我测试在Application的onCreate()不行，必须在activity的onCreate()中
2、配置map参数
private void initMap() { // 地图初始化 mMapView = (MapView) findViewById(R.id.id_bmapView); mBaiduMap = mMapView.getMap(); // 开启定位图层 mBaiduMap.setMyLocationEnabled(true); // 定位初始化 mlocationClient = new LocationClient(this); mlocationClient.registerLocationListener(myListener); LocationClientOption option = new LocationClientOption(); option.setOpenGps(true); // 打开gps option.setCoorType("bd09ll"); // 设置坐标类型 option.setScanSpan(5000);//设置onReceiveLocation()获取位置的频率 option.setIsNeedAddress(true);//如想获得具体位置就需要设置为true mlocationClient.setLocOption(option); mlocationClient.start(); mCurrentMode = MyLocationConfiguration.LocationMode.FOLLOWING; mBaiduMap.setMyLocationConfigeration(new MyLocationConfiguration( mCurrentMode, true, null)); myOrientationListener = new MyOrientationListener(this); //通过接口回调来实现实时方向的改变 myOrientationListener.setOnOrientationListener(new MyOrientationListener.OnOrientationListener() { @Override public void onOrientationChanged(float x) { mCurrentX = x; } }); myOrientationListener.start(); mSearch = RoutePlanSearch.newInstance(); mSearch.setOnGetRoutePlanResultListener(this); initMarkerClickEvent(); }
3、获取当前地址
public class MyLocationListenner implements BDLocationListener { @Override public void onReceiveLocation(BDLocation bdLocation) { // map view 销毁后不在处理新接收的位置 if (bdLocation == null || mMapView == null) { return; } MyLocationData locData = new MyLocationData.Builder() .accuracy(bdLocation.getRadius()) .direction(mCurrentX)//设定图标方向 // 此处设置开发者获取到的方向信息，顺时针0-360 .latitude(bdLocation.getLatitude()) .longitude(bdLocation.getLongitude()).build(); mBaiduMap.setMyLocationData(locData); currentLatitude = bdLocation.getLatitude(); currentLongitude = bdLocation.getLongitude(); current_addr.setText(bdLocation.getAddrStr()); currentLL = new LatLng(bdLocation.getLatitude(), bdLocation.getLongitude()); startNodeStr = PlanNode.withLocation(currentLL); //option.setScanSpan(5000)，每隔5000ms这个方法就会调用一次，而有些我们只想调用一次，所以要判断一下isFirstLoc if (isFirstLoc) { isFirstLoc = false; LatLng ll = new LatLng(bdLocation.getLatitude(), bdLocation.getLongitude()); MapStatus.Builder builder = new MapStatus.Builder(); //地图缩放比设置为18 builder.target(ll).zoom(18.0f); mBaiduMap.animateMapStatus(MapStatusUpdateFactory.newMapStatus(builder.build())); changeLatitude = bdLocation.getLatitude(); changeLongitude = bdLocation.getLongitude(); if (!isServiceLive) { addOverLayout(currentLatitude, currentLongitude); } } } }
4、开启service来每隔几秒收集一次经纬度信息，保存到列表，然后通过broadcast把数据传到MainActivity来更新时间和距离UI信息
public class RouteService extends Service { private double currentLatitude, currentLongitude; private LocationClient mlocationClient = null; private MylocationListener mlistener; private BitmapDescriptor mIconLocation;

notification.contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); } private void initLocation() { mIconLocation = BitmapDescriptorFactory .fromResource(R.mipmap.location_marker); locationMode = MyLocationConfiguration.LocationMode.NORMAL; //定位服务的客户端。宿主程序在客户端声明此类，并调用，目前只支持在主线程中启动 mlocationClient = new LocationClient(this); mlistener = new MylocationListener(); // initMarkerClickEvent(); //注册监听器 mlocationClient.registerLocationListener(mlistener); //配置定位SDK各配置参数，比如定位模式、定位时间间隔、坐标系类型等 LocationClientOption mOption = new LocationClientOption(); //设置坐标类型 mOption.setCoorType("bd09ll"); //设置是否需要地址信息，默认为无地址 mOption.setIsNeedAddress(true); //设置是否打开gps进行定位 mOption.setOpenGps(true); //设置扫描间隔，单位是毫秒 当<1000(1s)时，定时定位无效 int span = 10000; mOption.setScanSpan(span); //设置 LocationClientOption mlocationClient.setLocOption(mOption); //初始化图标,BitmapDescriptorFactory是bitmap 描述信息工厂类. mIconLocation = BitmapDescriptorFactory .fromResource(R.mipmap.location_marker);

