第二种方法：

ContentResolver resolver = this.getContentResolver();

   Cursor cursor =
   resolver.query(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, null,
   null, null, null);
   if(cursor.moveToPosition(3)) {
   String path2 =
   cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DATA));
   Log.d("liuyanfeng", "--date---"+path2);
   int id =
     cursor.getInt(cursor.getColumnIndex(MediaStore.Audio.Media._ID));
     Log.d("liuyanfeng", "---id--"+id);
   ContentValues cv = new ContentValues();
   cv.put(MediaStore.Audio.Media.IS_RINGTONE, true);
         cv.put(MediaStore.Audio.Media.IS_NOTIFICATION, false);
         cv.put(MediaStore.Audio.Media.IS_ALARM, false);
   cv.put(MediaStore.Audio.Media.IS_MUSIC, false);
   Uri uri = MediaStore.Audio.Media.getContentUriForPath(path2);
   getContentResolver().update(uri, cv, MediaStore.MediaColumns.DATA + "=?",new String[] {path2});
   Uri newUri = ContentUris.withAppendedId(uri, Long.valueOf(id));
         RingtoneManager.setActualDefaultRingtoneUri(MainActivity.this,
     RingtoneManager.TYPE_RINGTONE, newUri);
