Cursor cursor=db.query("missing",new String[]{ "variety", "old ", "hair","where_from","flesh", "sex" },null,null,null,null,null);
        List<Map<String,Object>> items=new ArrayList<Map<String,Object>>();
        cursor.moveToFirst();
       //叫出資料庫的資料
        for(int i=0;i< cursor.getCount();i++){
           Map<String,Object> item=new HashMap<String,Object>();
           item.put("variety",cursor.getString(0));
           item.put("old",cursor.getString(1));
           item.put("hair",cursor.getString(2));
           item.put("where_from",cursor.getString(3));
           item.put("flesh",cursor.getString(4));
            item.put("sex",cursor.getString(5));
           items.add(item);//新增
           cursor.moveToNext();//移下一筆資料
        }
        SimpleAdapter SA=new SimpleAdapter(this,items,R.layout.people_look_for,new String[]{"variety","where_from","sex"},new int[]{R.id.place,R.id.variety_thing,R.id.sex});
        LV1.setAdapter(SA);
    ---->  String test = items.toString();

列出的資料會是全部的資料 如果我想指定"variety"這個欄位下的 我該怎麼做
