osmdroid

问题 All I have used osmdroid and i want to download map zip files from android app and than create offline map. Any one have more knowledge about osmdroid and offline map and navigation. 回答1: The easisest way is to download MOBAC, then run it and mark out an area you want, store the tiles in Osmdroid.zip format. When that's done, drop the zip file into the osmdroid folder on your device. 回答2: First of all you need to download Mobile Atlas Creator. This link is for the latest version of MOBAC 1-

问题 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);

问题 I've written a mapping application which has two activities, one activity displays a Google Maps view, the other displays the equivalent view using osmdroid 3.0.5 jar. Until now I've been testing on emulators only and the functionality is completely identical in terms of area shown and overlay data. Now I have run the app on a real Gingerbread device, I notice that the Google Maps activity seems to support pinch to zoom, whilst the Osmdroid one doesn't. I haven't written any code specific to

问题 I'm using osmdroid on my new Android project (since I want to be able to use offline maps) but I encounter many difficulties to customize the look 'n feel of the information bubble assigned to an overlay item. Right now, I'm using an ItemizedOverlayWithFocus overlay to display my items; looking at its code, I noticed the whole thing was drawn in the onDrawFinished method so I tried to create my own custom overlay to override this method but this is pretty difficult to get a result. What I

问题 Been wanting to display just one section of the world map. Made mbtiles for it as well. But I also want the user to not be able to move outside a limited area. Below is the code I ran using Bounding Box on the world map but nothing is displayed on the screen, both on an emulator and an actual android device. Please help.

问题 I've this snippet of code which I would like to optimize it. I've a method which is been called regularly by the OSMdroid library to load tons of maptiles. This method directly invokes the filestream and load the bitmap directly and will return the bitmap once loaded on the main UI thread. Although I've managed to run in the background using AsyncTask with parallel executor. Sometimes with plenty number of overlays (itemized) in the mapview this snippet of code runs slower as GC_FO_ALLOC is

问题 I'm using osmdroid 5.2 lib in android 6.0 . I'm asking WRITE_EXTERNAL_STORAGE and ACCESS_COARSE / FINE_LOCATION permissions on realtime .

Can anyone help me? Thanks in advance. 回答1: You have to ask for the permissions before the mapview is loaded and displayed.

问题 I notice that it seems impossible to use the CacheManager with the tiles source MapQuest, it receives http code 202 and doesn't download the tiles. Do you know why? 回答1: Just ran across on this on the osm mailing list MapQuest is moving to a 100% cloud solution - the new infrastructure dictates that all tile access will require a key. Details on how to get keys, SDKs and general migration information is below: On Monday, July 11, 2016, our direct tile access to MapQuest legacy maps will be

问题 I'm using OSMdroid Mapview and using AsyncTask class to get some data, and I create overlays and try to redraw every time I get a msg. Unfortunately I'm able to get data from a client and I'm able to create overlays to in onProgressUpdated , I've even called invalidate(); But nothing seems to happen. Not sure what is the problem?
