            @Override
            public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {

                String selected = langeBtn.getSelectedItem().toString();
               // editor.putString("selected", selected);
               // editor.commit();
            }

            public void onNothingSelected(AdapterView<?> arg0) {
