Google maps polyline with markers android
A polyline is a list of points, where line segments are drawn between consecutive points. A polyline has the following properties:. Methods in this class must be called on the Android UI thread. If not, an IllegalStateException will be thrown at runtime. For more information, read the Shapes developer guide. Tests if this Polyline is equal to another. Gets the joint type used at all vertices of the polyline except the start and end vertices.
See JointType for possible values. Returns a snapshot of the vertices of this polyline at this time. The list returned is a copy of the list of vertices and so changes to the polyline's vertices will not be reflected by this list, nor will changes to this list be reflected by the polyline. To change the vertices of the polyline, call setPoints List. Gets the clickability of the polyline. If the polyline is clickable, your app will receive notifications to the GoogleMap.How to draw polyline between two points on google maps in android -- Draw route between two points
OnPolylineClickListener when the user clicks the polyline. Removes this polyline from the map. After a polyline has been removed, the behavior of all its methods is undefined.
Sets the clickability of the polyline. Sets the cap at the end vertex of this polyline. The default end cap is ButtCap. Sets the joint type for all vertices of the polyline except the start and end vertices. See JointType for allowed values. Sets the stroke pattern of the polyline. The default stroke pattern is solid, represented by null.
Sets the points of this polyline. This method will take a copy of the points, so further mutations to points will have no effect on this polyline. Sets the cap at the start vertex of this polyline. The default start cap is ButtCap. You can use this property to associate an arbitrary Object with this polyline. For example, the Object can contain data about what the polyline represents. It is your responsibility to call setTag null to clear the tag when you no longer need it, to prevent memory leaks in your app.

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.This Android tutorial is to demonstrate a sample application which will draw path for a route in Google map using Android API v2.
This tutorial is a part of Google maps series. This earlier tutorial is to draw straight lines polyline between given latitude and longitude. Pre-requisite is same for all Google maps tutorial and so I am not going to repeat it again, so to setup the development environment, to get the Android API key and related preparations please go through the previous tutorial link given above.
Above shown image is the output of the example Android app. I have chose three locations and drawn path between them. Those three locations are shown by Android markers. This Google service calculates direction between given locations. BufferedReader; import java. IOException; import java. InputStream; import java.
InputStreamReader; import java. HttpURLConnection; import java. URL; import android. Can you please explain why? The code highlighter has swallowed some part and showing the remaining.
I will fix them now. Very easy working implementation. Frankly did not understand anything of the code. Possibly you could give an explanation for how the code works! What if i want to add marker dynamically based on latitude and longitude? How do i draw path between two city which is enter by user in two edittext and distance between them? In my eclipse. Can you help me with that?
Any suggestions? For the sake of this example, let's use a simple 4-point polyline, with a total length of circa 8, meters. The snippet below will define this polyline and will render it on the map:. In particular I have adapted the following two methods from the above source to work with Google's GLatLng class:. These were used to extend Google's GLatLng class with a method moveTowardswhich when given another point and a distance in meters, it will return another GLatLng along that line when the distance is travelled from the original point towards the point passed as a parameter.
Simply apply the moveTowards method to the current point, passing the next point and the distance to travel. Return the result and break the iteration. We need to subtract the distance between this point and the next point from the total distance to travel along the path. Continue through the iteration with the modified distance. You may have noticed that we can easily implement the above recursively, instead of iteratively. So let's do it:. With the above method, if we define an array of GLatLng points, and we invoke our moveAlongPath function with this array of points and with a distance of 2, meters, it will return a GLatLng on that path at 2.
Therefore all we need to do is to call moveAlongPath for each check point we need on the path. If you need three markers at 1km, 5km and 10km, you can simply do:.
Note however that moveAlongPath may return null if we request a check point further from the total length of the path, so it will be wiser to check for the return value before passing it to new GMarker. We can put this together for the full implementation. In this example we are dropping a marker every 1, meters along the 8. I found out why I had the inexactitude. As a basic algorithm you could iterate over all the points in the Polyline, and calculate the cumulative distance - if the next segment puts you over your distance, you can interpolate the point where the distance has been reached - then simply add a point of interest to your map for that.
I wanted to port Daniel Vassalo's answer to iOS, but it wasn't worked properly and some markers were misplaced until I changed. So if anyone having a trouble to figure out why are the markers are misplaced, try this and maybe it will help.We all know how important maps have been to Android Apps.
Maps in mobile applications have taken user expereince to a whole new level. In this example we will look into how to add a Google map into your application. After adding we will explore different ways with which it can be customized. Steps on how to register your app are mentioned here. Add the following fragment to the layout file for your MapsActivity. Placing the SupportMapFragment is the simplest way of displaying a map in your app.
SupportMapFragment is basically a wrapper around a MapView to automatically handle the necessary life cycle needs. If you are using Android Studio and want to show your map inside an activity integrating Google map is very simple.
You will just have to follow the following steps. You just need to call the following method on the map object as shown below.
Besides this changing a map type would change the look and feel of your application. Google APIs come with four different types of maps. You can change the map type by just calling a single method on the map object. Markers are used to indicate any specific location on the map. A marker can be added on any location on the map. In the above example we add a marker on the city of sydney by passing its co ordinates and have also set the title and snippet for it.
One of the most useful feature of a marker is that we can change the icon of the marker to anything we like. Our new custom marker icon can be taken from the device storeage, app resources or even can be retreived from web.
Icon for marker should be a BitmapDescriptor. You can have any image from your app resources as the marker icon. Just add the following code as shown below. A polyline is basically a list of points, where line segments are drawn between consecutive points.
Polylines are used to denote paths on the map. All the points are basically LatLng location with each of them having latitude and longitude co ordinates. Polylines are drawn with the help of PolylineOptions.This tutorial shows you how to add a Google map to your Android app, and use polylines and polygons to represent routes and areas on a map.
The recommended development environment is Android Studio. Get Started. For more details, see the full guide to getting an API key. When you build your app, Gradle copies the API key into the app's Android manifest, as explained below.
Android Studio invokes Gradle to build the app, and then runs the app on the device or on the emulator. You should see a map with two polygons overlaid on top of Australia, similar to the image on this page. This part of the tutorial explains the most significant parts of the Polygons app, to help you understand how to build a similar app. Note the following elements in your app's AndroidManifest. Add a meta-data element to embed the version of Google Play services that the app was compiled with.
Add a meta-data element specifying your API key. When you build your app, Gradle copies the API key from your project's gradle. To see how the API key maps to the string value, take a look at your app's build.
This element defines a SupportMapFragment to act as a container for the map and to provide access to the GoogleMap object. The tutorial uses the Android support library version of the map fragment, to ensure backward compatibility with earlier versions of the Android framework. In your activity's onCreate method, set the layout file as the content view.
Get a handle to the map fragment by calling FragmentManager. Then use getMapAsync to register for the map callback:. The API invokes this callback when the GoogleMap object is available, so you can add objects to the map and further customize it for your app:. A Polyline is a series of connected line segments. Polylines are useful to represent routes, paths, or other connections between locations on the map. Create a PolylineOptions object and add points to it.
Each point represents a location on the map, which you define with a LatLng object containing latitude and longitude values. The code sample below creates a polyline with 6 points.
