Since the last two weeks i am developing a Navigation App.
I want to set an Pointer that is showing me the current Location.
How I can make this without using the Marker ? Or did I have to use the Marker ?
If you want to display the current location, you can use one of the following osmdroid Overlays:
MyLocationOverlay or MyLocationNewOverlay: handling GPS positionning
Or DirectedLocationOverlay: GPS position/direction/precision to handle yourself.
By the way, Marker(MapView) should be defined... Your OSMBonusPack lib is probably not installed properly.
Marker startMarker = new Marker(mapView);
startMarker.setPosition(gp);
startMarker.setAnchor(Marker.ANCHOR_CENTER, Marker.ANCHOR_BOTTOM);
mapView.getOverlays().add(startMarker);
mapView.invalidate();
startMarker.setIcon(getResources().getDrawable(R.drawable.iconcurrentlocation));
startMarker.setTitle("Start point");
with this one u can set immag on yout cuurentLocation and the Important thing is that you have to import this
import org.osmdroid.bonuspack.overlays.Marker;
I hope this helps somebody

I'm trying to develop an offline navigation app for Trekking.
The app shows to the user a list of nearby track/routes where he can go.
Examples:
-Walking to Etna Vulcan
-Walking in the wood.
I've several KML files provided to me by local guides, each one for a different track.
So, if i choose "Walking to Etna Vulcan", I will have a Map with the track that I've to follow to go the Etna Vulcan, with some markers of interesting point (Examples: Refuges, Monuments). This data is actually ready, in KML format.
So:
The user chooses the track from the list that I provide, then the phone shows the track on the map(from kml or equivalent) with the current user position.
I'm doing it with MapBox sdk (but i'm open to alternatives).
Actually, I've successfully downloaded an offline map of the zone (Sicily), but i'm note sure how to write my kml on the map.
I also imported a kml in Mapbox Studio, but i don't know how to download a MapBox Studio Map into my application.
Thank you for your time!
If Mapbox seems like a good alternative then you just need to study their Android SDK to see if and how drawing markers and coordinate tracks are supported.
For the tracks see https://www.mapbox.com/android-sdk/geojson/
The relevant (to you) part is right at the end of their example code:
LatLng[] pointsArray = points.toArray(new LatLng[points.size()]);
// Draw Points on MapView
mapboxMap.addPolyline(new PolylineOptions()
.add(pointsArray)
.color(Color.parseColor("#3bb2d0"))
.width(2));
Here they have the coordinate points in the points ArrayList. They have been extracted from GeoJSON data, but you would just need to extract the coordinate points from the KML data and then draw the track based on that example.
For markers see https://www.mapbox.com/android-sdk/marker/
They have this example code:
mapboxMap.addMarker(new MarkerOptions()
.position(new LatLng(48.13863, 11.57603))
.title("Hello World!")
.snippet("Welcome to my marker."));
For a marker with a custom icon see https://www.mapbox.com/android-sdk/custom-marker-icon/
They have this example code:
// Create an Icon object for the marker to use
IconFactory iconFactory = IconFactory.getInstance(MainActivity.this);
Drawable iconDrawable = ContextCompat.getDrawable(MainActivity.this, drawable.ic_directions_boat_black_18dp);
Icon icon = iconFactory.fromDrawable(iconDrawable);
// Add the custom icon marker to the map
mapboxMap.addMarker(new MarkerOptions()
.position(new LatLng(-33.8500000, 18.4158234))
.title("Cape Town Harbour")
.icon(icon));
So you would just use a regular Android Drawable for the custom icon.
Looks quite convenient. I haven't used the Mapbox SDK myself.
I have created an application in which I am trying to show user's movement by animating marker position.
Using Google map V2.
Location updates using location client.
Animating marker using new location.
But comparing with Google map navigation, there is no continuity in rendering navigation.
Can anyone suggest a better approach? Thanks!
For continuity, I think you need to fetch regular location updates from location client by giving location request like this.
