1.基本地图显示
MapView:定义地图容器
AMap:地图控制 包括显示交通 定位层显示配置
>初始化容器MapView
>配置信息
private void init() { if (aMap == null) { aMap = mapView.getMap(); } }2.通过AMap显示交通
aMap.setTrafficEnabled(true);
3.Location定位功能
>设置当前位置的配置
private void setUpMap() { MyLocationStyle locationStyle=new MyLocationStyle(); locationStyle.strokeColor(Color.BLACK); locationStyle.strokeWidth(1.0f); locationStyle.radiusFillColor(0x8333); locationStyle.myLocationIcon(BitmapDescriptorFactory.fromResource(R.drawable.location_marker)); aMap.setMyLocationStyle(locationStyle);//设置定位点样式 aMap.setLocationSource(this);//设置监听 aMap.setMyLocationEnabled(true);//启动定位图层}>继承LocationSource,定位监听开始和结束
@Overridepublic void activate(OnLocationChangedListener arg0) { mLocationChangedListener=arg0; if (mLocationManager==null) { mLocationManager=LocationManagerProxy.getInstance(this); //调用控制 每2秒更新1次，其主要的实时更改在最后一个参数AMapLocationListener mLocationManager.requestLocationUpdates(LocationProviderProxy.AMapNetwork, 2000, 10, this); }}@Overridepublic void deactivate() { mLocationChangedListener=null; if (mLocationManager!=null) { mLocationManager.removeUpdates(this); mLocationManager.destroy(); mLocationManager=null; }}>继承AMapLocationListener,主要实现onLocationChanged修改位置
@Overridepublic void onLocationChanged(AMapLocation arg0) { if (mLocationChangedListener!=null && arg0!=null) { mLocationChangedListener.onLocationChanged(arg0); }}4.定位中 实时更改方向和位置，默认的定位只是简单的图片 没有涉及方向等(思路：添加标记并用传感器修改指示方向)
>初始化传感器
mSensorManager=(SensorManager)getSystemService(Context.SENSOR_SERVICE);mSensor=mSensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION);
>初始化Marker，
private void setUpMap() { mGPSMarker=aMap.addMarker(new MarkerOptions() .icon(BitmapDescriptorFactory.fromResource(R.drawable.location_marker)) .anchor(0.5f, 0.5f)); aMap.setLocationSource(this); aMap.setMyLocationEnabled(true);}>启动位置监听器时注册传感器 关闭时注销
@Overridepublic void activate(OnLocationChangedListener arg0) { //.... mSensorManager.registerListener(this, mSensor, SensorManager.SENSOR_DELAY_NORMAL);}@Overridepublic void deactivate() { //..... mSensorManager.unregisterListener(this, mSensor);}>位置移动时修改Marker
@Overridepublic void onLocationChanged(AMapLocation arg0) { if (mLocationChangedListener!=null && arg0!=null) { mLocationChangedListener.onLocationChanged(arg0); mGPSMarker.setPosition(new LatLng(arg0.getLatitude(),arg0.getLongitude())); }}>位置角度转换时修改Marker
@Overridepublic void onSensorChanged(SensorEvent event) { if (System.currentTimeMillis() - lastTime < TIME_SENSOR) { return; } switch (event.sensor.getType()) { case Sensor.TYPE_ORIENTATION: { float x = event.values[0]; x += getScreenRotationOnPhone(this); x %= 360.0F; if (x > 180.0F) x -= 360.0F; else if (x < -180.0F) x += 360.0F; if (Math.abs(mAngle -90+ x) < 3.0f) { break; } mAngle = x; if (mGPSMarker != null) { mGPSMarker.setRotateAngle(-mAngle); aMap.invalidate(); } lastTime = System.currentTimeMillis(); } }}/** * 获取当前屏幕旋转角度 * * @param activity * @return 0表示是竖屏; 90表示是左横屏; 180表示是反向竖屏; 270表示是右横屏 */public static int getScreenRotationOnPhone(Context context) { final Display display = ((WindowManager) context .getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay(); switch (display.getRotation()) { case Surface.ROTATION_0: return 0; case Surface.ROTATION_90: return 90; case Surface.ROTATION_180: return 180; case Surface.ROTATION_270: return -90; } return 0;}5.设置缩放和显示位置
LatLngBounds bounds=new LatLngBounds.Builder() .include(new LatLng(22.117719,112.323274)) .include(new LatLng(22.117719,114.323274)) .include(new LatLng(24.117719,112.323274)) .include(new LatLng(24.117719,114.323274)) .build();aMap.moveCamera(CameraUpdateFactory.newLatLngBounds(bounds, 10));aMap.moveCamera(CameraUpdateFactory.zoomBy(8));aMap.setOnMapLoadedListener(this);//设置地图显示监听器
