[android-developers] Re: Displaying Google Map Android API V2 in fragment

Hi,
I have done same task, adding Map inside fragment, where fragment is placed inside ViewPager.

public class Map extends Fragment {

    /** The view. */
    private static View view;

    /** The g map. */
    private static GoogleMap gMap;

    /** The bangalore. */
    private final LatLng BANGALORE = new LatLng(12.971689, 77.594504);

    /** The zoom. */
    private float zoom = 11.0f;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        if (container == null) {
            return null;
        }

        if (view != null) {
            ViewGroup parent = (ViewGroup) view.getParent();
            if (parent != null)
                parent.removeView(view);
        }
        try {
            view = inflater.inflate(R.layout.map, container, false);
            setUpMapIfNeeded();
        } catch (InflateException e) {
            // Log.wtf("S*****", e.getMessage());
        }
        return view;
    }

    @Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        gMap = null;
        if (gMap != null)
            setUpMap();

        if (gMap == null) {
            gMap = ((SupportMapFragment) this.getActivity().getSupportFragmentManager()
                    .findFragmentById(R.id.mapd)).getMap();
            if (gMap != null)
                setUpMap();
        }
    }

    /***** Sets up the map if it is possible to do so *****/
    public void setUpMapIfNeeded() {

        if (gMap == null) {
            gMap = ((SupportMapFragment) getActivity().getSupportFragmentManager()
                    .findFragmentById(R.id.mapd)).getMap();
            if (gMap != null)
                setUpMap();
        }
    }

    /**
     * This is where we can add markers or lines, add listeners or move the
     * camera.
     * <p>
     * This should only be called once and when we are sure that {@link #gMap}
     * is not null.
     */
    private void setUpMap() {
        gMap.addMarker(new MarkerOptions().position(BANGALORE).title("My Home")
                .snippet("Home Address"));
        gMap.animateCamera(CameraUpdateFactory.newLatLngZoom(BANGALORE, zoom));
    }

    /****
     * The mapfragment's id must be removed from the FragmentManager or else if
     * the same it is passed on the next time then app will crash
     ****/
    // @Override
    // public void onDestroyView() {
    // super.onDestroyView();
    // FragmentManager fm = getActivity().getSupportFragmentManager();
    // Fragment fragment = (fm.findFragmentById(R.id.mapd));
    // FragmentTransaction ft = fm.beginTransaction();
    // ft.remove(fragment);
    // ft.commit();
    // }
}

Hi All,

I have problem in showing Google map (API V2) in fragment.

I am using ViewPager, inside that I have created my layout and also displaying map.

I have created Map dynamically using SupportMapFragment.

I have 3 pager (Fragment), all 3 fragments will showing map.

When I switch to 1st fragment to 2nd fragment at that time map is not displaying in my 2nd fragment layout. Showing black screen..... :(
