Android的碎片谷歌地圖V2：錯誤充氣類片段

Question

我正在開發它採用片段標籤的應用程序，我的片段的人使用谷歌地圖V2

public class AppMapFragment extends Fragment { 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 

    View rootView = inflater.inflate(R.layout.fragment_map, container, false); 

    try { 
     // Loading map 
     initilizeMap(); 

    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
    initializePOI(); 

    addMarkers(); 
    googleMap.setMyLocationEnabled(true); 
    googleMap.getUiSettings().setMyLocationButtonEnabled(true); 
    LocationManager locationManager = (LocationManager)getActivity().getSystemService(Context.LOCATION_SERVICE); 
    Criteria criteria = new Criteria(); 
    String provider = locationManager.getBestProvider(criteria,true); 
    Location location = locationManager.getLastKnownLocation(provider); 
    if (location!=null) { 
      double latitude = location.getLatitude(); 
      double longitude = location.getLongitude(); 
      myPos = new LatLng (latitude, longitude); 
      googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(myPos, 15)); 
    } else { 
     // Move the camera instantly to London with a zoom of 15. 
     googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(LONDON, 15)); 
    } 

    // Zoom in, animating the camera. 
    googleMap.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null); 

    return rootView; 
} 

我的xml：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical" 
android:background="#17df0d"> 

<fragment 
    android:id="@+id/map" 
    android:name="com.google.android.gms.maps.MapFragment" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"/> 

</RelativeLayout> 

我表現：

<?xml version="1.0" encoding="utf-8"?>

錯誤：

我只複製錯誤的部分，因爲它很長:(。每當我嘗試運行應用程序時都會發生此錯誤。它引用的行是View rootView = inflater.inflate(R.layout.fragment_map, container, false);。任何幫助都感激不盡！在此先感謝

看看這個實現，你應該爲你已經做了，創建一個片段，在它的地圖：

public class MapFragment extends Fragment 

創建佈局： mapview.xml：

<?xml version="1.0" encoding="utf-8"?> 
<fragment xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:map="http://schemas.android.com/apk/res-auto" 
android:id="@+id/mapview" 
android:name="com.google.android.gms.maps.SupportMapFragment" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
map:cameraZoom="12" 
map:mapType="normal" 
map:uiZoomControls="false" 
map:uiRotateGestures="true" 
map:uiScrollGestures="true" 
map:uiZoomGestures="true" 
map:uiTiltGestures="false" /> 

然後在該片段中做到這一點：

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 

    return inflater.inflate(R.layout.mapview, container, false); 
} 

然後拿到地圖實例：

private GoogleMap getGoogleMap() { 
     if (map == null && getActivity() != null && getActivity().getSupportFragmentManager()!= null) { 
      SupportMapFragment smf = (SupportMapFragment)getActivity().getSupportFragmentManager().findFragmentById(R.id.mapview); 
      if (smf != null) { 
       map = smf.getMap(); 
      } 
     } 
     return map; 
    }
