Basing on the code given here my app implements the Google Maps V2. The problem is that I have this fragment-based menu (sorry if I misspelled the concept) that gets overlayed by the Google Maps fragment after a very short time.
Is it possible to make the Google Maps fragment to stay in the back of the menu fragment?
Map code:
public class AdMapFragment extends Fragment
{
MapView mMapView;
private GoogleMap googleMap;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// inflat and return the layout
View v = inflater.inflate(R.layout.activity_ad_map, container,
false);
mMapView = (MapView) v.findViewById(R.id.mapView);
mMapView.onCreate(savedInstanceState);
mMapView.onResume();// needed to get the map to display immediately
try {
MapsInitializer.initialize(getActivity().getApplicationContext());
} catch (Exception e) {
e.printStackTrace();
}
googleMap = mMapView.getMap();
// latitude and longitude
double latitude = 17.385044;
double longitude = 78.486671;
// create marker
MarkerOptions marker = new MarkerOptions().position(
new LatLng(latitude, longitude)).title("Hello Maps");
// Changing marker icon
marker.icon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_ROSE));
// adding marker
googleMap.addMarker(marker);
CameraPosition cameraPosition = new CameraPosition.Builder()
.target(new LatLng(17.385044, 78.486671)).zoom(12).build();
googleMap.animateCamera(CameraUpdateFactory
.newCameraPosition(cameraPosition));
return v;
}
@Override
public void onResume() {
super.onResume();
mMapView.onResume();
}
@Override
public void onPause() {
super.onPause();
mMapView.onPause();
}
@Override
public void onDestroy() {
super.onDestroy();
mMapView.onDestroy();
}
@Override
public void onLowMemory() {
super.onLowMemory();
mMapView.onLowMemory();
}
}
I made activities to work this way - they are just extending the MenuActivity so there is only one central activity for menu. Activity code
public class AdMapActivity extends MenuActivity
{
}
MenuActivity refers to caller class and aggregates the request. Menu code
public class MenuActivity extends Activity
{
private DrawerLayout menuLayout;
private ListView menuList;
private ActionBarDrawerToggle menuToggle;
private ArrayList<MenuListItem> menuItems;
private MenuListItemAdapter menuAdapter;
private ArrayList<BasicNameValuePair> fragmentsMenu;
private ArrayList<String> fragmentsMenuClass;
private ArrayList<String> fragmentsMenuName;
private ArrayList<Integer> fragmentsMenuIcon;
private HashMap<String, String> fragmentsIndividual;
private void displayView(int position)
{
String className = fragmentsMenuClass.get(position);
try
{
Fragment fragment = (Fragment) Class.forName(getPackageName() + '.' + className.substring(0, className.length() - 8) + "Fragment").newInstance();
if (fragment != null)
{
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.frame_container, fragment).commit();
menuList.setItemChecked(position, true);
menuList.setSelection(position);
menuLayout.closeDrawer(menuList);
}
}
catch (Exception e)
{
Log.e("error", Log.getStackTraceString(e));
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu, menu);
return super.onCreateOptionsMenu(menu);
}
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_menu_list);
fragmentsMenuClass = new ArrayList<String>();
fragmentsMenuClass.add("AdListActivity");

menuItems = new ArrayList<>();
for (int i = 0; i < fragmentsMenuClass.size(); i++)
{
menuItems.add(new MenuListItem(String.valueOf(fragmentsMenuName.get(i)), (Integer) fragmentsMenuIcon.get(i)));
}
menuList = (ListView) findViewById(R.id.menu_list);
menuList.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
displayView(position);
}
});
menuAdapter = new MenuListItemAdapter(getApplicationContext(), menuItems);
menuList.setAdapter(menuAdapter);
menuLayout = (DrawerLayout) findViewById(R.id.menu_layout);
menuToggle = new ActionBarDrawerToggle(this, menuLayout, R.drawable.global_button_like_image, R.string.app_name, R.string.app_name)
{
public void onDrawerClosed(View view)
{
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView)
{
invalidateOptionsMenu();
}
};
menuLayout.setDrawerListener(menuToggle);
final String className = getClass().getSimpleName();
if (savedInstanceState == null)
{
if (fragmentsMenuClass.contains(className))
{
displayView(0);
}
else
{
try
{
Fragment fragment = (Fragment) Class.forName(getPackageName() + '.' + className.substring(0, className.length() - 8) + "Fragment").newInstance();
FragmentManager fragmentManager = getFragmentManager();
fragment.getView().bringToFront();
fragmentManager.beginTransaction().add(R.id.frame_container, fragment).commit(); //replace -> add
}
catch (Exception e)

Log.e("error", Log.getStackTraceString(e));
