我是 android 的新手，我的项目是添加一个产品和他的参考资料（nom、qte_alerte、prix_achat、prix_vente、description）日志猫说我认为这不是描述的笨拙。问题出在哪里。。我可以在哪里添加它，我真的需要这个应用程序。我需要在 logCat 中显示我添加的产品列表（产品 ajouté）

您的 sql 查询错误：

Caused by: android.database.sqlite.SQLiteException: no such column: description (code 1): , while compiling: SELECT id, nom_produit, prix_achat, prix_vente, description FROM produittable ORDER BY nom_produit asc

确保您在“produittable”表中有“描述”列

根据你的代码：

 @Override
    public void onCreate(SQLiteDatabase db) {
        db.execSQL("CREATE TABLE " + TABLE_PRODUIT + " (id INTEGER PRIMARY KEY, nom_produit TEXT NOT NULL, quntité_alerte TEXT NOT NULL, prix_achat TEXT NOT NULL, prix_vente TEXT NOT NULL, description_produit TEXT NOT NULL)");
    }

您正在创建列“ description_produit ”
