如何从android中的ringtonePickerIntent设置所选的单选按钮

Question

我已经保存了所选择的铃声，如下面的代码...

 final Uri uri = data.getParcelableExtra(RingtoneManager.EXTRA_RINGTONE_PICKED_URI);
            SharedPreferences.Editor editor1=JalpiApp.getRingtoneSettings().edit();
            editor1.putString("RINGTONENOTI", uri.toString());
            editor1.commit();

并得到这样......

 SharedPreferences ringtoneSettings = JalpiApp.getRingtoneSettings();
            String ring_notification = ringtoneSettings.getString("RINGTONENOTI", "");

现在如何设置单选按钮的值...如何从ringtonePickerIntent获取radiobuttons的id？
