Question

当我扩展MapFragment时，这个错误带有十字标志：构造函数Geocoder（Map_Tracker，Locale）是undefined.Also我导入：import android.location.Geocoder; 我做了片段类和下面的代码我删除了一些代码：

    public class Map_Tracker extends MapFragment {
    MapView myMapView;
    View rootView;
    public Map_Tracker() { }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // TODO Auto-generated method stub
         rootView = inflater.inflate(R.layout.frag_tracker, container, false);

         myMapView = (MapView)rootView.findViewById(R.id.mapView);
            updateWithNewLocation(location);

        return rootView;       
    }


        private void updateWithNewLocation(Location location) {
            // TODO Auto-generated method stub

            String latLongString;
            TextView myLocationText;
            myLocationText = (TextView)rootView.findViewById(R.id.textView1);

            String addressString = "No Address Found";

            if(location != null)
            {
            // Update the map Location
                Double geoLat = location.getLatitude()*1E6;
                Double geoLng = location.getLongitude()*1E6;

                GeoPoint point = new GeoPoint(geoLat.intValue(),geoLng.intValue());

                mapController.animateTo(point);
                Double lat = location.getLatitude();
                Double lng = location.getLongitude();
                Geocoder gc = new Geocoder(Map_Tracker.this, Locale.getDefault());

                try
                {
                    List<Address> addresses = gc.getFromLocation(latitude, longitude, 1);
                    StringBuilder sb = new StringBuilder();
                }   
        }
    }

//这一行出错：

Geocoder gc = new Geocoder(Map_Tracker.this, Locale.getDefault());

Answer 1

试试这个

   Geocoder gc = new Geocoder(getActivity(), Locale.getDefault());

而不是

   Geocoder gc = new Geocoder(Map_Tracker.this, Locale.getDefault());

在片段

中

构造函数Geocoder（Map_Tracker，Locale）未定义
