I want to add markers to my OSMdroid map. I am using OSMdroid version 5.5. The official tutorial suggests the following code:
//your items
ArrayList<OverlayItem> items = new ArrayList<OverlayItem>();
items.add(new OverlayItem("Title", "Description", new GeoPoint(0.0d,0.0d))); // Lat/Lon decimal degrees
//the overlay
ItemizedOverlayWithFocus<OverlayItem> mOverlay = new ItemizedOverlayWithFocus<OverlayItem>(items,
new ItemizedIconOverlay.OnItemGestureListener<OverlayItem>() {
@Override
public boolean onItemSingleTapUp(final int index, final OverlayItem item) {
//do something
return true;
}
@Override
public boolean onItemLongPress(final int index, final OverlayItem item) {
return false;
}
}, mResourceProxy); // <----- where to get this object from?
mOverlay.setFocusItemsOnTap(true);
mMapView.getOverlays().add(mOverlay);
However, I don't know where to get the mResourceProxy
object from. All websites I found about this topic (including OSMdroid's GitHub page) are making use of the DefaultResourceProxyImpl
class, which is deprecated since version 5.2.
Does anyone know how to add marker versions >= 5.2?
Okay, so I found out how to use it. The ItemizedOverlayWithFocus
doesn't require a ResourceProxy at all. So you can use one of the following constructors:
public ItemizedOverlayWithFocus(Context pContext, List<Item> aList, OnItemGestureListener<Item> aOnItemTapListener) { ... }
public ItemizedOverlayWithFocus(List<Item> aList, OnItemGestureListener<Item> aOnItemTapListener, Context pContext) { ... }
public ItemizedOverlayWithFocus(List<Item> aList, Drawable pMarker, Drawable pMarkerFocused, int pFocusedBackgroundColor, OnItemGestureListener<Item> aOnItemTapListener, Context pContext) { ... }
This is how I adjusted the code from my question to make it work:
//your items
ArrayList<OverlayItem> items = new ArrayList<OverlayItem>();
items.add(new OverlayItem("Title", "Description", new GeoPoint(0.0d,0.0d))); // Lat/Lon decimal degrees
//the overlay
ItemizedOverlayWithFocus<OverlayItem> mOverlay = new ItemizedOverlayWithFocus<OverlayItem>(
this, items, // <--------- added Context this as first parameter
new ItemizedIconOverlay.OnItemGestureListener<OverlayItem>() {
@Override
public boolean onItemSingleTapUp(final int index, final OverlayItem item) {
//do something
return true;
}
@Override
public boolean onItemLongPress(final int index, final OverlayItem item) {
return false;
}
}); // <----- removed the mResourceProxy parameter
mOverlay.setFocusItemsOnTap(true);
mMapView.getOverlays().add(mOverlay);
