使用.GetMapAsync代替.getMap方法与Google Play服务(Xamarin)

Question

旧代码以这种方式完美运行:

LatLng location = new LatLng (myClass.myLocation.Latitude, myClass.myLocation.Longitude);
CameraPosition.Builder builder = CameraPosition.InvokeBuilder ();
builder.Target (location);
builder.Zoom (18);
CameraPosition cameraPosition = builder.Build ();
MapsInitializer.Initialize (this);
CameraUpdate cameraUpdate = CameraUpdateFactory.NewCameraPosition (cameraPosition);
MapFragment googleMap = FragmentManager.FindFragmentById<MapFragment> (Resource.Id.map);
theMap = googleMap.Map;
if (theMap != null) {
    theMap.MapType = GoogleMap.MapTypeNormal;
    theMap.MoveCamera (cameraUpdate);
}

但是现在它.Map已经过时并且已经过时了,我必须以.GetMapAsync某种方式使用:

theMap = googleMap.GetMapAsync (IOnMapReadyCallback);

但我不明白怎么做.

有人可以帮助我吗？

您的地图片段类必须实现OnMapReadyCallback并覆盖onMapReady():

@Override
public void onMapReady(final GoogleMap map) {
    this.map = map;
    map.setMyLocationEnabled(true);
}

在您的onCreateView用途getMapAsync()中设置片段的回调:

MapFragment mapFragment = (MapFragment) getFragmentManager()
    .findFragmentById(R.id.map); mapFragment.getMapAsync(this);
