和它的作品如预期。

I need to embed aSupportMapFragmentin aDialog. This is the best I could think of:

public class SupportMapFragmentDialog extends DialogFragment {

    private final SupportMapFragment fragment;

    public SupportMapFragmentDialog() {
        fragment = new SupportMapFragment();
        setTargetFragment(fragment, 1);
    }

    @Override
    public View onCreateView(final LayoutInflater inflater,
            final ViewGroup container, final Bundle savedInstanceState) {
        return fragment.onCreateView(inflater, container, savedInstanceState);
    }

    public SupportMapFragment getFragment() {
        return fragment;
    }

}

However, when I call this:

final SupportMapFragmentDialog dialog = new SupportMapFragmentDialog();
dialog.show(getSupportFragmentManager(), "Historico");

I get this:

What can I do to see the map on the Dialog?

The app has another SupportMapFragment that is working wonders, so it doesn't have anything to do with the configuration.

In the end I ended up usingMapViewin a regularDialoginstead ofSupportMapFragment

This is my code:

final Historico h = adapter.getItem(arg2 - 1);
if (mv.getParent() != null) {
    ((ViewGroup) mv.getParent()).removeView(mv);
}
final Dialog d = new Dialog(HistorialScreen.this);
d.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
d.requestWindowFeature(Window.FEATURE_NO_TITLE);
d.setContentView(mv);
mv.getMap().clear();
mv.getMap().moveCamera(CameraUpdateFactory.newLatLngZoom(h.getPosicion(), 17));
final MarkerOptions options = new MarkerOptions();
options.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_CYAN));
options.position(h.getPosicion());
mv.getMap().addMarker(options);
d.show();

And it works as intended.
