如何使用手机信号塔在Android中找到用户位置，或者如何基于Android中的小区ID获取单元位置？

解决方案

 类MyLocationActivity
     扩展MapActivity {
    MapController mapController;
    MyPositionOverlay positionOverlay;
    @覆盖
    公共无效的onCreate（包savedInstanceState）{
        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.main）;
        图形页面图形页面=（图形页面）findViewById（R.id.mapview）;
        mapController = mapView.getController（）;
        //配置图的显示选项
        mapView.setSatellite（真正的）;
        mapView.setStreetView（真正的）;
        mapView.displayZoomControls（假）;
        mapController.setZoom（17）;
        //添加MyPositionOverlay
        positionOverlay =新MyPositionOverlay（）;
        名单＆LT;覆盖＆GT;叠加=调用MapView.getOverlays（）;
        overlays.add（positionOverlay）;
        LocationManager locationmanager;
        字符串情形= Context.LOCATION_SERVICE;
        locationmanager =（LocationManager）getSystemService（上下文）;
        字符串提供商= LocationManager.NETWORK_PROVIDER;
        位置位置= locationmanager.getLastKnownLocation（供应商）;
        updateWithNewLocation（位置）;
    }
    私人无效updateWithNewLocation（位置定位）{
        如果（位置！= NULL）{
            positionOverlay.setLocation（位置）;
            双纬度= location.getLatitude（）* 1E6;
            双LON = location.getLongitude（）* 1E6;
            的GeoPoint点=新的GeoPoint（lat.intValue（），lon.intValue（））;
            mapController.animateTo（点）;
        }
        其他{


        }

    }

    @覆盖
    保护的布尔isRouteDisplayed（）{
        // TODO自动生成方法存根

解决方案

class MyLocationActivity
     extends MapActivity {
    MapController mapController;
    MyPositionOverlay positionOverlay;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        MapView mapView = (MapView) findViewById(R.id.mapview);
        mapController = mapView.getController();
        // Configure the map display options
        mapView.setSatellite(true);
        mapView.setStreetView(true);
        mapView.displayZoomControls(false);
        mapController.setZoom(17);
        // Add the MyPositionOverlay
        positionOverlay = new MyPositionOverlay();
        List<Overlay> overlays = mapView.getOverlays();
        overlays.add(positionOverlay);
        LocationManager locationmanager;
        String context=Context.LOCATION_SERVICE;
        locationmanager=(LocationManager) getSystemService(context);
        String provider=LocationManager.NETWORK_PROVIDER;
        Location location= locationmanager.getLastKnownLocation(provider);
        updateWithNewLocation(location);
    }
    private void updateWithNewLocation(Location location) {
        if(location!=null){
            positionOverlay.setLocation(location);
            Double lat=location.getLatitude()*1E6;
            Double lon=location.getLongitude()*1E6;
            GeoPoint point = new GeoPoint(lat.intValue(),lon.intValue());
            mapController.animateTo(point);
        }
        else{


        }

    }

    @Override
    protected boolean isRouteDisplayed() {
        // TODO Auto-generated method stub
        return false;
    }
}
