Android :Wie man die Aktuelle Position in Längen-und Breitengrad?

Will ich speichern, aktuelle Position zu Datenbank wenn ich auf Button.

Dem Speicherort gespeichert, aber es ist empfangen, 0.0 ,0.0 weiß nicht, wo ist der Fehler in meinem code Hier poste ich meine komplette code für diese bitte helfen Sie mir aus dieser.

immer aktuelle Lage

GetCurrentGPSLocation gps = new GetCurrentGPSLocation(getActivity());

            //check if GPS enabled
            if (gps.canGetLocation()) {
                double latitude = gps.getLatitude();
                double longitude = gps.getLongitude();
                //\n is for new line
                lat.setText( ""+latitude);
                longi.setText("" +longitude);
                latitude12=lat.getText().toString();
                longitude12=longi.getText().toString();
                Toast.makeText(getActivity(), "Your Location is - \nLat: " + latitude + "\nLong: " + longitude, Toast.LENGTH_LONG).show();

                longi.setVisibility(View.INVISIBLE);
                lat.setVisibility(View.INVISIBLE);
            } else {
                //can't get location
                //GPS or Network is not enabled
                //Ask user to enable GPS/network in settings
                gps.showSettingsAlert();
