解决方案
请您Aparment类实现序列化：
公共类公寓实现Serializable {
然后在 MyMapOverlayIcon ：
叠B =新包（）;
// 该怎么办！？
b.putSerializable（公寓，AP）;
然后在 ApartmentInfoActivity ：
公寓AP =（公寓）getIntent（）getSerializableExtra（公寓）。
I've tried many different solutions found here and many other sites - but i just can't make it work!
I have an object "Apartment" in one activity which is to be used in another activity.The activity is started from the class MyMapOverlayItem and should start the ApartmentInfoActivity in which the Apartment object should be used.

}
public MyMapOverlayIcon(Drawable defaultMarker, Context context, ArrayList<Apartment> myList) {

mContext = context;
this.myList = myList;
}
public void addOverlay(OverlayItem overlay) {
mOverlays.add(overlay);
populate();
}
@Override

解决方案
Make your Aparment class implement Serializable:
public class Apartment implements Serializable{
Then on MyMapOverlayIcon:
Bundle b = new Bundle();
// WHAT TO DO!?
b.putSerializable("apartment", ap);
Then on ApartmentInfoActivity:
Apartment ap = (Apartment) getIntent().getSerializableExtra("apartment");
