I have a project using OSMDroid. There is a loop that draws markers, end after that I have to center map at a certain marker. My code:
//I have on open Cursor c
Marker switchTo = null;
do {
Marker mr = new Marker(mapView);
GeoPoint gp = new GeoPoint(c.getDouble(iLat), c.getDouble(iLng));
mr.setPosition(gp);
//some actions: set anchor, drawable etc
int id = c.getInt(iId);
if (MainActivity.switchToId != -1 && id == MainActivity.switchToId) {
switchTo = mr; //if I have to switch to exactly this marker
MainActivity.switchToId = -1; //cleanup
}
mPoiMarkers.add(mr); //add to cluster
} while (c.moveToNext()); //next marker
mapView.getOverlays().add(mPoiMarkers); //add cluster to map
Log.d(TAG, "Markers redrawed.");
if (switchTo != null) { //go to marker
mapView.getController().setCenter(switchTo.getPosition());
mapView.getController().setZoom(14);
}
The problem: map sets centre not at a marker, but in some kilometres from it. I don't know what's going on. Marker stands at its normal place...
The true way is to set centre after setting zoom.
mapView.getController().setZoom(15);
mapView.getController().setCenter(sw);