6.设置标记
ArrayList<BitmapDescriptor> icons=new ArrayList<BitmapDescriptor>();icons.add(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_BLUE));//... aMap.addMarker(new MarkerOptions().icons(icons)//显示多图片 .period(2)//变化周期 .position(new LatLng(23.118674,113.321614)) .anchor(0.5f, 0.5f)//锚点位置 .title("fuliyinkai")//点击显示文字 ).showInfoWindow();//默认显示aMap.setInfoWindowAdapter(this);//点击标记 显示自定义浮动View7.设置圆形
aMap.addCircle( new CircleOptions().center(new LatLng(23.118674,113.321614)) .fillColor(0x88888888).strokeColor(Color.BLACK) .strokeWidth(5).radius(400));
8.获取周围关键字查询
>文字查找
Inputtips inputtips=new Inputtips(this,new InputtipsListener() { @Override public void onGetInputtips(List<Tip> tips, int arg1) { tip.getName()//获取匹配的单个数据名字 } });try { inputtips.requestInputtips(content,"");} catch (AMapException e) { e.printStackTrace();}>地图获取相关位置
// 第一个参数表示搜索字符串，第二个参数表示poi搜索类型，第三个参数表示poi搜索区域（空字符串代表全国）query = new PoiSearch.Query(keyWord, "", editCity.getText().toString());query.setPageSize(10);// 设置每页最多返回多少条poiitemquery.setPageNum(currentPage);// 设置查第一页poiSearch = new PoiSearch(this, query);poiSearch.setOnPoiSearchListener(this);//主要执行onPoiSearched()poiSearch.searchPOIAsyn();@Overridepublic void onPoiSearched(PoiResult result, int rCode) { dissmissProgressDialog();// 隐藏对话框 if (rCode == 0) { if (result != null && result.getQuery() != null) {// 搜索poi的结果 if (result.getQuery().equals(query)) {// 是否是同一条 poiResult = result; // 取得搜索到的poiitems有多少页 List<PoiItem> poiItems = poiResult.getPois();// 取得第一页的poiitem数据，页数从数字0开始 List<SuggestionCity> suggestionCities = poiResult .getSearchSuggestionCitys();// 当搜索不到poiitem数据时，会返回含有搜索关键字的城市信息 if (poiItems != null && poiItems.size() > 0) { aMap.clear();// 清理之前的图标 PoiOverlay poiOverlay = new PoiOverlay(aMap, poiItems); poiOverlay.removeFromMap(); poiOverlay.addToMap(); poiOverlay.zoomToSpan(); } else if (suggestionCities != null && suggestionCities.size() > 0) { showSuggestCity(suggestionCities); } else { ToastUtil.show(PoiKeywordSearchActivity.this, R.string.no_result); } } } else { ToastUtil.show(PoiKeywordSearchActivity.this, R.string.no_result); } } else if (rCode == 27) { ToastUtil.show(PoiKeywordSearchActivity.this, R.string.error_network); } else if (rCode == 32) { ToastUtil.show(PoiKeywordSearchActivity.this, R.string.error_key); } else { ToastUtil.show(PoiKeywordSearchActivity.this, getString(R.string.error_other) + rCode); }}9.查询route
FromAndTo fromAndTo=new FromAndTo(mCurrenLocationPoint, latLonPoint); // 第一个参数表示路径规划的起点和终点，第二个参数表示驾车模式，第三个参数表示途经点，第四个参数表示避让区域，第五个参数表示避让道路 DriveRouteQuery query = new DriveRouteQuery(fromAndTo, RouteSearch.DrivingDefault, null, null, ""); routeSearch=new RouteSearch(this); routeSearch.setRouteSearchListener(this); routeSearch.calculateDriveRouteAsyn(query);// 异步路径规划驾车模式查询>route监听器
@Override public void onBusRouteSearched(BusRouteResult arg0, int arg1) { } @Override public void onDriveRouteSearched(DriveRouteResult result, int rCode) { if (rCode != 0) { return; } if (result != null && result.getPaths() != null && result.getPaths().size() > 0) { driveRouteResult = result; DrivePath drivePath = driveRouteResult.getPaths().get(0); aMap.clear();// 清理地图上的所有覆盖物 DrivingRouteOverlay drivingRouteOverlay = new DrivingRouteOverlay( this, aMap, drivePath, driveRouteResult.getStartPos(), driveRouteResult.getTargetPos()); drivingRouteOverlay.removeFromMap(); drivingRouteOverlay.addToMap(); drivingRouteOverlay.zoomToSpan(); } } @Override public void onWalkRouteSearched(WalkRouteResult arg0, int arg1) { }
