Answer 1

代码来获得用户

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); 


} 

此代码的位置，从经纬度

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; 
    } 

} 

获得地址，你必须在谷歌API控制台 注册该应用程序的代码for Android 6.0 plus pay attation to the listeners .. 这是一个工作代码。
