获取用户位置的代码

  public void getMyLocation(Activity activity) {
    int requestPermissionsCode = 50;
    LocationManager locationManager = (LocationManager) activity.getSystemService(Context.LOCATION_SERVICE);
    if (ActivityCompat.checkSelfPermission(activity, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(activity, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, requestPermissionsCode);
        return;
    }
    Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
    if (location != null) {
        LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
        if (locationListener != null)
            locationListener.onLocationFound(latLng);
        return;
    }


    locationManager.requestSingleUpdate(LocationManager.GPS_PROVIDER, new SingleUpdateListener(), null);


}

此代码从LatLng获取地址

  public Address getLocationFromLatLng(Context context, LatLng latLng) {
    android.location.Geocoder geoCoder = new Geocoder(context, Locale.getDefault());

    try {
        return geoCoder.getFromLocation(latLng.latitude, latLng.longitude, 1).get(0);
    } catch (IOException e) {
        return null;
    }

}

您必须在Google API控制台上注册该应用程序该代码适用于Android 6.0 加上对听众的敬意这是一个有效的代码。
