这是我的xml和java

 <fragment xmlns:android="http://schemas.android.com/apk/res/android"

java代码

public class mapFrag  extends  android.support.v4.app.Fragment implements OnMapReadyCallback, LocationListener {


public static FragmentManager fragmentManager;
private GoogleMap map;
private LocationManager locationManager;
private boolean isGPSEnabled, isNetworkEnabled, isGPSTrackingEnabled;
private String provider_info;
private static String TAG = MapsActivity.class.getName();
private Location location;
private double latitude;
private double longitude;
// The minimum distance to change updates in meters
private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10; // 10 meters

// The minimum time between updates in milliseconds
private static final long MIN_TIME_BW_UPDATES = 1000 * 60 * 1; // 1 minute


public mapFrag() {
    // Required empty public constructor
}



@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);



}

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

    // Inflate the layout for this fragment
    View view = inflater.inflate(R.layout.fragment_map, container, false);
    getMyLocation();
    return view;

}


@Override
public void onLocationChanged(Location location) {

    //txtOutput.setText(location.toString());
    System.out.println(String.valueOf(location.getLatitude()));
    System.out.println(String.valueOf(location.getLongitude()));


    try {

        map.clear();
    } catch (Exception e) {
    }
    LatLng mypos = new LatLng(location.getLatitude(), location.getLongitude());

    //camera annimation
    CameraPosition camPos = new CameraPosition.Builder().target(mypos)
            .zoom(70)
            .bearing(45)
            .tilt(65)
            .build();

    CameraUpdate camUpd3 = CameraUpdateFactory.newCameraPosition(camPos);

 map.animateCamera(camUpd3);
    map.addMarker(new MarkerOptions().position(mypos).title("here i am !!"));

    // mMap.moveCamera(CameraUpdateFactory.newLatLng(mypos));
    //map.moveCamera(CameraUpdateFactory.newLatLng(mypos));


}

@Override
public void onMapReady(GoogleMap googleMap) {
    map= googleMap;


    if (ActivityCompat.checkSelfPermission(getActivity(), android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        // TODO: Consider calling

        //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
        //                                          int[] grantResults)
        // to handle the case where the user grants the permission. See the documentation
        // for ActivityCompat#requestPermissions for more details.
        return;
    }
    map.setMyLocationEnabled(true);
    LocationManager locationManager = (LocationManager) getActivity().getSystemService(getActivity().LOCATION_SERVICE);


    return;

}

void getMyLocation(){


    // definition of the location manager

    LocationManager locManager = (LocationManager) getActivity().getSystemService(Context.LOCATION_SERVICE);
    //definition of the listenner
    LocationListener locationListener = new LocationListener() {
        // Called when a new location is found by the network location provider.
        public void onLocationChanged(Location location) {
            // setting the camera of the map to positionate the marker in the current position
            LatLng myLaLn = new LatLng(location.getLatitude(), location.getLongitude());

            CameraPosition camPos = new CameraPosition.Builder().target(myLaLn)
                    .zoom(15)
                    .bearing(45)
                    .tilt(70)
                    .build();

            CameraUpdate camUpd3 = CameraUpdateFactory.newCameraPosition(camPos);

            map.animateCamera(camUpd3);

            //  setting the marker in the current position

            Marker marker = map.addMarker(new MarkerOptions()
                    .position(new LatLng(location.getLatitude(), location.getLongitude()))
                    .title("My position")
                    .snippet("Population: 776733"));


        }


    };
}}

这就是我在on create function中调用它的方式

     mapFrag myMap = new mapFrag();
        android.support.v4.app.FragmentManager fragmentManager=getSupportFragmentManager();

        android.support.v4.app.FragmentTransaction transaction = fragmentManager.beginTransaction();
        transaction.add(R.id.myHomeContainer,myMap,"test");

        transaction.commit();

在活动
