SupportMapFragment on DialogFragment

Question

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:

enter image description here

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.

Is there anything wrong shown in the logcat? – dumbfingers Jun 06 '13 at 13:49 — dumbfingers, Jun 06 '13 at 13:49

You can show a map fragment in a dialog by this

public class DialogMapFragment extends DialogFragment {

    private SupportMapFragment fragment;

    public DialogMapFragment() {
        fragment = new SupportMapFragment();
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.mapdialog, container, false);
        getDialog().setTitle("");
        FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
        transaction.add(R.id.mapView, fragment).commit();

        return view;
    }



    public SupportMapFragment getFragment() {
        return fragment;
    }
}

R.layout.mapdialog:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="0dp" >

    <FrameLayout
        android:id="@+id/mapView"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
    </FrameLayout>

</RelativeLayout>

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.
