Open map with current city where i am and navigation map
Hello jaak,
1. After the login in our app ,i want the map come with our current city or current location where i am
2. when i click on current location it will show my location but we can't navigate the map
"The below code i use for current location"
if (System.getProperty("microedition.location.version") != null)
{
final LocationSource dataSource = new LocationAPIProvider(3000);
try
{
final Image gpsPresentImage = Image.createImage("/gps_marker_green.png");
final Image gpsConnectionLost = Image.createImage("/gps_marker_brown.png");
final LocationMarker marker = new NutiteqLocationMarker(new PlaceIcon(gpsPresentImage, 4, 16), new PlaceIcon(gpsConnectionLost, 4, 16), 3000, true);
dataSource.setLocationMarker(marker);
mapComponent.setLocationSource(dataSource);
}
catch (final IOException e)
{
}
}
so can you tell me how i achieve this two task please reply me as soon as possible
Hello jaak,
I use below code to navigate the map but i still face the same problem
please provide your suggesstion
if (System.getProperty("microedition.location.version") != null)
{
final LocationSource dataSource = new LocationAPIProvider(3000);
try
{
final Image gpsPresentImage = Image.createImage("/gps_marker_green.png");
final Image gpsConnectionLost = Image.createImage("/gps_marker_brown.png");
final LocationMarker marker = new NutiteqLocationMarker(new PlaceIcon(gpsPresentImage, 4, 16), new PlaceIcon(gpsConnectionLost, 4, 16), 3000, true);
dataSource.setLocationMarker(marker);
mapComponent.setLocationSource(dataSource);
dataSource.addLocationListener(new LocationListener()
{
public void setLocation(WgsPoint p)
{ marker.updatePosition();
mapComponent.setLocationSource(dataSource);
}
});
}
catch (final IOException e)
{
}
}
Probably what happens here is that you get recentered with every GPS measurements, so if user navigates map away, it will jump back automatically. You should make sure that if map is recentered with "My location" only once, unless user really wants to get "automatic gps tracking". I know it could be a bit tricky to get properly working.

Thanks Jaak for your suggestion
LocationSource (dataSource in your case) has method addLocationListener(LocationListener). So you should implement a LocationListener class and add it to your dataSource. then LocationListener method setLocation(WgsPoint) which will get location updates. In this method you can call map.setMiddlePoint(WgsPoint) to recenter map with the first received location fix. Note: this fix could take some time, even few minutes (depending on satellite visibility etc).
