Your description of the problem is somewhat vague... do you mean you want to be able to use device GPS to locate yourself on map?
You need to use LocationDisplayManager - here is some code from my app
// In case you need it later, make it class variable
LocationDisplayManager lDisplayManager = null;
// ... inside onCreate(), after your .addlayers
mMapView.setOnStatusChangedListener(new OnStatusChangedListener() {
@Override
public void onStatusChanged(Object source, STATUS status) {
if (source == mMapView && status == STATUS.INITIALIZED) {
lDisplayManager = mMapView.getLocationDisplayManager();
lDisplayManager.setAutoPanMode(LocationDisplayManager.AutoPanMode.LOCATION);
lDisplayManager.setLocationListener(new LocationListener() {
boolean locationChanged = false;
// Zooms to the current location when first GPS fix arrives.
@Override
public void onLocationChanged(Location loc) {
if (!locationChanged) {
locationChanged = true;
double locy = loc.getLatitude();
double locx = loc.getLongitude();
Point wgspoint = new Point(locx, locy);
Point mapPoint = (Point) GeometryEngine
.project(wgspoint,
SpatialReference.create(4326),
mMapView.getSpatialReference());
Unit mapUnit = mMapView.getSpatialReference()
.getUnit();
double zoomWidth = Unit.convertUnits(
5,
Unit.create(LinearUnit.Code.MILE_US),
mapUnit);
Envelope zoomExtent = new Envelope(mapPoint,
zoomWidth, zoomWidth);
mMapView.setExtent(zoomExtent);
}
}
@Override
public void onProviderDisabled(String arg0) {
}
@Override
public void onProviderEnabled(String arg0) {
}
@Override
public void onStatusChanged(String arg0, int arg1,
Bundle arg2) {
}
}); // Actionlistener
lDisplayManager.start();
}
}
}
if (source == mMapView && status == STATUS.LAYER_LOADED) {
}
}
}
});
There might be some extra } or { as I copy pasted it from the code and had to remove some special stuff related to our app.
HTH.
