androidフラグメントのMapView

MapViewの中にFragmentを入れたい

これは私のFragmentLayout xmlファイルです

<?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:background="#17df0d"
    Android:orientation="vertical" >

<com.google.Android.gms.maps.MapView
    Android:id="@+id/mapview"
    Android:layout_width="wrap_content"
    Android:layout_height="wrap_content"
    Android:layout_above="@+id/textView1"
    Android:layout_alignParentLeft="true"
    Android:layout_alignParentRight="true"
    Android:layout_marginBottom="70dp" >

</com.google.Android.gms.maps.MapView>
</RelativeLayout>

僕の AndroidManifest.xmlファイル

    Android:versionCode="1"

と私のフラグメントクラス

public class ReportFragment extends Fragment implements LocationListener {
    MapView mapView = null; //eventually it is being read from view and assigned

アプリを起動しても、フラグメントにマップビューが表示されません

GitHubでのジョシュホルツの例 ：

MapViewにLayoutを追加する必要があります

 <com.google.Android.gms.maps.MapView 
    Android:id="@+id/mapview"
    Android:layout_width="fill_parent" 
    Android:layout_height="fill_parent" />

Fragmentのように実装します

public class SomeFragment extends Fragment {

MapView mapView;
GoogleMap map;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)          {
    View v = inflater.inflate(R.layout.some_layout, container, false);

    // Gets the MapView from the XML layout and creates it
    mapView = (MapView) v.findViewById(R.id.mapview);
    mapView.onCreate(savedInstanceState);

    // Gets to GoogleMap from the MapView and does initialization stuff
    map = mapView.getMap();
    map.getUiSettings().setMyLocationButtonEnabled(false);
    map.setMyLocationEnabled(true);

    // Needs to call MapsInitializer before doing any CameraUpdateFactory calls
    try {
        MapsInitializer.initialize(this.getActivity());
    } catch (GooglePlayServicesNotAvailableException e) {
        e.printStackTrace();
    }

    // Updates the location and zoom of the MapView
    CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(new LatLng(43.1, -87.9), 10);
    map.animateCamera(cameraUpdate);

    return v;
}

@Override
public void onResume() {
    mapView.onResume();
    super.onResume();
}

@Override
public void onDestroy() {
    super.onDestroy();
    mapView.onDestroy();
 }

 @Override
 public void onLowMemory() {
    super.onLowMemory();
    mapView.onLowMemory();
  }

}

M Dの答えに追加：

ドキュメント から：

GoogleMapは、getMapAsync（OnMapReadyCallback）を使用して取得する必要があります。 MapViewは、マップシステムとビューを自動的に初期化します。

これによると、GoogleMapを初期化するより適切な方法は、getMapAsyncを使用することです。

クラスはOnMapReadyCallbackを実装する必要があることに注意してください

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.fragment_map_page, container, false);

    mMapView = (MapView) v.findViewById(R.id.map_view);
    mMapView.onCreate(savedInstanceState);
    mMapView.getMapAsync(this); //this is important

    return v;
}

@Override
public void onMapReady(GoogleMap googleMap) {
    mGoogleMap = googleMap;
    mGoogleMap.getUiSettings().setZoomControlsEnabled(true);
    mGoogleMap.addMarker(new MarkerOptions().position(/*some location*/));
    mGoogleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(/*some location*/, 10));
}

@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 onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    mMapView.onSaveInstanceState(outState);
}

@Override
public void onLowMemory() {
    super.onLowMemory();
    mMapView.onLowMemory();
}

誰かがMapView FragmentのKotlinバージョンを探している場合;）

class MapViewKotlinFragment : Fragment(), OnMapReadyCallback {

private var mMap: MapView? = null

override fun onSaveInstanceState(outState: Bundle?) {
    super.onSaveInstanceState(outState)

    mMap?.onSaveInstanceState(outState)
}

override fun onCreateView(inflater: LayoutInflater?, container: ViewGroup?, savedInstanceState: Bundle?): View? {
    val view = inflater?.inflate(R.layout.fragment_map, container, false)

    mMap = view?.findViewById(R.id.mapViewPlaces) as MapView
    mMap?.onCreate(savedInstanceState)
    mMap?.getMapAsync(this)

    return view
}

override fun onResume() {
    super.onResume()
    mMap?.onResume()
}

override fun onPause() {
    super.onPause()
    mMap?.onPause()
}

override fun onStart() {
    super.onStart()
    mMap?.onStart()
}

override fun onStop() {
    super.onStop()
    mMap?.onStop()
}

override fun onDestroy() {
    super.onDestroy()
    mMap?.onDestroy()
}

override fun onLowMemory() {
    super.onLowMemory()
    mMap?.onLowMemory()
}

override fun onMapReady(googleMap: GoogleMap) {
    googleMap.addMarker(MarkerOptions().position(LatLng(0.0, 0.0)).title("Marker"))
}

OnDestroyをオーバーライドまたは呼び出していることを確認します-ViewおよびOnDestroy。何かのようなもの ...

    public override void OnDestroy()
    {            
        base.OnDestroy();
        MapView.OnDestroy();
        OnDestroyView();            
    }

    public override void OnDestroyView()
    {            
        base.OnDestroyView();
        mapReadyCallbackList.Clear();            
}