LocationRequest request = LocationRequest.create()
.setInterval(0).setFastestInterval(0)
.setSmallestDisplacement(0)
.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
Then for smooth animation you can follow the approach Steve Benett mentioned. here
The last case you mentioned in the comment about the path. I also had the same issue in one of my app. I tried with gps route simulator app to mock a route. then comparing my app and google map, googlemap followed the correct road path while my app's marker was moving slightly shifted from road. Then I tried some tweaks with marker. Like this
mPositionMarker = mMap.addMarker(new MarkerOptions()
.flat(true)
.icon(BitmapDescriptorFactory
.fromResource(R.drawable.positionIndicator))
.anchor(0.5f, 0.5f)
.position(
new LatLng(location.getLatitude(), location
.getLongitude())));
This worked for me. This positioned my marker on same location as of google map. (Depends on the accuracy of location though).
Thanks for the answer here
I have a specific problem with Google Maps for Android. I should be able to make Google Maps look like the map on this page www.bam.brno.cz, but I'm new to Goole Maps for Android so I don't know if there's a way to do it.
I don't have any of those map images, but i guess there should be a way to get it from the internet (like WMS or something). If I was eventually able to save them and use them offline that would be great, but if not and the app would have to use data connection, it's also ok.
I already got app with google maps, so the question is just about how to get the map images and replace default google maps images.
Also if that wouldn't be posible, I would like to know what other options I have(like if theres some other map images I can use and how)
PS: not sure how it's called correctly: map images/map tiles
EDIT: I don't care about the objects, I know how to do them. I don't know how to get the whole map, the tiles it's made from. I'm already familiar with markers and camera moving etc.
Yes you can use marker for same.
You can try some thing like ..
m = myMap.addMarker(new MarkerOptions()
.position(new LatLng(startLatLng.latitude, startLatLng.longitude))
.title("Vivek Test"));
Here m is Marker;
and myMap is GoogleMap
Complete structure like this ..
myMap = ((SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map)).getMap();
//myMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
myMap.setMyLocationEnabled(true);
myMap.moveCamera(CameraUpdateFactory.newLatLng(startLatLng));
myMap.animateCamera(CameraUpdateFactory.zoomTo(20), 2000, null);
m = myMap.addMarker(new MarkerOptions()
.position(new LatLng(startLatLng.latitude, startLatLng.longitude))
.title("Vivek Test"));
Hope it helps. Cheers!
There is at least one file holding a series of coordinates (Latitude, Longitude) of each of the colored lines. Get those coordinates and use Polylines. These should take care of the colored lines. The grey dots would be Markers and these could be in the same file. Assuming that GoogleMaps has similar places names, then with these two you ought to be able to reproduce the map.
I am working on a cross platform app both for android and iOS. I am using phonegap as bridge between HTML5 and android/iOS.
In my database there is multiple geo point(latitude& longitude). It is easy to show a point in the map by below
//Javascript//collecting data from database with JSON
var map = new GoogleMap();
map.initialize("map_home_location",data[0].home_lat,data[0].home_lng);
////HTML5
<div class="rhtForm" style="height:250px;" id="map_home_location"></div>
One geo location point is showing properly.
But i want to show
1) multiple geo location point in a map with short description of each point.
2) When click into a point long description will show.
here description means other information stored with specific geo location point.
Thanks in advance.
Marker newMark =
map.addMarker(new MarkerOptions()
.position(lat,lng)
.title("title")
.snippet("short desc"));
Then you have the marker you just added in an object to modify if you want. Otherwise you cab just use add marker. The title and snippet pop up on clicking the marker by default.
I am developing an application which shows the current location of the user. I want to display a marker on the current location of the user.
I have used an image as marker to display current location. But i want to display an animated arrow showing the range just like in the google maps android app. Can anyone please tell me how to achieve this. Any sample code will be of great help...
try this tricky solution...
if u use javascript, try setInterval() to cahnge image if .gif doesn't work.
function runAnimation(callback){
setInterval(function(){
// set new marker here
// var newVal = callback(); <-- use callback to get new value
}
, 500); // interval in millisec
}
