我想谷歌地图显示用户的位置.我尝试了这段代码,但它在Android 6上无效.

private GoogleMap map;
LocationManager lm;
LocationListener ll;
Location l;

LatLng pos;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.start_layout);

    lm = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
    ll = new LocationListener() {
        @Override
        public void onLocationChanged(Location location) {
            l = (Location) location;
        }

        @Override
        public void onStatusChanged(String provider, int status, Bundle extras) {}

        @Override
        public void onProviderEnabled(String provider) {}

        @Override
        public void onProviderDisabled(String provider) {}
    };

    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.nMap);
    mapFragment.getMapAsync(this);
}

@Override
public void onMapReady(GoogleMap googleMap) {
    map = …

这是我的MainActivity.java:

import android.app.Activity;
import android.app.AlertDialog;
import android.app.ProgressDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.content.Intent;
import android.location.Location;
import android.location.LocationManager;
import android.os.Bundle;
import android.util.Log;
import android.view.MotionEvent;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;

import com.google.android.gms.location.LocationListener;
import com.google.android.gms.location.LocationRequest;


public class MainActivity extends Activity {



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
        LocationListener locationListener = new GetCurrentLocation();
        locationManager.requestLocationUpdates(
                LocationManager.GPS_PROVIDER, 5000, 10, locationListener);
}

这是我的GetCurrentLocation.java:

import android.app.Activity;
import android.content.Context;
import android.location.Address;
import android.location.Geocoder;
import android.location.Location;
import android.location.LocationManager;
import android.os.Bundle;
import android.util.Log;
import …
