百度地图自定义多点规划路线

快来打我* 2022-08-04 10:43 655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
    	}

在最后重申我的这几个小问题

1.当调用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

2.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（list里有这些信息）

3.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

的primary key

希望能得到帮助，感谢。
