itemizedoverlay

I have a map view with thousand of items that i want to load on it. obviously i can't load them all when the view is created. I guess that I have to load them asynchronously according to what is currently displayed.. How can I load only items located in the map portion displayed on the screen? Use AsyncTask to load the individual layers per screen. Get the Lat/Long of the currently visible map using MapView api. On the backend send them the lat/long bounding box to get the items you want. So roughly from memory it would be something like: public class LoadMapItems extends AsyncTask<Integer

I have been able to use "MapActivity" and "ItemizedOverlay" to draw overlays on google maps on android with Eclipse. But when the map is zooming in and out, the overlay does not change size. I want the overlay to be "fixed" on the map, and zoom in and out along with the map. How can this be done? I can't find the tutorial to define a boundary (e.g. with GPS coordinates as corners for the overlay image). Please provide links if you know some. and any other ways of doing it? Many thanks. Yes, there is. I had the same issue with my application. Here's an example and it works perfectly. The circle

I'm using ItemizedOverlay to display points of events on a map. My main goal is to be able to find an event that was added earlier so that I can delete (or edit) just it without clearing the whole itemizedOverlay. So I decided to add each event to the ArrayList using its own unique ID as an index. This is the code where I add the event. myItemizedOverlay itemizedOverlay = new MyItemizedOverlay(drawable, mapView); OverlayItem overlayItem = new OverlayItem(geoPoint, title, subtext); itemizedOverlay.addOverlay(overlayItem, event_id); mapOverlays.add(itemizedOverlay); This is the ArrayList and

i am develpoing a map application with osm. i want to create some marker on my mapview. im using the folowwing code: this.mMyLocationOverlay = new ItemizedOverlay<OverlayItem>(this, items, new ItemizedOverlay.OnItemGestureListener<OverlayItem>() { @Override public boolean onItemSingleTapUp(final int index, final OverlayItem item) { Toast.makeText( SampleWithMinimapItemizedoverlay.this, "Item '" + item.mTitle + "' (index=" + index + ") got single tapped up", Toast.LENGTH_LONG).show(); return true; // We 'handled' this event. } @Override public boolean onItemLongPress(final int index, final

I am using ItemizedIconOverlay class and I'm currently displaying events on the map along with the user's position with the same default icon. How do I change the icon set for each overlay? Is there something similar to the google.maps example: drawable = getResources().getDrawable(R.drawable.marker); drawable3 = getResources().getDrawable(R.drawable.disruption); drawable2 = getResources().getDrawable(R.drawable.marker_me); itemizedOverlay = new MyItemizedOverlay(drawable, mapView); itemizedOverlay2 = new MyItemizedOverlay(drawable2, mapView); itemizedOverlay3 = new MyItemizedOverlay(drawable3

I'm working on an application that displays the location of moving items on a Google MapView. I need a way to update the position of the icons that represent the items (as well as change the facing of the icons every two seconds as updated data comes in). I currently have an activity in the app that extends MapActivity. On to this I have overlaid a static Overlay that draws some lines on the map and an ItemizedOverlay that draws a static icon. There is a draw() method that claims to be used by animated overlays, but overriding it to do my animations still doesn't make anything animate. Do I

I cannot figure out the origin of the ConcurrentModificationException . In my activity I'm calling updateMapOverlay() . I'm also calling updateMapOverlay() inside another Thread (a TimerTask ) that is invoked on regular intervals. I'm taking the appropriate locks when invoking updateMapOverlay() from both the threads. Is this problem being caused because I'm invoking updateMapOverlay from inside a non-UI thread (i.e., TimerTask ). Has anyone else faced a similar issue ? private void updateMapOverlay() { this.itemizedOverlay.refreshItems(createOverlayItemsList()); List<Overlay> overlays =
