Re: [android-developers] Driving directions in Google map view

The Android framework comes with XML and JSON parsers. Searching for "android xml parser" or "android json parser" should turn up helpful results. There's nothing builtin to parse directions specifically, but it shouldn't be hard once you've got the XML or JSON parsed. Steve On Wed, Aug 11, 201

Re: [android-developers] Direction information in android MapView

Your best bet is to use the Google Directions API, which is a generic web service for directions info. You'll have to do a lot of the glue work yourself though (reading the directions and painting a path onto the MapView), unfortunately, unless you come across a good third-party library (I don't k

The zoom may be deferred if the MapView hasn't been drawn yet. Have you tried putting your logic in a Runnable and post()ing it to the MapView? Steve On Sun, Aug 29, 2010 at 7:18 PM, Chad McQuillen wrote: > My application has a MapView which shows a collection of items in a > satellite view. I

An easy way to accomplish this is to use an Overlay. Something like this: class MyOverlay extends Overlay { public boolean onTap(GeoPoint point, MapView mapView) { // do something with point } } And elsewhere: MyOverlay overlay = new MyOverlay(); myMapView.getOverlays().add(overlay); Y

Re: [android-developers] Google Maps API: Catching zoom and panning events

A simple solution is to add an Overlay, override the draw() method, and not actually do any drawing, but simply use the method as a hook to know anytime the map has potentially moved or zoomed. The problem is, this will get called more often than necessary, so you'll need some custom logic to deci

Re: [android-developers] Auto zoom to fit markers on an overlay

Are you using ItemizedOverlay to display your markers? If so, ItemizedOverlay.getLatSpanE6() and ItemizedOverlay.getLonSpanE6() will give you the span of your markers. You can then use MapController.zoomToSpan() to find an appropriate zoom level. As for panning, depending on your application, yo

I think the ideal usage would be something like this: public boolean onTap(GeoPoint point, MapView mapView) { // first, let the superclass check if the event hit a marker; if so, it'll call onTap(index) // if it returns true, that means onTap(index) returned true, meaning the event has been ha

Re: [android-developers] Re: ItemizedOverlay.hitTest incorrect

As explained in your other email thread, it should not be necessary to call hitTest manually for this purpose. However, for the record, I believe the problem here is that hitTest() takes the hit point in coordinates relative to the marker, not in absolute screen coordinates. This is vaguely descr

Re: [android-developers] ItemizedOverlay & database items: When do I update the OverlayItem list?

I think some of the confusion might be coming from the fact that you're expecting too much high-level logic from ItemizedOverlay. ItemizedOverlay is a pretty basic class. You override size() and createItem() to do whatever you want, and then you call populate() anytime you want to update the item
