itemizedoverlay

I am trying to programmatically draw a parking icon to place as the drawable for an itemized overlay on a map. The icon consists of a blue square with a white 'P' in its centre of which I would like to programmatically change the colour of the square to denote different parking types. I've tried creating it via the canvas using drawRect & drawText but I cannot find a simple way of centering the text in the square and I cannot find a way to center the canvas on the coordinates - it keeps wanting to anchor from the top left hand corner. I've alternatively tried creating an XML layout to convert

Bit of a strange post as this is something I posted before, thought it was solved but didn't! I have a situation where I need to use a custom Drawable for each marker, the effect I need is to rotate the marker by a set number of degrees and am probably going the wrong way about this completely. As a start I am using the excellent Creative Commons as this does work and only breaks after my additions! https://github.com/commonsguy/cw-advandroid/tree/master/Maps/NooYawkAsync The previous post and the code is here Android Maps NullPointerException ItemizedOverlay If anyone can recommend a better

I'm building a map with a few dozen OverlayItems in a single ItemizedOverlay. My map is made to be viewed very close up (about zoom level 18+), with the OverlayItems in very close proximity to one another. The map looks good when zoomed in. However, if the user zooms out the icons begin to overlap and everything looks incredibly junky. Is there a way to control the OverlayItem icon size so that it scales with the map? If not, is there a way to hide the icons once a specific zoom level is reached? Any other suggestions on how to approach this problem? Joshc, fegruior, You folks may want to

I have a class : class MapItemizedOverlay extends com.google.android.maps.ItemizedOverlay<OverlayItem> { private Context context; private ArrayList items = new ArrayList(); public MapItemizedOverlay(Context aContext, Drawable marker) { super(boundCenterBottom(marker)); context = aContext; } public void addOverlayItem(OverlayItem item) { items.add(item); populate(); } @Override protected OverlayItem createItem(int i) { return (OverlayItem) items.get(i); } @Override public int size() { return items.size(); } @Override protected boolean onTap(int index) { OverlayItem item = (OverlayItem) items

I have the following code to add an Overlay myMapView.getOverlays().add(sites); myMapView.invalidate(); I also have the following remove code where sites is a global variable. if (sites != null) { // myMapView.getOverlays().clear(); myMapView.getOverlays().remove(sites); myMapView.invalidate(); sites = null; } Sometimes I am left with duplicates so would like a way to remove all overlays from a map, is this possible? Looks like I did have the answer all along! myMapView.getOverlays().clear() 来源： https://stackoverflow.com/questions/3696415/remove-all-overlays
