No view found for id 0x7f0a001a ( mypackage name) for fragment Maps{435e2398 #2 id=0x7f0a001a}

问题:

I am trying to open an mapsfragment from another fragement which has a list of items. When I do that I get:

 No view found for id 0x7f0a001a (com.ylg.main:id/map) for fragment Maps{435e2398 #2 id=0x7f0a001a}

what could be wrong here.

Maps.class:

public class Maps extends Fragment implements GoogleMap.OnMyLocationChangeListener {    @Override    public View onCreateView(LayoutInflater inflater, ViewGroup container,   Bundle savedInstanceState)     {      if (rootView != null)      {         ViewGroup parent = (ViewGroup) rootView.getParent();         if (parent != null)             parent.removeView(rootView);     }     try      {         rootView = inflater.inflate(R.layout.activity_maps, container, false);     }      catch (InflateException e)      {         /* map is already there, just return view as it is  */     }      fa = getActivity();       if (initMap())     {              gps = new GPSTracker(fa);             curlat = gps.getLatitude();             curlong = gps.getLongitude();             gps.stopUsingGPS();             //Get the ZOOM working for given location.     }     else     {         Toast.makeText(getActivity().getApplicationContext(),"Sorry! Map not available!", Toast.LENGTH_SHORT).show();     }       return rootView; }  private boolean initMap()  {     if (googleMap == null)     {         SupportMapFragment mapFrag = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map));         googleMap = mapFrag.getMap();         googleMap.setTrafficEnabled(true);         googleMap.setMyLocationEnabled(true);         googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);         googleMap.setOnMyLocationChangeListener(this);     }      return (googleMap != null);  }  }

My activity_maps.XML looks like this:

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/relativeLayoutforMap" android:layout_width="match_parent" android:layout_height="match_parent" >  <fragment     android:id="@+id/map"     android:name="com.google.android.gms.maps.MapFragment"     android:layout_width="match_parent"     android:layout_height="match_parent" />  </RelativeLayout>

from: Friends.class

I have list of items in this class on Item Click I am trying to open the maps fragement.

  public class Friends extends Fragment    {      View rootView = inflater.inflate(R.layout.activity_friends, container, false);      list = (ListView) rootView.findViewById(R.id.friends_list);       list.setOnItemClickListener(new OnItemClickListener()     {       @Override        public void onItemClick(AdapterView<?> parent, View view, int position, long id)          {         android.support.v4.app.FragmentManager fragmentManager = getActivity().getSupportFragmentManager();         android.support.v4.app.FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();         Maps fragment = new Maps();         fragmentTransaction.replace(R.id.map, fragment);         fragmentTransaction.commit();     }   });    return rootView; }

Can somebody help me fix this?

Thanks!