有关轨迹回放的原理是：截取所有记录point的一部分逐渐增加，然后显示，主要是通过handler，每隔1S增加截取一次，
Handler handler = new Handler() { public void handleMessage(Message msg) { currentIndex = currentIndex + spanIndex; Log.d("gaolei", "currentIndex------------" + currentIndex); routeBaiduMap.clear(); subList = points.subList(0, currentIndex); if (subList.size() >= 2) { OverlayOptions ooPolyline = new PolylineOptions().width(10) .color(0xFF36D19D).points(subList); routeBaiduMap.addOverlay(ooPolyline); } if (subList.size() >= 1) { LatLng latLng = points.get(subList.size() - 1); MarkerOptions options = new MarkerOptions().position(latLng) .icon(currentBmp); // 在地图上添加Marker，并显示 routeBaiduMap.addOverlay(options); MapStatusUpdate update = MapStatusUpdateFactory.newLatLng(latLng); // 移动到某经纬度 routeBaiduMap.animateMapStatus(update); } if (currentIndex < routePointsLength) { tv_current_time.setText(Utils.getDateFromMillisecond(routePoints.get(currentIndex).time)); tv_current_speed.setText(routePoints.get(currentIndex).speed + "km/h"); int progress = (int) currentIndex * 100 / routePointsLength; seekbar_progress.setProgress(progress); handler.sendEmptyMessageDelayed(1, 1000); } else { OverlayOptions ooPolyline = new PolylineOptions().width(10) .color(0xFF36D19D).points(points); routeBaiduMap.addOverlay(ooPolyline); seekbar_progress.setProgress(100); handler.removeCallbacksAndMessages(null); Toast.makeText(RouteDetailActivity.this, "轨迹回放结束", Toast.LENGTH_LONG).show(); } } };

遇到的大坑：
1、我的 百度 key肯定是没错，在魅族4.4系统上正常，而在三星C7 和coopad 106（都是6.0系统）不能正常显示，而是一片蓝，获取不到当前位置？如图
解决方法：原因是我设置targetVersion>=23，那么运行到6.0及以上设备时，默认所有权限都不开启，必须动态requestPermission，这里需要位置权限，默认没开启导致此结果，把targetVersion=22就行，当targetVersion<23时，默认开启全部权限。
1.2、地图只显示网格不显示建筑
解决方法：百度开放平台时 debug md5没配置正确，不同电脑或环境 debug md5 不一样，如果用我的项目直接运行可能就会出现这种情况，因为你的电脑环境debug md5和我的电脑环境debug md5不一样。你可以打一个release包 因为release md5如果用同一个签名是不会变的。你也可以在百度地图开放平台自己注册账号配置信息
2、仿DrawerLayout的覆盖型侧滑菜单，研究了好久，可参考：http://blog.csdn.net/gaolei1201/article/details/50404941，https://github.com/gaoleiandroid1201/DrawerLayout
3、位置图标不跟着自己运动，查看自己代码也没有问题啊，调试了好久，跑了不少冤枉路，莫名其妙
解决方法：把百度sdk中的初始化地图和配置参数等代码拷进来代替，果然奏效
4、进程保活，这个不能完全保活，只能尽量保活，除非是被加入白名单或自启应用像微信，但是有些 app像行者和咕咚就算app被杀死了也能活下来，有关进程保活可参考：https://mp.weixin.qq.com/s/d3scy-dC46NW9sz7wc3YLQ，https://segmentfault.com/a/1190000006251859
5、如果没有第三方导航APP，可以做百度地图内置导航，也耗费了不少时间。主要是官方Demo不能跑通，自带key验证不通过，还要自己研究
6、如果TTS语音导航SDK注册白名单注册不成功一直提示“registed Already”，可参考：http://bbs.lbsyun.baidu.com/forum.php?mod=viewthread&tid=90839
