If you know ContactID, you can get the existing ringtone like this:

Public String Getcontactrington (long contactId) {        String Rington = "";        string[] projection = {ContactsContract.Contacts.CUSTOM_RINGTONE};        Uri Contacturi = Contenturis.withappendedid (                ContactsContract.Contacts.CONTENT_URI, contactId);        cursor cursor = this.getcontentresolver (). Query (Contacturi,                projection, NULL, NULL, NULL);        if (cursor = = null) {            return rington;        }        while (Cursor.movetonext ()) {            Rington = cursor.getstring (0);            break;        }        Cursor.close ();        return Rington;    }

Use the following code to call the system interface to change the ringtone:

 private void Dopickringtone (String ringtones) {Intent Intent = new Intent (ringtonemanager.action_ringtone_picker)        ;        Intent.putextra (Ringtonemanager.extra_ringtone_show_default, true);        Intent.putextra (Ringtonemanager.extra_ringtone_type, Ringtonemanager.type_ringtone);        Intent.putextra (Ringtonemanager.extra_ringtone_show_silent, false);            try {Uri Ringtoneuri; if (ringtones! = null && ringtones.length () > 0) {ringtoneuri = Uri.parse (ri            Ngtones); } else {Ringtoneuri = Ringtonemanager. Getdefaulturi (Ringtonemanager.type_ringtone)            ;            } Intent.putextra (Ringtonemanager.extra_ringtone_existing_uri, Ringtoneuri);        Startactivityforresult (Intent, resutl_ringtone_picked);        } catch (Exception ex) {mktlog.i (TAG, "Dopickringtone:" + ex.tostring ()); }    }

Select the end of the ringtone click confirm:

  private void handleringtonepicked (Uri pickeduri) {        Updatecontactrington (mcontactid,pickeduri.tostring ());    }    public boolean Updatecontactrington (Long contactId, String Rington) {        contentvalues values = new Contentvalues (); 
   values.put (ContactsContract.Contacts.CUSTOM_RINGTONE, Rington);        Uri Contacturi = Contenturis.withappendedid (                ContactsContract.Contacts.CONTENT_URI, contactId);        This.getcontentresolver (). Update (Contacturi, values, NULL, NULL);        return true;    }
