推荐答案

试试这个

public class MyLocationOnMap extends MapActivity {

       private LocationManager hdLocMgr;
       private String hdLocProvider;


       onCreate(...) {
            :
         Criteria hdCrit = new Criteria();
         hdCrit.setAccuracy(Criteria.ACCURACY_COARSE);
         hdCrit.setAltitudeRequired(false);
         hdCrit.setBearingRequired(false);
         hdCrit.setCostAllowed(true);
         hdCrit.setPowerRequirement(Criteria.POWER_LOW);

         hdLocMgr = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

         hdLocProvider = hdLocMgr.getBestProvider(hdCrit, true); 

         Location location = hdLocMgr.getLastKnownLocation(hdLocProvider);

         Double dlat = location.getLatitude();
         Double dlon = location.getLongitude();
                 :
       }

}
