Adding a Map with a Marker

By clustering your markers, you can put a large number of markers on a map without making the map hard to read. The marker clustering utility helps you manage multiple markers at different zoom levels. When a user views the map at a high zoom level, the individual markers show on the map. When the user zooms out, the markers gather together into clusters, to make viewing the map easier. The demo app provides a sample implementation of the marker clustering utility. Run the demo app shipped with the utility library by using one of these two methods:. Choose either Swift or Objective-C when prompted. CocoaPods updates your spec repositories, then opens the demo in a temporary Xcode project named SwiftDemoApp. If you haven't yet set up the library, follow the setup guide before reading the rest of this page. The following code defines a point of interestthe POIItem class, representing the markers to be managed in clusters on the map:. The library includes default implementations of the cluster algorithm and renderer. The following code randomly generates cluster items POIs within the scope of the map's camera, then feeds them to the cluster manager:. You can listen to map eventsbut you can't listen to the type-safe cluster manager events. When the user taps a marker, an individual cluster item, or a cluster, the API triggers mapView:didTapMarker: and attaches the extra cluster data to the marker. You can use conformsToProtocol to check what the user tapped. Typically, you implement both these protocols in the view controller that displays the map. Then call clusterManager. The cluster manager now intercepts any events that you've implemented on clusterManager. It forwards any remaining events to the map delegate, if provided. Note that events for standard markers that is, markers not generated by the cluster renderer are always forwarded to the map delegate. You can base your custom implementation on the sample implementation of these protocols included in the utility library, or you can code a fully custom implementation by fulfilling the protocols.

Animate marker position


Recently, someone asked me an interesting question about Google Maps. Is it possible to use Google Maps to track moving items? To download the sample app code, click here. My demo consists of two parts — the client and the server. Each truck has an ID, a name, and position value consisting of latitude and longitude. Here is an example of the dataset:. In my initial front end code, I simply built the code that would load the map, call the server, and display the markers as is. The only HTML-related aspect of this demo is the div used to store the map. Due to the simple nature of this demo, all of my JavaScript lives inside of there. I begin by laying out a map centered in Lafayette, LA. Assume we are a local shipping company and our server-side data represents our trucks. They have a simple little tool that lets you click on a map and retrieve latitude and longitude points. I used it both to center my map as well as create the initial points for my trucks. I basically clicked in a circle around the center of town. The important thing to remember is that it returns an array of data. I can take that array, iterate over it, and then simply create a marker for the truck. Note the use of setTimeout at the end. It can be. So — this by itself handles the basic operation — hit the server, render the markers. Whenever I build something I always start off simple and then iteratively update with new functionality. First, make note of the outside variable, markerStore. If you look back up to the data sample I provided above, you will note that each truck has an ID value. Otherwise I create a new marker and store a copy in the marker store. You could get a bit more fancy and modify the markers so they included an infowindow or perhaps their ID to help differentiate them. It is a simple Node application. I ended up using a random value between Unfortunately, if you run the demo long enough the trucks could easily move off the visible map. Real trucks would hopefully stick around town!

I included some dynamic variables pulled from the Application file into the scripting. I added a marker, and a popup bubble to it. Have no reason at this point to track anything such as vehicles, but was nice upgrade for me and some of my clients.

Instead I would like to show it this way:. Active Oldest Votes. Didn't really change anything. It always shows the marker at the top left corner. I think it's the way Google Map processes the LatLng. If I give it a markers position it takes it as an anchor point and than show the rest of the map based on zoom from that point. It doesn't understand it as a center. But I'm not sure, it's just my understanding. I found a workaround. Will keep digging for a better solution. Sign up or log in Sign up using Google. Sign up using Facebook.

I have googleMap v2 with polyline that presents a route between the user current location and the destination point. Now, I want to update the polyline according to the user moving. I tried to redrawing the whole polyline when location is changed but the polyline is flickering. I didn't find any appropriate function in the PolylineOptions class the function add is only to add a vertex but not to update or remove do you have any idea how to update the polyline??? We can do this by changing the points of that polyline. Check below code. How are we doing? Please help us improve Stack Overflow. Take our short survey. Learn more. Asked 6 years, 10 months ago. Active 1 year, 7 months ago. Viewed 12k times. Active Oldest Votes. The only way as of version 3. Thanks for the Awesome answer. Can you help me? Very good. But I wouldn't create a new List for polyline. I think it is a good practice to have a List that stores all the pointsupdate the List when needed and use that in polyline. This is because when you have a huge list, Garbage Collector has to clean the new instance of that List as the app won't use it. But i need polyline update route wise.

Markers indicate single locations on the map. You can customize your markers by changing the default color, or replacing the marker icon with a custom image. Info windows can provide additional context to a marker. The ApiDemos repository on GitHub includes a sample that demonstrates various marker features:. Markers identify locations on the map. The default marker uses a standard icon, common to the Google Maps look and feel. It's possible to change the icon's color, image or anchor point via the API. Markers are objects of type Markerand are added to the map with the GoogleMap. Markers are designed to be interactive. They receive click events by default, and are often used with event listeners to bring up info windows. Setting a marker's draggable property to true allows the user to change the position of the marker. Use a long press to activate the ability to move the marker. By default, when a user taps a marker, the map toolbar appears at the bottom right of the map, giving the user quick access to the Google Maps mobile app. You can disable the toolbar. For more information, see the guide to controls. The following example demonstrates how to add a marker to a map. The marker is created at coordinates 10,10and displays the string 'Hello world' in an info window when clicked. A common requirement is to show additional information about a place or location when the user taps a marker on the map. See the guide to info windows. You can store an arbitrary data object with a marker using Marker. Here are some examples of scenarios when it's useful to store and retrieve data with markers:. You can reposition a marker once its been added to the map so long as its draggable property is set to true. Long press the marker to enable dragging. When you take your finger off the screen, the marker will remain in that position. Markers are not draggable by default. You must explicitly set the marker to be draggable either with MarkerOptions.
