I want to override the method enableMyLocation() in MyLocationOverlay class, in order to implement my own positioning algorithm to get latitude/longitude, and then plot them onto a MapView. I figured out how to do that, but now I'm stuck because I dont know what Canvas to pass when I call the method drawMyLocation().
Here is the MyLocationOverlay class

I've found bits and pieces of this answer scattered through other posts, but I wanted to record it here for others.How can I simply request the user's GPS and/or Network location and, if they haven't enabled the service, prompt them to do so?
View 1 Replies View RelatedI am building a MapView and I want my custom overlay items to display the name of the location they are marking when the user taps them, like the Android Maps app. I setup the onTap listener and the floating TextView to hold the location name. I still need to set it up so that it redraws the label when the user moves the map, etc. Anyway, I am wondering if I am reinventing the wheel here. Is there a built-in method I am unaware of? I would think that most implementations of MapView have labels. For reference, my implementation so far: in map xml:
<LinearLayout android:id="@+id/mapBubbleWrap" android:layout_width="wrap_content"
andoid:layout_height="wrap_content" android:layout_alignParentTop="true">
<TextView android:id="@+id/mapBubble" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:visibility="gone"
android:background="#ffffff" android:textColor="#ff0000"/>
</LinearLayout>
in my extended ItemizedOverlay:
public boolean onTap(int index) { this.setFocus( mOverlays.get(index) ); return true; }
in my Activity onFocus:
public void onFocusChanged( ItemizedOverlay overlay, OverlayItem item ) {
if( item != null) { mapBubble.setText(item.getTitle());
Point newPoint = mapView.getProjection().toPixels(item.getPoint(), null);
mapBubbleWrap.setPadding(newPoint.x, newPoint.y-10, 0, 0);
mapBubble.setVisibility(View.VISIBLE); } }
I am trying to see if anyone knows if it is possible to change the update time of MyLocationOverlay (http://bit .ly /dBIVdj). I have tried subclassing MyLocationOverlay and implementing my own location manager but when that happens I do not see the overlay on the map. I would try overriding the drawMyLocation method however I don't know which canvas to provide the method (since I would be drawing onLocationChange). To summarize, I am looking to do three things in MyLocationOverlay subclass:
1. Change the location update times to whatever I want.
2. Draw the "my location" dot with the radius when the onLocationChanged() method is called.
I've thought about making my own special class with special overlay -- but I feel like there has to be a better method to get what I want out of this class.
I want to use my image to replace the Compass image of MyLocationOverlay, how can i implement?
View 1 Replies View RelatedI am trying to implement the MyLocationOverlay class from google maps. However, when I try and use my own locationManager -- I cannot get the overlay to acutally draw on the map. I am wondering if I am doing something wrong.
I don't want to call the super method(enbaleMyLocation) of the MyLocationOverlay class because that request updates from the locationManager way too quickly and will eat my battery alive.
Here is my code...
I am using these three lines to add a compass on the MapView: mMyLocationOverlay = new MyLocationOverlay (this,mapView);mMyLocationOverlay. enableCompass(); mapView.getOverlays() .add(mMyLocation Overlay) ; However the default position of the compass showing on the screen is not too good for my apps, and I want to move it to somewhere else. Anyone knows how I can achieve that?
View 2 Replies View RelatedI'm messing around with maps and gps and i have some questions. Hope any of you point me in the right direction:
- I´m loading about 400 overlays in a mapview, but it takes 2-3 minutes. Is there any way to speed things up?
- On the other hand, I use another overlay to point device gps position, but when location point change i need to delete this overlay to put it again in it's new position. How can i delete this overlay without deleting all the others?
I have an activity that has a button which opens a new MapActivity to select a location by tapping on the map.
The map has an overlay that overrides the onTap method to get the location but I want to return that location to the previous activity but, I don't know how to return the geopoint to the mapactivity in order to call the setResult() and finish() methods, because I can't call them from the Overlay.onTap method.
I'd like to write a simple widget that toggles GPS and network location on and off. I've read that it's not possible to do that normally, but presumably on a rooted phone it must be doable. Does anyone know what the code would be? (I only need the code to toggle the location providers, I know how to make the widget.) It doesn't matter that this isn't a 'good' solution, I don't plan to distribute the widget. If it matters, this would be on an HTC Hero, still running v1.5.
View 1 Replies View RelatedI'm developing a mapping app using Eclipse 3.5.I'm setting the minimum update period with the LocationManager's requestLocationUpdates method, via a configuration activity. When I set the property I see in Logcat that the system process sets the value OK.When I actually send a new location from the DDMS emulator control and the location changes on the map view, I see that the system process then sets the minimum time to zero.Below is a capture of the system's log messages. You can see that I'm setting the period to 32 seconds, then 16, then, after I've sent a simulated location change the system sets it to zero.The map responds to location changes to location changes instantly even if they are sent only a couple of seconds apart.
View 1 Replies View RelatedIn my application I have to fetch the current location. First it correctly fetches the location. But we are moving from the current location to some other location. It shows the previous address. It is not updating the location. My code is: locManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE); locListener = new MyLocationListener();locManager.requestLocationUpdates(LocationManager .GPS_PROVIDER ,0,0,locListener); location = locManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);if(location != null){latitude = location.getLatitude();longitude = location.getLongitude();} Please find the mistake and when i launch first time it is not working on second time itself it is working so check this thing also.
View 1 Replies View RelatedI have an application which uses the network as the location provider (rather than GPS eg.), however I can't seem to figure out how to send the emulator test coordinates. In DDMS I would usually send coordinates in the Emulator Control tab.Is there a place to simulate coordinates derived from the cell phone network provider?

