getmap（）已被棄用並使用getmapAsync？

Question

我正在製作一個使用android studio的預訂應用程序。我已經添加了一個地圖片段，但是我收到了錯誤消息getmap（）已被棄用，我想使用getMapAsync（）代替。我試了一下，但得到了更多的錯誤。請幫助我。謝謝。

public class HomeActivity extends Fragment implements View.OnClickListener,GoogleApiClient.ConnectionCallbacks,GoogleApiClient.OnConnectionFailedListener,GoogleMap.OnMapClickListener,GoogleMap.OnMarkerDragListener,{ 
private GoogleMap map; 
private static View v; 
private GoogleApiClient mGoogleApiClient; 
double latitude,longitude; 
boolean centeronCurrent= true, syncWithServer= true, trackDriverBoolean= true, waitForRideToEnd=true; 
TextView selectPickup, statusText; 
Button requesttaxi; 
LatLng currentLocation; 
int shortestTime; 
int nearbyTaxis,taxicount; 
String driverid="", currentRideid=""; 
ArrayList<Marker> markers= new ArrayList<Marker>(); 


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

    if (v!= null){ 
     ViewGroup parent= (ViewGroup) v.getParent(); 
     if (parent!= null) 
      parent.removeView(v); 
    } 
    try { 
     v= inflater.inflate(R.layout.home,container,false); 
    } 
    catch (InflateException e){ 
     e.printStackTrace(); 
    } 
    map= ((SupportMapFragment)getChildFragmentManager().findFragmentById(R.id.map)).getMap(); 
    map.setMyLocationEnabled(true); 

    map.setMapType(GoogleMap.MAP_TYPE_NORMAL); 
    map.setOnMapClickListener(this); 
    map.setOnMarkerDragListener(this); 

    requesttaxi= (Button) v.findViewById(R.id.request_taxi); 
    requesttaxi.setOnClickListener(this); 
    statusText=(TextView) v.findViewById(R.id.status_text); 
    statusText.setVisibility(View.INVISIBLE); 

    SharedPreferences sp = getActivity().getSharedPreferences("Session", Context.MODE_PRIVATE); 
    SharedPreferences.Editor editor; 
    editor=sp.edit(); 
    String location= sp.getString("location",""); 

    mGoogleApiClient = new GoogleApiClient.Builder(getActivity()) 
      .addConnectionCallbacks(this) 
      .addOnConnectionFailedListener(this) 
      .addApi(LocationServices.API) 
      .build(); 

    selectPickup= (TextView) v.findViewById(R.id.select_location); 
    selectPickup.setOnClickListener(this); 
    if (location.equals("")) 
    { 
     selectPickup.setText("Select Pick up Location"); 
    } 
    else { 
     String latstr= sp.getString("locationlat",""); 
     String longstr= sp.getString("locationlong",""); 
     latitude= Double.parseDouble(latstr); 
     longitude= Double.parseDouble(longstr); 
     selectPickup.setText(location); 

     editor.putString("location",""); 
     editor.putString("locationlat",""); 
     editor.putString("locationlong",""); 
     editor.commit(); 
     centeronCurrent=false; 
    } 

    mGoogleApiClient.connect(); 
    return v; 

}

你的地圖片段的類必須實現OnMapReadyCallback，並覆蓋onMapReady()
