百度地图自定义多点规划路线 快来打我* 2022-08-04 10:43 451阅读 0赞 所谓自定义多点规划路线，就是从服务器下载多点的坐标，标注在百度地图上，在按照一定顺序连接规划路线。 （由于本人也是实习小白，所以有做错的，费事麻烦的欢迎大神指出，让我少走点弯路^^） 好戏开始~~（先局部，再整体） 首先数据库文件就省略了，第一是我还没研究明白，第二太多（如果有需要可以找我） 1.这个是spinner，用来选择URL，然后返回到数据库，数据库下载该URL的站点信息。（获取lineName，switch相应的“部分url”，用静态方法返回拼接数据库中URL） <span style="white-space:pre"> </span>zdlist.add("浦电线"); zdlist.add("华苑线"); zdlist.add("海泰线"); // zdlist.add("福州"); // zdlist.add("厦门"); lineAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, zdlist); lineAdapter .setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); lineSpinner = (Spinner) findViewById(R.id.spinner1); lineSpinner.setAdapter(lineAdapter); lineSpinner .setOnItemSelectedListener(new Spinner.OnItemSelectedListener() { public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) { String lineName = lineSpinner.getSelectedItem() .toString(); SelectURL.SURL(lineName); System.out.println("您选择的是：" + lineAdapter.getItem(arg2)); arg0.setVisibility(View.VISIBLE); } public void onNothingSelected(AdapterView<?> arg0) { System.out.println("NONE"); arg0.setVisibility(View.VISIBLE); } }); /* 下拉菜单弹出的内容选项触屏事件处理 */ lineSpinner.setOnTouchListener(new Spinner.OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { // TODO Auto-generated method stub return false; } }); /* 下拉菜单弹出的内容选项焦点改变事件处理 */ lineSpinner .setOnFocusChangeListener(new Spinner.OnFocusChangeListener() { public void onFocusChange(View v, boolean hasFocus) { // TODO Auto-generated method stub } }); 2.这个是标注点点击事件跟地图点击事件。这个泡泡就是这样显示，点击地图消失。（注意：当你调用BaiduMap.OnMapClickListener这个接口时，点击地图时hideInfoWindow出于某种原因可能不起作用，这也是我想向各位大神请教的。我的方法用bdMap重写这个方法，是可以的。）我做安卓没多长时间，对泛型接触的不是很多，在我的List<ZhanDianUtil>里有站点名称站点经度纬度等等，请问各位大神，我用点击Marker返回的经纬度可不可以匹配到list里相应的站点，从而获取其站点名称？ // 地图标注点击处理 bdMap.setOnMarkerClickListener(new OnMarkerClickListener() { @Override public boolean onMarkerClick(Marker mMaker) { // TODO Auto-generated method stub // 泡泡 List<ZhanDianUtil> zdu = new ArrayList(); LatLng a = mMaker.getPosition(); String b = "车站"; popupText = new TextView(BusLineSelectActivity.this); popupText.setBackgroundResource(R.drawable.popup); popupText.setTextColor(0xFF000000); popupText.setText(b); popupText.setGravity(Gravity.CENTER); bdMap.showInfoWindow(new InfoWindow(popupText, a, 0)); return false; } }); bdMap.setOnMapClickListener(new OnMapClickListener() { @Override public boolean onMapPoiClick(MapPoi arg0) { // TODO Auto-generated method stub return false; } @Override public void onMapClick(LatLng arg0) { // TODO Auto-generated method stub bdMap.hideInfoWindow(); } }); } 3.这个是获取数据库中点的坐标画在地图上，站点嘛， 问题：如果不删除数据库文件，情况1在更换路线时还保留之前的站点，clear地图时还会在画出来，情况2显示不是唯一primary key，求解！！ @SuppressLint("HandlerLeak") private void zhanDianXianShi() { // TODO Auto-generated method stub new Thread(new Runnable() { @Override public void run() { // 删除本地数据库信息 bmydb.deleteZhanDianUtil(); bmydb.deleteZhanDianLocalUtil(); bmydb.downloadZhanDian(); drivingSearch(drivintResultIndex); Message msgDown = new Message(); Bundle b = new Bundle();// 存放数据 b.putInt("result", 2); msgDown.setData(b); handler.sendMessage(msgDown); // 发送消息 Log.i("更新车辆数据：", "ok"); } }).start(); // 开启线程 handler = new Handler() { @Override public void handleMessage(Message msg) { super.handleMessage(msg); Bundle data = msg.getData(); int iReturnVal = data.getInt("result"); Log.i("bus update", "车辆同步结果为-->" + String.valueOf(iReturnVal)); // UI界面的更新等相关操作 if (2 == iReturnVal) { String msgFinish = "站点查询完成"; Toast.makeText(getApplicationContext(), msgFinish, Toast.LENGTH_SHORT).show(); List<ZhanDianUtil> listBuss = null; listBuss = bmydb.searchBusList(); for (int i = 0; i < listBuss.size() / 2; i++) { double Latitude = listBuss.get(i).getLat(); double Longitude = listBuss.get(i).getLng(); int busid = listBuss.get(i).getZhanDianid(); BitmapDescriptor bitmap; // 构建图标 bitmap = BitmapDescriptorFactory .fromResource(R.drawable.icon_gcoding); if (busid == 0) { // 构建Marker bitmap = BitmapDescriptorFactory .fromResource(R.drawable.icon_gcoding); } LatLng ll = new LatLng(Latitude, Longitude); // 构建MarkerOption，用于在地图上添加Marker OverlayOptions option = new MarkerOptions() .position(ll).icon(bitmap).zIndex(9) // 设置marker所在层级 .draggable(true); // 设置手势拖拽; // 在地图上添加Marker，并显示 mMakerBus = (Marker) (bdMap.addOverlay(option)); String strMaker = "maker-zhandian" + String.valueOf(i); Bundle bundle = new Bundle(); bundle.putSerializable("ZhandianUtil", listBuss.get(i)); mMakerBus.setExtraInfo(bundle); Log.d(strMaker, ll.toString()); makerBus.add(mMakerBus); System.out.println("画站点啊啊啊啊啊啊"); MapStatusUpdate u = MapStatusUpdateFactory .newLatLng(ll); bdMap.animateMapStatus(u); // ll = null; } isMark = true; } else { String msgFinish = "站点查询失败"; Toast.makeText(getApplicationContext(), msgFinish, Toast.LENGTH_SHORT).show(); } } }; } 4.重点来了，这个就是连点成线的关键代码，其实就一句话 drivingOption.passBy(lu); 但是我要提几个我认为我代码里的重点。 1)泛型，当你需要将一个泛型中的某一个值，比如说是经度，这时候用到的get和set点对点的赋值。例d1.setLng(d2.getLng)。当你需要像代码中一样，不是点对点，要将精度跟纬度合成这个LatLng ll，这时候应用add这个方法。 2）drivingOption.passBy(lu);lu是List<PlanNode>的对象而且必须是List对象，list里就是经过的点。除此之外，必须要起点和终点。OK /** * 驾车线路查询 */ private void drivingSearch(int index) { List<ZhanDianUtil> zdu = new ArrayList(); List<PlanNode> lu = new ArrayList(); zdu = bmydb.searchBusList(); int endn = zdu.size() / 2 - 1; System.out.println(endn); double lat = zdu.get(0).getLat(); double lng = zdu.get(0).getLng(); LatLng stall = new LatLng(lat, lng); LatLng endll = new LatLng(zdu.get(endn).getLat(), zdu.get(endn) .getLng()); for (int i = 0; i < zdu.size() / 2; i++) { double Latitude = zdu.get(i).getLat(); double Longitude = zdu.get(i).getLng(); LatLng ll = new LatLng(Latitude, Longitude); PlanNode node = PlanNode.withLocation(ll); lu.add(node); } DrivingRoutePlanOption drivingOption = new DrivingRoutePlanOption(); drivingOption.from(PlanNode.withLocation(stall)); drivingOption.to(PlanNode.withLocation(endll)); drivingOption.passBy(lu); routePlanSearch.drivingSearch(drivingOption);// 发起驾车路线规划 } 下面就贴上这个activity的源码，如还有不懂的可以和我交流 package com.zwin.activity; import java.io.IOException; import java.io.UnsupportedEncodingException;