View 5 Replies View RelatedRecently all my android devices think they are in Spain when I am at home in Toronto.
I think this was caused when I ran a location spoofing program on only one of my devices, one of the locations I set it to was Spain (among others).
I've tried clearing the data for the Network Location apps, changing the SSID on my router with no luck.
The only way it shows the correct location is when I go outside and run Google maps long enough to get a GPS fix. But when I go back inside I am back in Spain!

The way we are retrieving locations from our Android phones is to 1st get a Coarse Location followed by a Fine Location. This is for the case where the user may be inside a building initially and unable to track satellites. After we get our coarse location we transition to a fine location to track satellites. This method has been working fine for several months. We recently upgraded to 1.5 and our mapping application, to my recollection continued to work.For the past couple of days we have not been able to get a coarse location and we are receiving a status message in the onStatusChange callback of.We have re- installed previous versions our code that used 1.1 and we are receiving the same status message of .TEMPORARILY_UNAVAILABLE. Other than the obvious description of the constant, we can find no meaningful information.
View 2 Replies View RelatedHow could I fix the location which appears on the clock on the home screen and serves as weather forecast location? I am not living near a big city listed on the weather location list and when at home, the current location usually is indicated some dozen miles away from my home. This could be a cosmetic problem, but in the Alps (where I am living) weather a short distance away can be quite different from where you are.
Besides that, it would be nice to know the weather at home while beeing abroad.
i've had my phone about 3 weeks now. up until last week, the htc weather widget would update to my current location. when i was home, it would show the town i live in. i also had the google internet option to use my location and this would also work perfectly until last sunday.now, the weather location was stuck on miami no matter where i went (as far north as west palm beach) and the internet shows up 'location unavailable'. i have found out that the gps is picking up where i am in goggle maps but it seems that the cell towers are not as far as weather and internet location are concerned. i have tried all of the obvious settings.i did a factory reset and now my weather says ft lauderdale which is closer to me but still not my town. it does not update (manually either) as i move. the internet location still says location unavailable although for a fleeting minute after the factory reset, it DID locate me....then it was gone so i called verizon, they didn't have a clue. then i took it to the store and it turns out EVERY phone the tech tried in the store had the same problem, including his. he told me it was a google problem and there was nothing he could do about it. i felt if i tried explaining how that would make it a verizon problem as well, it would be a losing battle
