我正在开发一个Android应用程序,它在地图中显示用户的当前位置。

几小时后,我发现了错误,locationManager没有实现位置。

我把代码放在locationManager:

mapa = ((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.mapaTapas)).getMap();

String serviceString = Context.LOCATION_SERVICE;
LocationManager locationManager = (LocationManager)getSystemService (serviceString);
String proovedor1 = LocationManager.GPS_PROVIDER;
locationManager.getLastKnownLocation(proovedor1);
String proovedor2 = LocationManager.NETWORK_PROVIDER;
locationManager.getLastKnownLocation(proovedor2);

locationManager.requestLocationUpdates(proovedor1, 5000, 5, new LocationListener()
{
@Override
public void onStatusChanged(String arg0, int arg1,Bundle arg2) { }

@Override
public void onProviderEnabled(String arg0) {}

@Override
public void onProviderDisabled(String arg0) {}

@Override
public void onLocationChanged(Location Location)
   {
       location=Location;
   }
});

locationManager.requestLocationUpdates(proovedor2, 5000, 5, new LocationListener()
{
@Override
public void onStatusChanged(String arg0, int arg1,Bundle arg2) { }

@Override
public void onProviderEnabled(String arg0) {}

@Override
public void onProviderDisabled(String arg0) {}

@Override
public void onLocationChanged(Location Location)
{
    location=Location;
    }
});

location = locationManager.getLastKnownLocation(towers);

    if(location != null){

        glat = location.getLatitude();
        glon = location.getLongitude();

        Log.i("location", "latitud: "+glat);
        Log.i("location", "latitud: "+glon);

}

cp = new CameraPosition.Builder()
        .target(new LatLng(glat, glon))
        .zoom(15)
        .build();     
    mapa.animateCamera(CameraUpdateFactory.newCameraPosition(cp));

我需要在glat和glon中保存位置的当前值,如果它是posibble实现一些方法来自动刷新它

现在,LocationManager界面为introduced,无法从OnMyLocationChangeListener手动请求位置更新。

您只需要启用我的位置图层(map.setMyLocationEnabled(true)),设置监听器(map.setOnMyLocationChangeListener(this))并使用当前位置(例如动画相机)执行任何操作,然后传回给您相应的回调(通过实现该接口提供)。
