关于Android Sqlite数据库

添加数据方法

SqliteHepler hepler = new SqliteHepler(Details_Activity.this);
                SQLiteDatabase db = hepler.getWritableDatabase();
                ContentValues values = new ContentValues();
                values.put("id", list_d.id);
                values.put("ima", list_d.pic.get(0));
                values.put("mar_price", list_d.limitPrice);
                values.put("shop_price", list_d.price);
                values.put("title", list_d.name);
                db.insert(SqliteHepler.TABLE_NAME_USER, null, values);


                Toast.makeText(Details_Activity.this, "已添加收藏", Toast.LENGTH_SHORT).show();
                de_collect.setBackgroundResource(R.drawable.head_button_selected);

查询数据方法

        list_c = new ArrayList<Car_Vo>();
        Cursor c = db.query(false, SqliteHepler.Table_Name_User, null, null, null, null, null, null, null, null);
        while(c.moveToNext()){

            String sid = c.getString(c.getColumnIndex("id"));
            String sima = c.getString(c.getColumnIndex("ima"));
            String sshop_price = c.getString(c.getColumnIndex("shop_price"));
            String stitle = c.getString(c.getColumnIndex("title"));

            car_vo = new Car_Vo();

            car_vo.setId(sid);
            car_vo.setIma(sima);
            car_vo.setPrice(sshop_price);
            car_vo.setName(stitle);

            list_c.add(car_vo);
            Log.i("shop", car_vo.toString());
