 1、GPSData中可添加车辆数据并标注于MainMap中，ListView同步显示该车辆信息；

 

            double vehilceID = double.Parse(txtID.Text, CultureInfo.InvariantCulture);
            double lat = double.Parse(txtLat.Text, CultureInfo.InvariantCulture);
            double lng = double.Parse(txtLng.Text, CultureInfo.InvariantCulture);

            GMapMarkerRect car = new GMapMarkerRect(new PointLatLng(lat, lng));
            MainMap.Position = car.Position;
            
            GMapMarkerGoogleGreen carMarker = new GMapMarkerGoogleGreen(car.Position);
            {
                carMarker.Tag = -1;
                carMarker.VehicleID = vehilceID;
                carMarker.ToolTipMode = MarkerTooltipMode.OnMouseOver;
            }

            Placemark p = null;
            if (checkBoxPlacemarkInfo.Checked)
            {
                p = GMaps.Instance.GetPlacemarkFromGeocoder(car.Position);
            }

            if (p != null)
            {
                carMarker.ToolTipText = p.Address;
            }
            else
            {
                carMarker.ToolTipText = car.Position.ToString();
            }

            objects.Markers.Add(carMarker);
            ListViewItem lstview = new ListViewItem(carMarker.VehicleID.ToString());
            listView1.Items.Add(lstview);
            lstview.SubItems.Add(carMarker.Position.Lat.ToString());
            lstview.SubItems.Add(carMarker.Position.Lng.ToString());

 

 

 2、点击地图中车辆图标：车辆图标居中并显示该点位置信息、ListView选中相应项；

 

                    if (item.Tag != null)
                    {
                        if (currentTransport != null)
                        {
                            currentTransport.ToolTipMode = MarkerTooltipMode.OnMouseOver;
                            currentTransport = null;
                        }

                        if (item.Tag.Equals(-1))
                        {
                            //车辆图标点击事件
                            MainMap.Position = item.Position;
                            foreach (ListViewItem i in this.listView1.Items)
                            {
                                if(double.Parse(i.Text).Equals(item.VehicleID))
                                {
                                    i.Selected = true;
                                    listView1.Focus();
                                }
                            }

                            //MessageBox.Show(string.Format("ID:{0}, 纬度: {1}, 经度: {2}", item.VehicleID, item.Position.Lat.ToString(), item.Position.Lng.ToString()));
                        }

                        currentTransport = item;
                        currentTransport.ToolTipMode = MarkerTooltipMode.Always;
                    }

 

 

 3、ListView选择车辆信息：地图中相应车辆图标居中并显示该点位置信息；

 

            foreach(GMapMarker gmarker in objects.Markers)
            {
                if (gmarker.VehicleID.Equals(double.Parse(listView1.SelectedItems[0].Text)))
                {
                    MainMap_OnMarkerClick(gmarker, e);
                    //MainMap.Position=gmarker.Position;
                    //gmarker.ToolTipMode = MarkerTooltipMode.Always;
                }
            }
            if (e.Button == MouseButtons.Right && this.listView1.SelectedItems.Count > 0)
            {
                this.contextMenuStrip1.Show(this.listView1, e.Location);
            }
