Google Maps - Fokus setzen?

Zaidy · 2011-01-28T13:30:32+0100

hallo

ich habe für mein android app eine google map erstellt. das funktioniert alles einwandfrei. nun wird aber sobald ich die map starte amerika gezeigt, jedoch befinden sich meine punkte alle in europa, daher wäre es besser wenn der focus gleich auf europa liegen würde.
kann man den focus irgendwie auf europa bzw. auf bestimmte punkte setzen?
ich habe leider nichts gefunden.

Zum Beispiel so. Hier werden im Startintent koordinaten übergeben, und auf den Punkt mit Stufe 16 gezoomt. Zusätzlich wird hier noch ein "Fähnchen" (=Stechnadel) angezeigt.
