解决方法
Here is a book’s sample application显示了如何在API Level 11应用程序中的片段中使用MapView.它主要只是一个MapActivity.以下是加载MapView的片段的关键位：
public class MapFragment extends Fragment {
private MapView map=null;
private MyLocationOverlay me=null;
@Override
public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
return(new FrameLayout(getActivity()));
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
map=new MapView(getActivity(),"0mjl6OufrY-tHs6WFurtL7rsYyEMpdEqBCbyjXg");
map.setClickable(true);
map.getController().setCenter(getPoint(40.76793169992044,-73.98180484771729));
map.getController().setZoom(17);
map.setBuiltInZoomControls(true);
Drawable marker=getResources().getDrawable(R.drawable.marker);
marker.setBounds(0,marker.getIntrinsicWidth(),marker.getIntrinsicHeight());
map.getOverlays().add(new SitesOverlay(marker));
me=new MyLocationOverlay(getActivity(),map);
map.getOverlays().add(me);
((ViewGroup)getView()).addView(map);
}
// rest of fragment here
}
